The Boeing B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber is capable of carrying up to Script error: No such module "convert". of weapons.[4]

Beginning with the successful contract bid in June 1946, the B-52 design evolved from a straight wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. The B-52 took its maiden flight in April 1952. Built to carry nuclear weapons for Cold War-era deterrence missions, the B-52 Stratofortress replaced the Convair B-36. A veteran of several wars, the B-52 has dropped only conventional munitions in combat. The B-52's official name Stratofortress is rarely used; informally, the aircraft has become commonly referred to as the BUFF (Big Ugly Fat Fucker).[5][Note 1]

The B-52 has been in active service with the USAF since 1955. As of 2012, 85 were in active service with nine in reserve. The bombers flew under the Strategic Air Command (SAC) until it was inactivated in 1992 and its aircraft absorbed into the Air Combat Command (ACC); in 2010 all B-52 Stratofortresses were transferred from the ACC to the new Air Force Global Strike Command (AFGSC). Superior performance at high subsonic speeds and relatively low operating costs have kept the B-52 in service despite the advent of later, more advanced aircraft, including the canceled Mach 3 B-70 Valkyrie, the variable-geometry B-1 Lancer, and the stealth B-2 Spirit. The B-52 completed fifty years of continuous service with its original operator in 2005; after being upgraded between 2013 and 2015, it is expected to serve into the 2040s.[Note 2]

On 23 November 1945, Air Materiel Command (AMC) issued desired performance characteristics for a new strategic bomber "capable of carrying out the strategic mission without dependence upon advanced and intermediate bases controlled by other countries".[12] The aircraft was to have a crew of five or more turret gunners, and a six-man relief crew. It was required to cruise at 300 mph (260 knots, 480 km/h) at 34,000 feet (10,400 m) with a combat radius of 5,000 miles (4,300 nautical miles, 8,000 km). The armament was to consist of an unspecified number of 20 mm cannon and 10,000 pounds (4,500 kg) of bombs.[13] On 13 February 1946, the Air Force issued bid invitations for these specifications, with Boeing, Consolidated Aircraft, and Glenn L. Martin Company submitting proposals.[13]

On 5 June 1946, Boeing's Model 462, a straight-wing aircraft powered by six Wright T35 turboprops with a gross weight of 360,000 pounds (160,000 kg) and a combat radius of 3,110 miles (2,700 nmi, 5,010 km), was declared the winner.[14] On 28 June 1946, Boeing was issued a letter of contract for US$1.7 million to build a full-scale mock-up of the new XB-52 and do preliminary engineering and testing.[15] However, by October 1946, the air force began to express concern about the sheer size of the new aircraft and its inability to meet the specified design requirements.[16] In response, Boeing produced Model 464, a smaller four-engine version with a 230,000 pound (105,000 kg) gross weight, which was briefly deemed acceptable.[16][17]

Subsequently, in November 1946, the Deputy Chief of Air Staff for Research and Development, General Curtis LeMay, expressed the desire for a cruise speed of 400 miles per hour (345 kn, 645 km/h), to which Boeing responded with a 300,000 lb (136,000 kg) aircraft.[18] In December 1946, Boeing was asked to change their design to a four-engine bomber with a top speed of 400 miles per hour, range of 12,000 miles (10,000 nmi, 19,300 km), and the ability to carry a nuclear weapon; in total, the aircraft could weigh up to 480,000 pounds (220,000 kg).[19] Boeing responded with two models powered by the T-35 turboprops. The Model 464-16 was a "nuclear only" bomber with a 10,000 pound (4,500 kg) payload, while the Model 464-17 was a general purpose bomber with a 9,000 pound (4,000 kg) payload.[19] Due to the cost associated with purchasing two specialized aircraft, the air force selected Model 464-17 with the understanding that it could be adapted for nuclear strikes.[20]

In June 1947, the military requirements were updated and the Model 464-17 met all of them except for the range.[21] It was becoming obvious to the air force that, even with the updated performance, the XB-52 would be obsolete by the time it entered production and would offer little improvement over the Convair B-36; as a result, the entire project was postponed for six months.[22] During this time, Boeing continued to perfect the design, which resulted in the Model 464-29 with a top speed of 455 miles per hour (395 kn, 730 km/h) and a 5,000-mile range.[23] In September 1947, the Heavy Bombardment Committee was convened to ascertain performance requirements for a nuclear bomber. Formalized on 8 December 1947, these requirements called for a top speed of 500 miles per hour (440 kn, 800 km/h) and an 8,000 mile (7,000 nmi, 13,000 km) range, far beyond the capabilities of 464-29.[22][24]

The outright cancellation of the Boeing contract on 11 December 1947 was staved off by a plea from its president William McPherson Allen to the Secretary of the Air Force Stuart Symington.[25] Allen reasoned that the design was capable of being adapted to new aviation technology and more stringent requirements.[26] In January 1948 Boeing was instructed to thoroughly explore recent technological innovations, including aerial refueling and the flying wing.[27] Noting stability and control problems Northrop was experiencing with their YB-35 and YB-49 flying wing bombers, Boeing insisted on a conventional aircraft, and in April 1948 presented a US$30 million (US$294 million today[28]) proposal for design, construction, and testing of two Model 464-35 prototypes.[29] The Model 464-35 design had a similar configuration as a later Tupolev design that was built for the Soviet Union, the Tupolev Tu-95 Bear strategic bomber.[30] Further revisions during 1948 resulted in an aircraft with a top speed of 513 miles per hour (445 kn, 825 km/h) at 35,000 feet (10,700 m), a range of 6,909 miles (6,005 nmi, 11,125 km), and a 280,000 pounds (125,000 kg) gross weight, which included 10,000 pounds (4,500 kg) of bombs and 19,875 US gallons (75,225 L) of fuel.[31][32]

In May 1948, AMC asked Boeing to incorporate the previously discarded, but now more fuel-efficient, jet engine into the design.[33] That resulted in the development of yet another revision – in July 1948, Model 464-40 substituted Westinghouse J40 turbojets for the turboprops.[34] The air force project officer who reviewed the Model 464-40 was favorably impressed, especially since he had already been thinking along similar lines. Nevertheless, the government was concerned about the high fuel consumption rate of the jet engines of the day, and directed that Boeing still use the turboprop-powered Model 464-35 as the basis for the XB-52. Although he agreed that turbojet propulsion was the future, General Howard A. Craig, Deputy Chief of Staff for Material, was not very keen on a jet-powered B-52, since he felt that the jet engine had not yet progressed sufficiently to permit skipping an intermediate turboprop stage. However, Boeing was encouraged to continue turbojet studies even without any expected commitment to jet propulsion.[35][36]

On Thursday, 21 October 1948, Boeing engineers George S. Schairer, Art Carlsen and Vaughn Blumenthal presented the design of a four-engine turboprop bomber to the chief of bomber development, Colonel Pete Warden. Warden was disappointed by the projected aircraft and asked if the Boeing team could come up with a proposal for a four-engine turbojet bomber. Joined by Ed Wells, Boeing vice president of engineering, the engineers worked that night in the Hotel Van Cleve in Dayton, Ohio, redesigning Boeing's proposal as a four-engine turbojet bomber. On Friday, Colonel Warden looked over the information and asked for a better design. Returning to the hotel, the Boeing team was joined by Bob Withington and Maynard Pennell, two top Boeing engineers who were in town on other business.[37]

By late Friday night, they had laid out what was essentially a new airplane. The new design (464-49) built upon the basic layout of the B-47 Stratojet with 35 degree swept wings, eight engines paired in four underwing pods, and bicycle landing gear with wingtip outrigger wheels.[38] A notable feature of the landing gear was the ability to pivot the main landing gear up to 20° from the aircraft centerline to increase safety during crosswind landings.[39] After a trip to a hobby shop for supplies, Schairer set to work building a model. The rest of the team focused on weight and performance data. Wells, who was also a skilled artist, completed the aircraft drawings. On Sunday, a stenographer was hired to type a clean copy of the proposal. On Monday, Schairer presented Colonel Warden with a neatly bound 33-page proposal and a 14-inch scale model.[37] The aircraft was projected to exceed all design specifications.[40]

Although the full-size mock-up inspection in April 1949 was generally favorable, range again became a concern since the J40s and early model J57s had excessive fuel consumption.[41] Despite talk of another revision of specifications or even a full design competition among aircraft manufacturers, General LeMay, now in charge of Strategic Air Command, insisted that performance should not be compromised due to delays in engine development.[42][43] In a final attempt to increase range, Boeing created the larger 464-67, stating that once in production, the range could be further increased in subsequent modifications.[44] Following several direct interventions by LeMay,[45] Boeing was awarded a production contract for thirteen B-52As and seventeen detachable reconnaissance pods on 14 February 1951.[46] The last major design change—also at General LeMay's insistence—was a switch from the B-47 style tandem seating to a more conventional side-by-side cockpit, which increased the effectiveness of the copilot and reduced crew fatigue.[47] Both XB-52 prototypes featured the original tandem seating arrangement with a framed bubble-type canopy.[48]


The YB-52, the second XB-52 modified with more operational equipment, first flew on 15 April 1952 with "Tex" Johnston as pilot.[49][50] During ground testing on 29 November 1951, the XB-52's pneumatic system failed during a full-pressure test; the resulting explosion severely damaged the trailing edge of the wing, necessitating considerable repairs. A two-hour, 21-minute proving flight from Boeing Field, King County, in Seattle, Washington to Larson AFB was undertaken with Boeing test pilot Johnston and air force Lieutenant Colonel Guy M. Townsend.[51] The XB-52 followed on 2 October 1952.[52] The thorough development,[Note 3] including 670 days in the wind tunnel and 130 days of aerodynamic and aeroelastic testing, paid off with smooth flight testing. Encouraged, the air force increased its order to 282 B-52s.[54]

Only three of the 13 B-52As ordered were built.[62] All were returned to Boeing, and used in their test program.[55] On 9 June 1952, the February 1951 contract was updated to order the aircraft under new specifications. The final 10, the first aircraft to enter active service, were completed as B-52Bs.[55] At the roll out ceremony on 18 March 1954, Air Force Chief of Staff General Nathan Twining said:

The long rifle was the great weapon of its day. ... today this B-52 is the long rifle of the air age.[63][64]

The B-52B was followed by progressively improved bomber and reconnaissance variants, culminating in the B-52G and turbofan B-52H. To allow rapid delivery, production lines were set up both at its main Seattle factory and at Boeing's Wichita facility. More than 5,000 companies were involved in the massive production effort, with 41% of the airframe being built by subcontractors.[65] The prototypes and all B-52A, B and C models (90 aircraft)[66] were built at Seattle. Testing of aircraft built at Seattle caused problems due to jet noise, which led to the establishment of curfews for engine tests. Aircraft were ferried Script error: No such module "convert". east on their maiden flights to Larson Air Force Base near Moses Lake, where they were fully tested.[67]

As production of the B-47 came to an end, the Wichita factory was phased in for B-52D production, with Seattle responsible for 101 D-models and Wichita 69.[68] Both plants continued to build the B-52E, with 42 built at Seattle and 58 at Wichita,[69] and the B-52F (44 from Seattle and 45 from Wichita).[70] For the B-52G, it was decided in 1957 to transfer all production to Wichita, which freed up Seattle for other tasks (in particular the production of airliners).[71][72] Production ended in 1962 with the B-52H, with 742 aircraft built, plus the original two prototypes.[73]



The B-52 shared many technological similarities with the preceding Boeing B-47 Stratojet strategic bomber. The two aircraft used the same basic design, such as swept wings and podded jet engines,[74] and the cabin included the crew ejection systems.[75] On the B-52D, the pilots and electronic countermeasures (EDM) operator ejected upwards, while the lower deck crew ejected downwards; until the B-52G, the gunner had to jettison the tail gun to bail-out.[76]

Structural fatigue was accelerated by at least a factor of eight in a low-altitude flight profile over that of high-altitude flying, requiring costly repairs to extend service life. In the early 1960s, the three-phase High Stress program was launched to counter structural fatigue, enrolling aircraft at 2,000 flying hours.[78][79] Follow-up programs were conducted, such as a 2,000-hour service life extension to select airframes in 1966–1968, and the extensive Pacer Plank reskinning, completed in 1977.[72][80] The wet wing introduced on G and H models was even more susceptible to fatigue, experiencing 60% more stress during flight than the old wing. The wings were modified by 1964 under ECP 1050.[81] This was followed by a fuselage skin and longeron replacement (ECP 1185) in 1966, and the B-52 Stability Augmentation and Flight Control program (ECP 1195) in 1967.[81] Fuel leaks due to deteriorating Marman clamps continued to plague all variants of the B-52. To this end, the aircraft were subjected to Blue Band (1957), Hard Shell (1958), and finally QuickClip (1958) programs. The latter fitted safety straps that prevented catastrophic loss of fuel in case of clamp failure.[82]

In September 2006, the B-52 became one of the first US military aircraft to fly using alternative fuel. It took off from Edwards Air Force Base with a 50/50 blend of Fischer-Tropsch process (FT) synthetic fuel and conventional JP-8 jet fuel, which burned in two of the eight engines.[83] On 15 December 2006, a B-52 took off from Edwards with the synthetic fuel powering all eight engines, the first time an air force aircraft was entirely powered by the blend. The seven-hour flight was considered a success.[83] This program is part of the Department of Defense Assured Fuel Initiative, which aims to reduce crude oil usage and obtain half of its aviation fuel from alternative sources by 2016.[83] On 8 August 2007, Air Force Secretary Michael Wynne certified the B-52H as fully approved to use the FT blend.[84]

Ongoing problems with avionics systems were addressed in the Jolly Well program, completed in 1964, which improved components of the AN/ASQ-38 bombing navigational computer and the terrain computer. The MADREC (Malfunction Detection and Recording) upgrade fitted to most aircraft by 1965 could detect failures in avionics and weapons computer systems, and was essential in monitoring the Hound Dog missiles. The electronic countermeasures capability of the B-52 was expanded with Rivet Rambler (1971) and Rivet Ace (1973).[85]

To improve operations at low altitude, the AN/ASQ-151 Electro-Optical Viewing System (EVS), which consisted of a Low Light Level Television (LLLTV) and a Forward looking infrared (FLIR) system mounted in blisters under the noses of B-52Gs and Hs between 1972 and 1976.[86] The navigational capabilities of the B-52 were later augmented with the addition of GPS in the 1980s.[87] The IBM AP-101, also used on the Rockwell B-1 Lancer bomber and the Space Shuttle, was the B-52's main computer.[88]

In 2007 the LITENING targeting pod was fitted, which increased the effectiveness of the aircraft in the attack of ground targets with a variety of standoff weapons, using laser guidance, a high-resolution forward-looking infrared sensor (FLIR), and a CCD camera used to obtain target imagery.[89] LITENING pods have been fitted to a wide variety of other US aircraft, such as the McDonnell Douglas F/A-18 Hornet, the General Dynamics F-16 Fighting Falcon and the McDonnell Douglas AV-8B Harrier II.[90]


The ability to carry up to 20 AGM-69 SRAM nuclear missiles was added to G and H models, starting in 1971.[91] To further improve its offensive ability, air-launched cruise missiles (ALCMs) were fitted.[92] After testing of both the air force-backed Boeing AGM-86 and the navy-backed General Dynamics AGM-109 Tomahawk, the AGM-86B was selected for operation by the B-52 (and ultimately by the B-1 Lancer).[93] A total of 194 B-52Gs and Hs were modified to carry AGM-86s, carrying 12 missiles on underwing pylons, with 82 B-52Hs further modified to carry another eight missiles on a rotary launcher fitted in the bomb-bay. To conform with SALT II Treaty requirements that cruise missile-capable aircraft be readily identifiable by reconnaissance satellites, the cruise missile armed B-52Gs were modified with a distinctive wing root fairing. As all B-52Hs were assumed modified, no visual modification of these aircraft was required.[94] In 1990, the stealthy AGM-129 ACM cruise missile entered service; although intended to replace the AGM-86, a high cost and the Cold War's end led to only 450 being produced; unlike the AGM-86, no conventional (non-nuclear) version was built.[95] The B-52 was to have been modified to utilize Northrop Grumman's AGM-137 TSSAM weapon; however, the missile was canceled due to development costs.[96]

Those B-52Gs not converted as cruise missile carriers underwent a series of modifications to improve conventional bombing. They were fitted with a new Integrated Conventional Stores Management System (ICSMS) and new underwing pylons that could hold larger bombs or other stores than could the external pylons. Thirty B-52s were further modified to carry up to 12 AGM-84 Harpoon anti-ship missiles each, while 12 B-52Gs were fitted to carry the AGM-142 Have Nap stand-off air-to-ground missile.[97] When the B-52G was retired in 1994, an urgent scheme was launched to restore an interim Harpoon and Have Nap capability,[Note 4] the four aircraft being modified to carry Harpoon and four to carry Have Nap under the Rapid Eight program.[100]

The Conventional Enhancement Modification (CEM) program gave the B-52H a more comprehensive conventional weapons capability, adding the modified underwing weapon pylons used by conventional-armed B-52Gs, Harpoon and Have Nap, and the capability to carry new-generation weapons including the Joint Direct Attack Munition and Wind Corrected Munitions Dispenser guided bombs, the AGM-154 glide bomb and the AGM-158 JASSM missile. The CEM program also introduced new radios, integrated Global Positioning System into the aircraft's navigation system and replaced the under-nose FLIR with a more modern unit. Forty-seven B-52Hs were modified under the CEM program by 1996, with 19 more by the end of 1999.[101][102]

Starting in 2016, Boeing is to upgrade the internal rotary launchers to the MIL-STD-1760 interface to enable the internal carriage of smart bombs, which can currently only be carried on the wings.[103]

USAF B-52H Stratofortress Engines

For a study for the U.S. Air Force in the mid-1970s, Boeing investigated replacing the engines, changing to a new wing, and other improvements to upgrade B-52G/H aircraft as an alternative to the B-1A, then in development.[104] Boeing later suggested re-engining the B-52H fleet with the Rolls-Royce RB211 535E-4.[105] This would involve replacing the eight Pratt & Whitney TF33s (total thrust 8 × 17,000 lb) with four RB211s (total thrust 4 × 37,400 lb)—which would increase range and reduce fuel consumption, at a cost of approximately US$2.56 billion for the whole fleet (71 aircraft at $36 million each). A Government Accountability Office study concluded that Boeing's estimated savings of US$4.7 billion would not be realized and that it would cost US$1.3 billion over keeping the existing engines, citing significant up-front procurement and re-tooling expenditure, as well as the RB211's higher maintenance cost. The GAO report was subsequently disputed in a Defense Sciences Board report in 2003; the Air Force was urged to re-engine the aircraft without delay.[106] Further, the DSB report stated the program would have significant savings, reduce greenhouse gas emissions, and increase aircraft range and endurance, in line with the conclusions of a separate Congress-funded study conducted in 2003.[107] In 2014, the U.S. Air Force was reviewing industry studies of engine replacement.[108] The re-engining has not been approved as of 2014. In late 2014, it was reported that the DOD and unnamed private companies were exploring a leasing program where private lease companies would purchase new engines and lease them to the USAF. DOD costs would be determined by depreciation and actual usage with no up-front lump payments.[109]

Operational history


Although the B-52A was the first production variant, these aircraft were used only in testing. The first operational version was the B-52B that had been developed in parallel with the prototypes since 1951. First flying in December 1954, B-52B, AF Serial Number 52-8711, entered operational service with 93rd Heavy Bombardment Wing (93rd BW) at Castle Air Force Base, California, on 29 June 1955. The wing became operational on 12 March 1956. The training for B-52 crews consisted of five weeks of ground school and four weeks of flying, accumulating 35 to 50 hours in the air. The new B-52Bs replaced operational B-36s on a one-to-one basis.[111]

Early operations were problematic;[112] in addition to supply problems, technical issues also struck.[113] Ramps and taxiways deteriorated under the aircraft's weight, the fuel system was prone to leaks and icing,[114] and bombing and fire control computers were unreliable.[113] The split level cockpit presented a temperature control problem – the pilots' cockpit was heated by sunlight while the observer and the navigator on the bottom deck sat on the ice-cold floor. Thus, a comfortable temperature setting for the pilots caused the other crew members to freeze, while a comfortable temperature for the bottom crew caused the pilots to overheat.[115] The J57 engines proved unreliable. Alternator failure caused the first fatal B-52 crash in February 1956;[116] as a result the fleet was briefly grounded. In July, fuel and hydraulic issues grounded the B-52s again. In response to maintenance issues, the air force set up "Sky Speed" teams of 50 contractors at each B-52 base to perform maintenance and routine checkups, taking an average of one week per aircraft.[117]

Three B-52Bs of the 93rd Bomb Wing prepare to depart March AFB for Castle AFB, California, after their record-setting round-the-world flight in 1957.

On 21 May 1956, a B-52B (52-0013) dropped a Mk-15 nuclear bomb over the Bikini Atoll in a test code-named Cherokee. It was the first air-dropped thermonuclear weapon.[118] From 24 to 25 November 1956, four B-52Bs of the 93rd BW and four B-52Cs of the 42nd BW flew nonstop around the perimeter of North America in Operation Quick Kick, which covered 15,530 miles (13,500 nmi, 25,000 km) in 31 hours, 30 minutes. SAC noted the flight time could have been reduced by 5 to 6 hours if the four inflight refuelings were done by fast jet-powered tanker aircraft rather than propeller-driven Boeing KC-97 Stratofreighters.[119] In a demonstration of the B-52's global reach, from 16 to 18 January 1957, three B-52Bs made a non-stop flight around the world during Operation Power Flite, during which 24,325 miles (21,145 nmi, 39,165 km) was covered in 45 hours 19 minutes (536.8 smph) with several in-flight refuelings by KC-97s.[120][Note 5]

The B-52 set many records over the next few years. On 26 September 1958, a B-52D set a world speed record of 560.705 miles per hour (487 kn, 902 km/h) over a 10,000 kilometers (5,400 nmi, 6,210 mi) closed circuit without a payload. The same day, another B-52D established a world speed record of 597.675 miles per hour (519 kn, 962 km/h) over a 5,000 kilometer (2,700 nmi, 3,105 mi) closed circuit without a payload.[80] On 14 December 1960, a B-52G set a world distance record by flying unrefueled for 10,078.84 miles (8,762 nmi, 16,227 km); the flight lasted 19 hours 44 minutes (510.75 mph).[121] From 10 to 11 January 1962, a B-52H set a world distance record by flying unrefueled, surpassing the prior B-52 record set two years earlier, from Kadena Air Base, Okinawa, Japan, to Torrejon Air Base, Spain, which covered 12,532.28 miles (10,895 nmi, 20,177 km).[61] The flight passed over Seattle, Fort Worth and the Azores.

Cold War

Main article: Cold War

When the B-52 entered into service, the Strategic Air Command (SAC) intended to use it to deter and counteract the vast and modernizing Soviet military. As the Soviet Union increased its nuclear capabilities, destroying or "countering" the forces that would deliver nuclear strikes (bombers, missiles, etc.) became of great strategic importance.[122] The Eisenhower administration endorsed this switch in focus; the President in 1954 expressing a preference for military targets over those of civilian ones, a principle reinforced in the Single Integrated Operation Plan (SIOP), a plan of action in the case of nuclear war breaking out.[123]

Southerly route of the "Operation Chrome Dome" airborne nuclear alert

Throughout the Cold War, B-52s and other US strategic bombers performed airborne alert patrols under code names such as Head Start, Chrome Dome, Hard Head, Round Robin, and Giant Lance. Bombers loitered at high altitude near the borders of the Soviet Union to provide rapid first strike or retaliation capability in case of nuclear war.[124] These airborne patrols formed one component of the US's nuclear deterrent, which would act to prevent the breakout of a large-scale war between the US and the Soviet Union under the concept of Mutually Assured Destruction.[125]

Due to the late 1950s-era threat of surface-to-air missiles (SAMs) that could threaten high-altitude aircraft,[126][127] seen in practice in the 1960 U-2 incident,[128] the intended use of B-52 was changed to serve as a low-level penetration bomber during a foreseen attack upon the Soviet Union, as terrain masking provided an effective method of avoiding radar and thus the threat of the SAMs.[129] Although never intended for the low level role, the B-52's flexibility allowed it to outlast several intended successors as the nature of aerial warfare changed. The B-52's large airframe enabled the addition of multiple design improvements, new equipment, and other adaptations over its service life.[85]

In November 1959, to improve the aircraft's combat capabilities in the changing strategic environment, SAC initiated the Big Four modification program (also known as Modification 1000) for all operational B-52s except early B models.[78][129] The program was completed by 1963.[130] The four modifications were the ability to launch AGM-28 Hound Dog standoff nuclear missiles and ADM-20 Quail decoys, an advanced electronic countermeasures (ECM) suite, and upgrades to perform the all-weather, low-altitude (below 500 feet or 150 m) interdiction mission in the face of advancing Soviet missile-based air defenses.[130]

In the 1960s, there were concerns over the fleet's capable lifespan. Several projects beyond the B-52, the Convair B-58 Hustler and North American XB-70 Valkyrie, had either been aborted or proved disappointing in light of changing requirements, which left the older B-52 as the main bomber as opposed to the planned successive aircraft models.[131][132] On 19 February 1965, General Curtis E. LeMay testified to Congress that the lack of a follow-up bomber project to the B-52 raised the danger that, "The B-52 is going to fall apart on us before we can get a replacement for it."[133] Other aircraft, such as the General Dynamics F-111 Aardvark, later complemented the B-52 in roles the aircraft was not as capable in, such as missions involving high-speed, low-level penetration dashes.[134]

With the escalating situation in Southeast Asia, 28 B-52Fs were fitted with external racks for 24x 750 pound (340 kg) bombs under project South Bay in June 1964; an additional 46 aircraft received similar modifications under project Sun Bath.[70] In March 1965, the United States commenced Operation Rolling Thunder. The first combat mission, Operation Arc Light, was flown by B-52Fs on 18 June 1965, when 30 bombers of the 9th and 441st Bombardment Squadrons struck a communist stronghold near the Bến Cát District in South Vietnam. The first wave of bombers arrived too early at a designated rendezvous point, and while maneuvering to maintain station, two B-52s collided, which resulted in the loss of both bombers and eight crewmen. The remaining bombers, minus one more that turned back due to mechanical problems, continued toward the target.[135] Twenty-seven Stratofortresses dropped on a one-mile by two-mile target box from between 19,000 and 22,000 feet, a little more than 50% of the bombs falling within the target zone.[136] The force returned to Andersen AFB except for one bomber with electrical problems that recovered to Clark AFB, the mission having lasted 13 hours. Post-strike assessment by teams of South Vietnamese troops with American advisors found evidence that the VC had departed the area before the raid, and it was suspected that infiltration of the south's forces may have tipped off the north because of the ARVN troops involved in the post-strike inspection.[137]

Beginning in late 1965, a number of B-52Ds underwent Big Belly modifications to increase bomb capacity for carpet bombings.[138] While the external payload remained at 24 500 pound (227 kg) or 750 pound (340 kg) bombs, the internal capacity increased from 27 to 84 500 pound bombs or from 27 to 42 750 pound bombs.[139] The modification created enough capacity for a total of 60,000 pounds (27,215 kg) in 108 bombs. Thus modified, B-52Ds could carry 22,000 pounds (9,980 kg) more than B-52Fs.[140] Designed to replace B-52Fs, modified B-52Ds entered combat in April 1966 flying from Andersen Air Force Base, Guam. Each bombing mission lasted 10 to 12 hours with an aerial refueling by KC-135 Stratotankers.[49] In spring 1967, the aircraft began flying from U Tapao Airfield in Thailand giving the aircraft the advantage of not requiring in-flight refueling.[139]

The B-52s were restricted to bombing suspected Communist bases in relatively uninhabited sections, because their potency approached that of a tactical nuclear weapon. A formation of six B-52s, dropping their bombs from 30,000 feet, could "take out"... almost everything within a "box" approximately five-eights mile wide by two miles long. Whenever Arc Light struck ... in the vicinity of Saigon, the city woke from the tremor..

Neil Sheehan, war correspondent, writing before the mass attacks to heavily populated cities including North Vietnam's capital.[141]

On 22 November 1972, a B-52D (55-0110) from U-Tapao was hit by a surface-to-air missile (SAM) while on a raid over Vinh. The crew was forced to abandon the damaged aircraft over Thailand. This was the first B-52 destroyed by hostile fire.[142] In total, 31 B-52s were lost during the war, which included 10 B-52s shot down over North Vietnam.[143]

The zenith of B-52 attacks in Vietnam was Operation Linebacker II (sometimes referred to as the Christmas Bombing) which consisted of waves of B-52s (mostly D models, but some Gs without jamming equipment and with a smaller bomb load). Over 12 days, B-52s flew 729 sorties[144] and dropped 15,237 tons of bombs on Hanoi, Haiphong, and other targets.[87][145] Originally 42 B-52s were committed to the war; however, numbers were frequently twice this figure.[146] During Operation Linebacker II, fifteen B-52s were shot down, five were heavily damaged (one crashed in Laos), and five suffered medium damage. A total of 25 crewmen were killed in these losses.[147] North Vietnam claimed 34 B-52s were shot down.[148]

Air-to-air victories

During the Vietnam War, B-52D tail gunners were credited with shooting down two MiG-21 "Fishbeds". On 18 December 1972, tail gunner Staff Sergeant Samuel O. Turner's B-52 had just completed a bomb run for Operation Linebacker II and was turning away when a North Vietnamese Air Force MiG-21 approached.[169] The MiG and the B-52 locked onto one another. When the fighter drew within range, Turner fired his quad (four guns on one mounting) .50 caliber machine guns.[170] The MiG exploded aft of the bomber,[169] a victory confirmed by Master Sergeant Louis E. Le Blanc, the tail gunner in a nearby Stratofortress. Turner received a Silver Star for his actions.[171] His B-52, tail number 55-0676, is preserved on display with air-to-air kill markings at Fairchild AFB in Spokane, Washington.[169]

On 24 December 1972, during the same bombing campaign, the B-52 Diamond Lil was headed to bomb the Thái Nguyên railroad yards when tail gunner Airman First Class Albert E. Moore spotted a fast-approaching MiG-21.[172] Moore opened fire with his quad fifties at Script error: No such module "convert"., and kept shooting until the fighter disappeared from his scope. Technical Sergeant Clarence W. Chute, a tail gunner aboard another Stratofortress, watched the MiG catch fire and fall away. The Diamond Lil is preserved on display at the United States Air Force Academy in Colorado.[172] Moore was the last recorded bomber gunner to shoot down an enemy aircraft with machine guns in aerial combat.[170] However, these air-to-air kills were not confirmed by VPAF.[173]

Vietnamese sources have attributed a third air-to-air victory to a B-52, a MiG-21 shot down on 16 April 1972.[174] These victories make the B-52 the largest aircraft credited with air-to-air kills.[Note 6] The last Arc Light mission without fighter escort took place on 15 August 1973, as U.S. military action in Southeast Asia was wound down.[175]

Post Vietnam service

B-52Bs reached the end of their structural service life by the mid-1960s and all were retired by June 1966, followed by the last of the B-52Cs on 29 September 1971; except for NASA's B-52B "008" which was eventually retired in 2004 at Edwards AFB, California.[176] Another of the remaining B Models, "005" is on display at the Wings Over the Rockies Air and Space Museum in Denver, Colorado.[177]

A few time-expired E models were retired in 1967 and 1968, but the bulk (82) were retired between May 1969 and March 1970. Most F models were also retired between 1967 and 1973, but 23 survived as trainers until late 1978. The fleet of D models served much longer; 80 D models were extensively overhauled under the Pacer Plank program during the mid-1970s.[178] Skinning on the lower wing and fuselage was replaced, and various structural components were renewed. The fleet of D models stayed largely intact until late 1978, when 37 not already upgraded Ds were retired.[179] The remainder were retired between 1982 and 1983.[180]

The remaining G and H models were used for nuclear standby ("alert") duty as part of the United States' nuclear triad. This triad was the combination of nuclear-armed land-based missiles, submarine-based missiles and manned bombers. The B-1, intended to supplant the B-52, replaced only the older models and the supersonic FB-111.[181] In 1991, B-52s ceased continuous 24-hour SAC alert duty.[182]

After the fall of the Soviet Union, all B-52Gs remaining in service were destroyed per the terms of the Strategic Arms Reduction Treaty (START). The Aerospace Maintenance and Regeneraton Center (AMRC) cut the 365 B-52G bombers into pieces. Completion of the destruction task was verified by Russia via satellite and first-person inspection at the AMARC facility.[183]

Gulf War and later

See also: Gulf War
Retired B-52s are stored at the 309th AMARG (formerly AMARC), a desert storage facility often called the "Boneyard" at Davis-Monthan AFB near Tucson, Arizona.[184]

B-52 strikes were an important part of Operation Desert Storm. Starting on 16 January 1991, a flight of B-52Gs flew from Barksdale AFB, Louisiana, refueled in the air en route, struck targets in Iraq, and returned home – a journey of 35 hours and 14,000 miles round trip. It set a record for longest-distance combat mission, breaking the record previously held by an RAF Vulcan bomber in 1982; however, this was achieved using forward refueling.[185][186] B-52Gs operating from the King Abdullah Air Base at Jeddah, Saudi Arabia; RAF Fairford in the United Kingdom; Morón Air Base, Spain; and the island of Diego Garcia in the British Indian Ocean Territory flew bombing missions over Iraq, initially at low altitude. After the first three nights, the B-52s moved to high-altitude missions instead, which reduced their effectiveness and psychological impact compared to the low altitude role initially played.[187]

The conventional strikes were carried out by three bombers, which dropped up to 153 750-pound bombs over an area of Script error: No such module "convert".. The bombings demoralized the defending Iraqi troops, many of whom surrendered in the wake of the strikes.[188] In 1999, the science and technology magazine Popular Mechanics described the B-52's role in the conflict: "The Buff's value was made clear during the Gulf War and Desert Fox. The B-52 turned out the lights in Baghdad."[189] During Operation Desert Storm, B-52s flew about 1,620 sorties, and delivered 40% of the weapons dropped by coalition forces.[3]

During the conflict, several claims of Iraqi air-to-air successes were made, including an Iraqi pilot, Khudai Hijab, who allegedly fired a Vympel R-27R missile from his MIG-29 and damaged a B-52G on the opening night of the Gulf War.[190] However, the U.S. Air Force disputes this claim, stating the bomber was actually hit by friendly fire, an AGM-88 High-speed, Anti-Radiation Missile (HARM) that homed on the fire-control radar of the B-52's tail gun; the jet was subsequently renamed In HARM's Way.[191] Shortly following this incident, General George Lee Butler announced that the gunner position on B-52 crews would be eliminated, and the gun turrets permanently deactivated, commencing on 1 October 1991.[192]

From 2 to 3 September 1996, two B-52H bombers conducted a mission as part of Operation Desert Strike. The B-52s struck Baghdad power stations and communications facilities with 13 AGM-86C conventional air-launched cruise missiles (CALCM) during a 34-hour, 16,000-mile round trip mission from Andersen AFB, Guam – the longest distance ever flown for a combat mission.[193]

Since the mid-1990s, the B-52H has been the only variant remaining in military service;[Note 7] it is currently stationed at:

On 24 March 1999, when Operation Allied Force began, B-52 bombers bombarded Serb targets throughout the Federal Republic of Yugoslavia, including during the Battle of Kosare.[195]

The B-52 contributed to Operation Enduring Freedom in 2001 (Afghanistan/Southwest Asia), providing the ability to loiter high above the battlefield and provide Close Air Support (CAS) through the use of precision guided munitions, a mission which previously would have been restricted to fighter and ground attack aircraft.[196] In late 2001, ten B-52s dropped a third of the bomb tonnage in Afghanistan.[197] B-52s also played a role in Operation Iraqi Freedom, which commenced on 20 March 2003 (Iraq/Southwest Asia). On the night of 21 March 2003, B-52Hs launched at least one hundred AGM-86C CALCMs at targets within Iraq.[198]

In August 2007, a B-52H ferrying AGM-129 ACM cruise missiles from Minot Air Force Base to Barksdale Air Force Base for dismantling was mistakenly loaded with six missiles with their nuclear warheads. The weapons did not leave USAF custody and were secured at Barksdale.[199][200]

As of January 2013, 78 of the original 744 B-52 aircraft were operational in the U.S. Air Force.[201] Four of 18 B-52Hs from Barksdale AFB being retired are in the "boneyard" of 309th AMARG at Davis-Monthan AFB as of 8 September 2008.[202]

Continued service

B-52s are periodically refurbished at USAF maintenance depots such as Tinker Air Force Base, Oklahoma.[203] Even while the air force works on its Next-Generation Bomber and 2037 Bomber projects, it intends to keep the B-52H in service until 2045, nearly 90 years after the B-52 first entered service, an unprecedented length of service for any aircraft, civilian or military.[3][204][205][Note 8] The USAF continues to rely on the B-52 because it remains an effective and economical heavy bomber, particularly in the type of missions that have been conducted since the end of the Cold War against nations that have limited air defense capabilities. The B-52 has the capacity to "loiter" for extended periods over (or even well outside) the battlefield, and deliver precision standoff and direct fire munitions. It has been a valuable asset in supporting ground operations during conflicts such as Operation Iraqi Freedom.[207] The B-52 had the highest mission capable rate of the three types of heavy bombers operated by the USAF in 2001. The B-1 averaged a 53.7% ready rate and the Northrop Grumman B-2 Spirit achieved 30.3%, while the B-52 averaged 80.5% during the 2000–2001 period.[184] The B-52's $72,000 cost per hour of flight is more than the B-1B's $63,000 cost per hour, but less than the B-2's $135,000 per hour.[208]

Additionally, a proposed variant of the B-52H was the EB-52. This version would have modified and augmented 16 B-52H airframes with additional electronic jamming capabilities.[209][210] This new aircraft would have given the USAF an airborne jamming capability that it has lacked since retiring the EF-111 Raven. The program was canceled in 2005 following the removal of funds for the stand-off jammer. The program was revived in 2007, but funding was again cut in early 2009.[211]

In 2012, it was announced that USAF engineering studies suggest that the lifespan of the B-52 could extend beyond 2040.[212]

In July 2013, the Air Force began a fleet-wide technological upgrade of its B-52 bombers called Combat Network Communications Technology (CONECT) to modernize electronics, communications technology, computing, and avionics on the flight deck. CONECT upgrades include software and hardware such as new servers, modems, radios, data-links, receivers, and digital workstations for the crew. One piece is the ARC-210 Warrior beyond-line-of-sight software programmable radio able to transmit voice, data, and information in-flight between B-52s and ground command and control centers, allowing for the transmission and receipt of data with updated intelligence, mapping, or targeting information; previous in-flight target changes required copying down coordinates, while the ARC-210 allows machine-to-machine transfer of data, useful on long-endurance missions where targets may have changed locations when the B-52 was traveling. The aircraft will be able to receive information through Link-16. CONECT upgrades will cost $1.1 billion overall and take several years. Funding has been secured for 30 B-52s and the Air Force hopes for 10 CONECT upgrades per year, but the rate has yet to be determined.[213]

Weapons upgrades include the 1760 Internal Weapons Bay Upgrade (IWBU), which gives a 66 percent increase in carriage capability using a digital interface and rotary launcher to increase the weapons payload. The IWBU effort is expected to cost roughly $313 million.[213] The 1760 IWBU will allow the B-52 to carry the AGM-158B JASSM-ER and the ADM-160C MALD-J. All 1760 IWBUs should be online by October 2017. As opposed to three B-52s carrying 36 weapons, two bombers will have the ability to carry 40 weapons, lowering the number of crews and amounts of fuel needed for a mission, and gives the option of putting more weapons on target with the same number of aircraft.[214] The 1760 IWBU allows precision-guided weapons to be deployed from inside the weapons bay, increasing the number of guided weapons a B-52 can carry and reducing the need for guided bombs to be carried externally on wing hardpoints. The first phase will allow a B-52 to carry 24 500-pound JDAMs or 20 2,000-pound JDAMs, with later phases accommodating the JASSM and MALD family of missiles.[215] In addition to carrying more smart bombs, moving them internally from the wings results in a 15 percent fuel savings and greater range from less drag.[216]

The Long Range Strike Bomber program is expected to yield a stealthy B-52 and B-1 successor that would begin service in the 2020s. Two competitors, Northrop Grumman and a joint team of Boeing and Lockheed Martin, submitted proposals in 2014. A contract to the winning team will be awarded in mid-2015. About 80–100 aircraft will be produced.[217]

The B-52 went through several design changes and variants over its 10 years of production.[110]

Two prototype aircraft with limited operational equipment, used for aerodynamic and handling tests
One XB-52 modified with some operational equipment and re-designated
Only three of the first production version, the B-52A, were built, all loaned to Boeing for flight testing.[49] The first production B-52A differed from prototypes in having a redesigned forward fuselage. The bubble canopy and tandem seating was replaced by a side-by-side arrangement and a Script error: No such module "convert". nose extension accommodated more avionics and a new sixth crew member.[Note 9] In the rear fuselage, a tail turret with four 0.50 inch (12.7 mm) machine guns with a fire-control system, and a water injection system to augment engine power with a 360 US gallon (1,363 L) water tank were added. The aircraft also carried a 1,000 US gallon (3,785 L) external fuel tank under each wing. The tanks damped wing flutter and also kept wingtips close to the ground for ease of maintenance.[218]

The last B-52A (serial 52-0003) was modified and redesignated NB-52A in 1959 to carry the North American X-15. A pylon was fitted under the right wing between the fuselage and the inboard engines with a 6 feet x 8 feet (1.8 m x 2.4 m) section removed from the right wing flap to fit the X-15 tail. Liquid oxygen and hydrogen peroxide tanks were installed in the bomb bays to fuel the X-15 before launch. Its first flight with the X-15 was on 19 March 1959, with the first launch on 8 June 1959. The NB-52A, named "The High and Mighty One" carried the X-15 on 93 of the program's 199 flights.[219]
NASA's NB-52B Balls 8 (lower) and its replacement B-52H on the flight line at Edwards Air Force Base in 2004

The B-52B was the first version to enter service with the USAF on 29 June 1955 with the 93rd Bombardment Wing at Castle AFB in California.[218] This version included minor changes to engines and avionics, enabling an extra 12,000 pounds of thrust using water injection.[220] Temporary grounding of the aircraft after a crash in February 1956 and again the following July caused training delays, and at mid-year there were still no combat-ready B-52 crews.[116]

Of the 50 B-52Bs built, 27 were capable of carrying a reconnaissance pod as RB-52Bs (the crew was increased to eight in these aircraft).[49] The 300 pound (136 kg) pod contained radio receivers, a combination of K-36, K-38, and T-11 cameras, and two operators on downward-firing ejection seats. The pod required only four hours to install.[116]
Seven B-52Bs were brought to B-52C standard under Project Sunflower.[221]
The NB-52B was B-52B number 52-0008 converted to an X-15 launch platform. It subsequently flew as the "Balls 8" in support of NASA research until 17 December 2004, making it the oldest flying B-52B. It was replaced by a modified B-52H.[222]
The B-52C's fuel capacity (and range) was increased to 41,700 US gallons by adding larger 3000 US gallon underwing fuel tanks. The gross weight was increased by 30,000 pounds (13,605 kg) to 450,000 pounds. A new fire control system, the MD-9, was introduced on this model.[141] The belly of the aircraft was painted with antiflash white paint, which was intended to reflect thermal radiation away after a nuclear detonation.[223]
The RB-52C was the designation initially given to B-52Cs fitted for reconnaissance duties in a similar manner to RB-52Bs. As all 35 B-52Cs could be fitted with the reconnaissance pod, the RB-52C designation was little used and was quickly abandoned.[223]
File:B-52D dropping bombs.jpg
B-52D dropping 500-lb bombs
The B-52D was a dedicated long-range bomber without a reconnaissance option. The Big Belly modifications allowed the B-52D to carry heavy loads of conventional bombs for carpet bombing over Vietnam,[220] while the Rivet Rambler modification added the Phase V ECM systems, which was better than the systems used on most later B-52s. Because of these upgrades and its long range capabilities, the D model was used more extensively in Vietnam than any other model.[141] Aircraft assigned to Vietnam were painted in a camouflage colour scheme with black bellies to defeat searchlights.[68]
The B-52E received an updated avionics and bombing navigational system, which was eventually debugged and included on following models.[220]
One E aircraft (AF Serial No. 56-0631) was modified as a testbed for various B-52 systems. Redesignated NB-52E, the aircraft was fitted with canards and a Load Alleviation and Mode Stabilization system (LAMS) which reduced airframe fatigue from wind gusts during low level flight. In one test, the aircraft flew 10 knots (11.5 mph, 18.5 km/h) faster than the never exceed speed without damage because the canards eliminated 30% of vertical and 50% of horizontal vibrations caused by wind gusts.[224]
This aircraft was given J57-P-43W engines with a larger capacity water injection system to provide greater thrust than previous models.[220] This model had problems with fuel leaks which were eventually solved by several service modifications: Blue Band, Hard Shell, and QuickClip.[82]
B-52G on static display at Langley Air Force Base in Hampton, Virginia
The B-52G was proposed to extend the B-52's service life during delays in the B-58 Hustler program. At first, a radical redesign was envisioned with a completely new wing and Pratt & Whitney J75 engines. This was rejected to avoid slowdowns in production, although a large number of changes were implemented.[220] The most significant of these was the brand-new "wet" wing with integral fuel tanks which considerably increased the fuel capacity; gross aircraft weight went up by 38,000 pounds (17,235 kg) compared with prior variants. In addition, a pair of 700 US gallon (2,650 L) external fuel tanks was fitted under the wings.[225] In this model, the traditional ailerons were eliminated. Instead, spoilers provided roll control. The tail fin was shortened by 8 feet (2.4 m), water injection system capacity was increased to 1,200 US gallons (4,540 L), and the nose radome was enlarged.[226] The tail gunner manning the 4 .50 caliber machine guns (quad mounted in a remote controlled tail turret on the G-model (ASG-15), the guns were later removed from all operational aircraft) was relocated to the main cockpit and was provided with an ejection seat.[225] Dubbed the "Battle Station" concept, the offensive crew (pilot and copilot on the upper deck and the two bombing navigation system operators on the lower deck) faced forward, while the defensive crew (tail gunner and ECM operator) on the upper deck faced aft.[141] The B-52G entered service on 13 February 1959 (a day earlier, the last B-36 was retired, making SAC an all-jet bomber force). 193 B-52Gs were produced, making this the most produced B-52 variant. Most B-52Gs were destroyed in compliance with the 1992 Strategic Arms Reduction Treaty; the last B-52G, number 58-0224, was dismantled under New START treaty requirements in December 2013.[227] A few examples remain on display for museums.[228]
The B-52H had the same crew and structural changes as the B-52G. The most significant upgrade was the switch to TF33-P-3 turbofan engines which, despite the initial reliability problems (corrected by 1964 under the Hot Fan program), offered considerably better performance and fuel economy than the J57 turbojets.[141][226] The ECM and avionics were updated, a new fire control system was fitted, and the rear defensive armament was changed from machine guns to a 20 mm M61 Vulcan cannon (later removed in 1991–94).[225] The final 18 aircraft were manufactured with provision for the ADR-8 countermeasures rocket, which was later retrofitted to the remainder of the B-52G and B-52H fleet.[229] A provision was made for four GAM-87 Skybolt ballistic missiles. The aircraft's first flight occurred on 10 July 1960, and it entered service on 9 May 1961. This is the only variant still operational. A total of 102 B-52Hs were built. The last production aircraft, B-52H AF Serial No. 61-0040, left the factory on 26 October 1962.[230]
Allocated to the reconnaissance variant of the B-52B but not used and the aircraft were designated RB-52B instead.[231]

Notable accidents

  • On 10 January 1957, a B-52 returning to Loring Air Force Base from a routine instrument training mission broke apart in midair and crashed near Morrell, New Brunswick, killing eight of the nine crew on board. Co-pilot Captain Joseph L. Church parachuted to safety. The crash was believed to have been caused by overstressing the wings and/or airframe during an exercise designed to test the pilot's reflexes. This was the fourth crash involving a B-52 in 11 months.[232]
  • On 11 February 1958, a B-52D crashed in South Dakota because of ice blocking the fuel system, leading to an uncommanded reduction in power to all eight engines. Three crew members were killed.[233]
  • On 8 September 1958, two B-52s collided in midair near Fairchild AFB, Washington; all 13 crew members on the 2 aircraft are killed [234]
  • On 15 October 1959, a B-52 from the 492d Bomb Squadron at Columbus AFB, Mississippi carrying 2 nuclear weapons collided in midair with a KC-135 tanker near Hardinsburg, Kentucky; 4 of the 8 crew members on the bomber and all 4 crew on the tanker were killed. One of the nuclear bombs was damaged by fire but both weapons were recovered.[234]
  • On 10 August 1959, a B-52 crashed in the Spruce Swamp at Fremont, New Hampshire. The bomber was on a routine training mission from Chicopee, Mass., when its air speed indicator and altimeter failed, which led to more serious malfunctions. The B-52 was attempting to make an emergency landing at Goose Bay, the only landing option not affected by foggy weather conditions. However, it crashed before making the landing. The U.S. Air Force reported that it was the first B-52 crash where the entire crew survived; the crew parachuted to safety. Debris from the crash covered a quarter-mile of densely wooded swampland.[235]

MK 39 nuclear bomb after the January 1961 Goldsboro B-52 crash. The weapon's parachute deployed, resulting in a soft landing and recovery of the weapon intact. Five of the six stages of the arming sequence had completed.
  • On 24 January 1961, a B-52G broke up in midair and crashed after suffering a severe fuel loss, near Goldsboro, North Carolina, dropping two nuclear bombs in the process without detonation.[236]
  • On 14 March 1961, a B-52F from Mather AFB[237] carrying two nuclear weapons experienced an uncontrolled decompression, necessitating a descent to 10,000 feet to lower the cabin altitude. Increased fuel consumption at the lower altitude and unable to rendezvous with a tanker in time, the aircraft ran out of fuel. The crew ejected safely, while the unmanned bomber crashed Script error: No such module "convert". west of Yuba City, California.[238]
  • On 7 April 1961, B-52B (53-0380) was accidentally shot down by a New Mexico Air National Guard F-100 on an intercept training mission. The F-100 was carrying live missiles whose launch capability was supposed to be disabled, but a wiring fault caused one of them to fire and strike the bomber's left wing. The aircraft crashed near Mount Taylor, killing three of the eight crew members on board.[239][better source needed]
  • On 24 January 1963, a B-52C on a training mission out of Westover Air Force Base, Massachusetts, lost its vertical stabilizer due to buffeting during low-level flight, and crashed on the west side of Elephant Mountain near Greenville, Maine. Of the nine crewmen aboard, two survived the crash.[240][241]
  • On 30 January 1963, a B-52E of the 6th Bomb Wing from Walker Air Force Base, New Mexico, crashed in snow-covered mountains in northern New Mexico after turbulence tore off the vertical fin. The ECM operator and tail gunner were killed but at least three crew (pilot, radio operator and one other crew member) survived. Three Lockheed T-33 Shooting Stars and, later, three Douglas C-54 Skymaster transports, circled the area trying to locate survivors; the pilots reported that they saw two other survivors after the first man walked to safety.
  • On 10 January 1964, a B-52H flown by Boeing test pilots lost its vertical stabilizer to turbulence near East Spanish Peak. It was able to land at Blytheville Air Force Base.[242][243]
  • On 13 January 1964, a B-52D carrying two nuclear bombs suffered a structural failure in flight that caused the tail section to shear off. Four crewmen ejected successfully before the aircraft crashed near Cumberland, Maryland.[244] Two crewmen subsequently perished on the ground because of hypothermia, while another, who was unable to eject, died in the aircraft; both weapons were recovered. This was one of several incidents caused by failure of the vertical stabilizer.[245]
  • On 17 January 1966, a fatal collision occurred between a B-52G and a KC-135 Stratotanker over Palomares, Spain. The two unexploded B-28 FI 1.45-megaton-range nuclear bombs on the B-52 were eventually recovered; the conventional explosives of two more bombs detonated on impact, with serious dispersion of both plutonium and uranium, but without triggering a nuclear explosion. After the crash, Script error: No such module "convert". of contaminated soil was sent to the United States.[246] In 2006, an agreement was made between the U.S. and Spain to investigate and clean the pollution still remaining as a result of the accident.[247]
  • On 18 November 1966, a B-52G Serial No. 58-0228 deployed from Barksdale Air Force Base crashed and was destroyed when it flew into the ground in swampland south of Stone Lake, Sawyer County, Wisconsin. The crew was on a low level terrain avoidance night mission, before SAC stopped such flights, and had just entered low altitude and were calibrating their terrain avoidance radar, when they flew too low, clipped the tops of the forest and crashed.[248][249]
  • On 8 July 1967, B-52D AF Serial No. 56-0601 overran the runway due to loss of brakes during an emergency landing at Da Nang Air Base, Vietnam with the loss of five of her six crew. The aircraft had suffered an electrical malfunction that led to the flameout of two engines.[250]
  • On 21 January 1968, a B-52G, with four nuclear bombs aboard as part of Operation Chrome Dome, crashed on the ice of the North Star Bay while attempting an emergency landing at Thule Air Base, Greenland.[251] The resulting fire caused extensive radioactive contamination, the cleanup (Project Crested Ice) lasting until September of that year.[246] Following closely on the Palomares incident, the cleanup costs and political consequences proved too high to risk again, so SAC ended the airborne alert program the following day.[252][253]
  • On 3 April 1970 a B-52D assigned to the 28th Bomb Wing caught fire and crashed while landing at Ellsworth AFB, South Dakota; sliding to a halt and burning atop a 25,000 gallon fuel storage tank. Efforts by fire department personnel saved the 9 man crew and prevented a catastrophic explosion of the fuel tank.[234]
  • On 31 March 1972, B-52D, AF Serial No. 56-0625, departed McCoy Air Force Base, Florida on a routine training mission. Assigned to the 306th Bombardment Wing, the unarmed aircraft sustained multiple engine failures and engine fires on engines No.7 and No.8 shortly after takeoff. The aircraft immediately attempted to return to the base, but crashed just short of Runway 18R in a residential area of Orlando, Florida, approximately 1 mile north of McCoy AFB, destroying or damaging eight homes. The flight crew of 7 airmen and 1 civilian on the ground were killed.[254]
  • On 30 July 1972, B-52D, AF Serial No. 56-0677, assigned to the 307th Strategic Bomb Wing, operating out of U-Tapao Royal Thai Navy Airfield on a combat mission as part of Operation Linebacker was hit by lightning. The strike knocked out the plane's instruments and started a fire on the port wing. Five of the six crewmen were killed in the crash[255]
  • On 30 October 1981, B-52D, AF Serial No. 55-078, assigned to the 22d Bomb Wing, March AFB, CA, impacted the ground nine miles east of La Junta, CO during a night low-level training mission. All eight crew members on board were killed (six crew and two maintainers). Sortie departed March AFB with a planned recovering at Carswell AFB, TX.[256]
  • On 16 December 1982, B-52G, AF Serial No. 57-6482, assigned to 328th BS, 93rd BW, Castle AFB, CA, was participating in a Minimum Interval Take-Off (MITO; 12 seconds between each aircraft on takeoff) from Mather AFB, CA. The incident aircraft was in the number two position of a three ship cell. The B-52G was equipped with water injection to give additional thrust on take-off. The lead aircraft was "dry" and did not utilize thrust agumentation[clarification needed]. The incident aircraft was "wet" and did use the thrust augmentation system. During the take-off, the incident aircraft rapidly started to overtake the lead aircraft. The incident aircraft pilot retarded the throttles rapidly causing flameout of four engines. The aircraft then stalled leading to impact with the ground. Nine crew members were killed. There were no fatalities on the ground.[257]
B-52H 61-0026 Czar 52 seconds before crashing during practice for an airshow on 24 June 1994. The copilot's escape hatch, detached during the incomplete ejection sequence, can be seen near the tip of the vertical stabilizer.
  • On 16 October 1984, B-52G, AF Serial No. 57-6479, assigned to the 92d Bomb Wing, Fairchild AFB, WA, clipped its wing on Hunts Mesa, an outcropping in Monument Valley, Arizona, and crashed, sending a fireball high into the air. Two of the seven crew perished in the crash, including Col. William Ivy, the wing's deputy commander for operations.[258][259]
  • On 2 February 1991, B-52G Hulk 46, assigned to the 4300th Bomb Wing (Provisional), Diego Garcia, British Indian Ocean Territory (BIOT) crashed while returning from a bombing mission in Iraq during the Persian Gulf War. The crash was eventually blamed on a catastrophic failure of the aircraft's electrical system. Three of the six crew members on board were killed.[260][261]
  • On 24 June 1994, B-52H Czar 52, AF Serial No. 61-0026 crashed at Fairchild Air Force Base, Washington, during practice for an airshow. All four crew members died in the accident.[262]
  • On 21 July 2008, a B-52H, Raidr 21, AF Serial No. 60-0053, deployed from Barksdale Air Force Base, Louisiana to Andersen Air Force Base, Guam crashed approximately Script error: No such module "convert". off the coast of Guam. All six crew members were killed (five standard crew members and a flight surgeon).[263]


There are many B-52s still in use and others on static display at USAF bases and museums around the world.

Notable appearances in media

The B-52 has been featured in a number of major films, most notably: Bombers B-52 (1957),[268] A Gathering of Eagles (1963),[269] Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964),[270] and By Dawn's Early Light (1990).[271] It has also been featured in numerous novels, such as most of the early Patrick McLanahan novels by Dale Brown, which feature one or more heavily modified B-52 bombers, nicknamed the "EB-52 Megafortress".[272] A 1960s hairstyle, the beehive, is also called a B-52 for its resemblance to the aircraft's distinct nose.[273] The popular band The B-52's was subsequently named after this hairstyle.[273]
