Lockheed Martin FB-22

The Lockheed Martin FB-22 (sometimes called the Strike Raptor) was a proposed United States Air Force bomber aircraft. Its design was derived from the F-22 Raptor. The FB-22 was canceled following the 2006 Quadrennial Defense Review.
Design and development
In 2002, Lockheed Martin began studying a medium bomber version of the F-22 Raptor fighter, featuring a delta wing, longer body and greater range and payload. The FB-22 design was based on existing and planned capabilities of the F-22 fighter; such a heritage would have reduced costs and risks of development compared to a new design. The FB-22 was planned to serve as a regional bomber, a role previously covered by the General Dynamics F-111 Aardvark.
The design of the FB-22 differs significantly from the F-22. A lengthened fuselage and larger delta wing provide greater fuel capacity for greater range of some Script error: No such module "convert".. The FB-22's fuselage also allows for a larger internal weapons bay. The design could also have been adapted to use a more powerful engine, such as the F-35 Lightning II's Pratt & Whitney F135, or the General Electric/Rolls-Royce F136. The FB-22 was to have a maximum speed of Mach 1.92.
One early FB-22 concept featured no tailplanes. The FB-22 design incorporated twin tailplanes and likely would have fixed engine nozzles as opposed to the thrust vectoring nozzles on the F-22. The FB-22 design could carry 30 Small Diameter Bombs (SDB), which weigh just Script error: No such module "convert"., compared with the F-22's payload of eight.
Research has been conducted to develop a stealth ordnance pod and pylon. Such a pod would have had a low observable shape and have carried weapons internally, then would have opened when launching a missile or dropping a bomb. This allows a stealth aircraft to carry more ordnance than in the internal bays alone, while maintaining the craft's stealth characteristics. The pod and pylon design allows it to be detached when no longer needed.
The FB-22 was put forward as a candidate for the USAF's requirement for an interim bomber with strategic capabilities to become operational by 2018, which is to serve as a stop-gap until the entry into service of a future bomber planned for 2037. In order to achieve such an ambitious entry into service date, an aircraft based on an already proven platform (such as the FB-22) may have been desired. Because of the work already done on the F-22, the cost of developing the FB-22 was estimated to be as low as 25% of developing a new bomber, with the development of the airframe expected to cost US$1 billion (2003 dollars). In 2003, Air Force Secretary James Roche envisioned that there would be 150 FB-22s inducted into the service. However, the FB-22 in its planned form appears to have been canceled in the wake of the 2006 Quadrennial Defense Review and subsequent developments as the DoD favored a bomber with much greater range. The USAF has favored a subsonic stealth bomber similar to the existing B-2.
