military-aircraft-b-1b

In 1969 the US Air force issued a requirement for a strategic bomber to replace the B-52. On December 23 1974 the prototype of the swing wing B-1A first flew, and this was also the first flight for the new General Electric F-101 reheated turbofan. Three other prototypes soon joined the program, but the B-1A was canceled in June 1977. In October 1981 the B-1 program was revived. But whereas the original B-1A had been a Mach 2.2+ medium high altitude bomber, the new B-1B was to be a far "stealthier" low altitude type with only limited supersonic capability. The airframe was beefed up for higher weights and the rigors of low altitude flight at high supersonic speed, the engine nacelles were simplified, and "stealth capability" was added by the used of radar absorbent materials, an advanced electronic suite, and modification of the nacelles to prevent radar energy reaching the face of the engine compressors. The B-1B flew in September 1984, and 100 aircraft were delivered between July 1985 and April 1988.
