De OPThe Boeing IDS (formerly Rockwell) B-1B Lancer is a long-range strategic bomber in service with the USAF. Together with the B-52 Stratofortress, it is the backbone of the United States's long-range bomber force.
The B-1 was conceived as the Advanced Manned Strategic Aircraft (AMSA) program circa 1965. After a prolonged development period, the contract was awarded in 1970 to Rockwell International. The first of four prototype B-1A models flew on December 23 1974. Intended as a high-speed, long-range bomber capable of a supersonic low-level dash and Mach 2.5 at altitude, the B-1A never went into production. The program was canceled in 1977, although flight test of the four B-1A models continued through 1981. One of these aircraft now resides at the United States Air Force Museum in Dayton, Ohio and another at Wings Over the Rockies, in Denver, Colorado.
The Reagan administration restarted the B-1 program in 1981, originally as an interim bomber in anticipation of the stealthy Advanced Technology Bomber (which emerged as the B-2 Spirit). The first production model of the revised B-1B first flew in October 1984, and the first B-1B was delivered to Dyess Air Force Base, Texas, in June 1985, with initial operational capability on October 1, 1986. The final B-1B was delivered May 2, 1988.
A total of 100 front-line aircraft were produced at a cost of over $200 million each. After several write-offs, 93 remained by the turn of the century. In 2003 the USAF decided to retire 33 of the B-1Bs to concentrate its budget on maintaining availability of the remaining aircraft, although in 2004 a new appropriations bill called for some of the retired aircraft to return to service. In 2004 the USAF returned seven of the mothballed bombers to service, giving a total force of 67 aircraft, with the rest cannibalized for spares. Five of the seven being brought back to service are going to Dyess AFB in Texas, one to Ellsworth AFB in South Dakota, and another to Edwards AFB in California.
The B-1B did not have a popular name during its early USAF service. By the time it was given the official popular name "Lancer" in 1990 it had already become known to its crews as the "Bone" (a corruption of "B one," also said to be inspired by its somewhat eerie shape).
The B-1B holds several world records for speed, payload and distance. The National Aeronautic Association recognized the B-1B for completing one of the 10 most memorable record flights for 1994.
Sometimes criticized as redundant, the B-1B was given new life as the new threats of the 21st-century surfaced, and fills a niche in the Air Force inventory. It's worth noting that the project finished on budget, and has higher survivability and speed as compared to the older B-52 which it was intended to replace. With the arrival of limited numbers of B-2s in the 1990s and the continuing use of the B-52s, its value has been questioned. However, the capability of a high speed strike with a large bomb payload for time-sensitive operations is useful, and no new strategic bomber is on the immediate horizon. Because of its higher wing loading and more complicated systems, however, it is likely that the elderly B-52 will remain in service longer than the B-1B.
Operationally, the B-1B was first used in combat in support of operations against Iraq during Operation Desert Fox in December 1998. B-1s have been subsequently used in Operation Allied Force (Kosovo) and most notably Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom.
