The B-1B Lancer is a very impressive long-range intercontinental strategic bomber, developed by U.S. company Boeing for U.S. Air Force. The B-1B is in service since 1986. U.S. Air Force has 67 of these bombers with two of the tests. The crew consists of a pilot who is also commander of the aircraft, a passenger and two weapon system officers. The B-1B Lancer bombers are stationed at Dyess Air Force Base and Ellsworth Air Force Base.
The project for the development of the B-1A to replace the B-52 Stratofortress began in 1970. Four prototypes have been made which could reach a supersonic speed of Mach 2.2. The project was halted in 1977, but test flights continued until 1981.
In 1981 he began again with the development of B-1 of the project. The B-1, who was appointed today as the B-1B has big changes in the burden of a larger weapon than 74,000 pounds, an improved radar and a radar cross-section than an order of magnitude. The air intake ducts have also been modified, but left the maximum speed to about Mach 1.2.
The first B-1B flew in October 1984 and was delivered to the U.S. Air Force Dyess Air Force Base in June 1985. The last was delivered on May 2, 1988. On October 1, 1986, the first B-1B Lancer became operational.
