History

The B-2 started life as a black program" known as the High Altitude Penetrating Bomber (HAPB), it then became the Advanced Technology Bomber (ATB) and used the project code word Senior Cejay, it later became the B-2 Spirit. An estimated 23 billion dollars was secretly spent for research and development on the B-2 in the 1980s. An additional cost driver was that the mission was changed in 1985 from a high altitude bomber to a low altitude penetrating bomber, which required a major redesign. Because the development of the B-2 was one of the best kept secrets of all USAF programs, there was no opportunity for public criticism of its massive cost during the development process. The first B-2 was publicly displayed on November 22, 1988, when it was rolled out of its hangar at Air Force Plant 42, Palmdale, California, where it was manufactured. Its first flight was on July 17, 1989. The B-2 Combined Test Force, Air Force Flight Test Center, Edwards Air Force Base, California, is responsible for flight testing the engineering, manufacturing and development aircraft.

The first aircraft, named Spirit of Missouri, was delivered on December 17, 1993. Depot maintenance responsibility for the B-2 is held by Air Force contractor support and is managed at the Oklahoma City Air Logistics Center at Tinker Air Force Base in Oklahoma.

The prime contractor, responsible for overall system design and integration, is Northrop Grumman Integrated Systems Sector. Boeing Integrated Defense Systems, Hughes Aircraft (now Raytheon), General Electric Aircraft Engines Group and Vought Aircraft Industries, are key members of the aircraft contractor team. Another major contractor, responsible for aircrew training devices (weapon system trainer and mission trainer) is Link Simulation & Training, a division of L-3 Communications formerly Hughes Training Inc. (HTI). [5] Link Division, formerly known as CAE - Link Flight Simulation Corp. Link Simulation & Training is responsible for developing and integrating all aircrew and maintenance training programs. The military contractors for the B-2 engaged in massive lobbying campaigns to gain Congressional support for its funding.

Whiteman Air Force Base in Missouri was the B-2's only operational base until early 2003, when facilities for the B-2 were constructed on the joint U.S./U.K. military base on the British island of Diego Garcia in the Indian Ocean, followed by deployment to Guam in 2005. Facilities for the aircraft have also been constructed at RAF Fairford in Gloucestershire in the United Kingdom.
