  | The Northrop Grumman B-2 Spirit is a multi-role stealth heavy bomber, capable of deploying both conventional and nuclear weapons. It is operated exclusively by the United States Air Force. Its development was a milestone in the modernization program of the U.S. Department of Defense. The B-2's second-generation stealth technology is intended to aid the aircraft's penetration role in order to survive extremely dense anti-aircraft defenses otherwise considered impenetrable by combat aircraft.The B-2 started life as a black project known as the High Altitude Penetrating Bomber (HAPB), then became the Advanced Technology Bomber (ATB), and later became the B-2 Spirit. An estimated US$23 billion were secretly spent for research and development on the B-2 in the 1980s. An additional expense was caused by changing its role in 1985 from a high-altitude bomber to a low-altitude bomber, which required a major redesign.The first B-2 was publicly displayed on 22 November 1988, when it was rolled out of its hangar at Air Force Plant 42, Palmdale, California, where it was built. Its first public flight was on 17 July 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 original procurement of 135 aircraft was later reduced to 75 in the late 1980s. In his 1992 State of the Union Address, President George H.W. Bush announced total B-2 production would be limited to 20 aircraft (later increased to 21 by refurbishing a test aircraft).This reduction was largely a result of the disintegration of the Soviet Union, which effectively rendered void the Spirit's primary mission.
The cost of the B-2 program in 1994 dollars was reported at $727 million per plane, however the total cost of the program with development, spares, and facilities averaged over $2.1 billion per plane as of 1997 according to the B-2 program office.The first operational aircraft, christened Spirit of Missouri, was delivered on December 17, 1993. The B-2 fleet is based at Whiteman Air Force Base in Missouri. Depot maintenance for the B-2 is accomplished by United States Air Force contractor support and managed at the Oklahoma City Air Logistics Center, Tinker Air Force Base, Oklahoma.Originally designed to employ nuclear weapons, modern usage has shifted towards a flexible role with conventional and nuclear capability.
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 and Vought Aircraft Industries, are members of the aircraft contractor team. Another 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).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 crash on takeoff of a 509th Air Wing, Air Force B-2 Spirit bomber, February 23 operating at Andersen Air Force Base, Guam, was caused by water in the aircraft's sensors, according to an Air Combat report issued, Thursday. Specifically, moisture in three port transducer units "distorted data introduced by a B-2 Spirit's air data system" which led to flawed information entering the bomber's flight control computers. The aircraft was reacting to inaccurate airspeed and a "perceived" negative angle of attack. This resulted in an "uncommanded 30 degree nose-high pitch-up on takeoff," according to the Air Force.
Major Ryan Link and Captain Justin Grieve, the aircraft's two pilots and the only two aboard were unable to regain control and safely ejected just as the aircraft stalled and mushed into the ground and its left wing impacted the ground. The $1.4 billion aircraft crashed just off the left side of the runway and exploded. It was the first-ever B-2 crash and followed 75,000 hours of loss-free service. Link and Grieve both suffered injuries during ejection, with Grieve suffering compression fractures to his spine.
The report points to the inaccurate readings as contributing factors, adding that ineffective communication of critical information about a technique used to remove moisture from the sensors also contributed. It's possible that all the maintenance crew had to do to avert the accident was turn on the pitot heat prior to performing air data calibrations. But the suggested technique was not part of checklist procedures.

 | Northrop Grumman B-2 Spirit is a multi-role stealth heavy bomber. The B-2's composite materials, special coatings and flying-wing design all contribute to its "stealthiness." One of the most expensive planes ever built: estimates for the costs per plane range from 1.1 to 2.2 billion USD. Music: Massive Attack - 'Future Proof'.
