On November 22, 1988, B-2A is a stealth high-speed gun from the 1978 program. The first prototype of 6 made its flight flight on July 17, 1989 with an extermination test in 1997. -2 is equipped with a 'pedal wing', with the edges along with the surrounding edges to help distort the radar. Exhausts in the upper and upper part of the unit are helping to reduce infrared signals. The USAF plans to get a plurality of 20 B-2A airports.
B-2 will probably be created only with smaller numbers (currently 21 are ordered), because the cost of installing all the B-52 elements is considered to be too high. B-2 is a stealth bomb, a design of high-speed, wooden plane, but angular wing and double-W sequences. These four engines are deeply buried in the reduction phase. B-2 is difficult and cost effective, and 124 hours of repair by hour driving.
ATB development (Advanced Technology Bomber) began in 1978; The program was publicized in 1981, when Norroprop design was selected on Lockheed / Rockwell's advice. Although the design of the designs was not visible, it was widely thought that the plane would be "an airplane", based on the experiences of Norththrop and XB-35 and YB-49, and this was confirmed when the first exhibition was released on November 22, 1988. Make its first flight on 17 July 1989, and the first production B-2 was awarded to the USAF in 1993. Production plans have been severely reduced from 135 to 20 flights, which will be expected to be released in 1997. This aircraft was called "Spirit" in February 1994; Northrop was Norththrop Grumman in May 1994.
Vital figures (B-2A): length of 21.03 m, range of 52.42 m, empty weight 72575 kg, empty weight 168434 kg, maximum speed 1103 km / h, 13898 km, uploaded 22370 Kg; Power plant: four 84.51 kN General Electric F118-100 in Turbofans.
On February 23, 2008 a B-2 bomb crash in the Guam area after leaving, but both drivers were safely driven.

Mission
The spirit of B-2 is a multinational force capable of bringing both natural and nuclear weapons. A major technological emergence, the bomb represents the most important step in the current U.S. system. B-2 brings great power to catch fire, in a short time, anywhere in the world through the impossible protection.
Features
With B-52 and B-1B, B-2 provides flexible and efficient variables from human bombs. Its seemingly low, or "bad" symptoms, provide unique ability to enter the enemy's defense and threaten its most valuable, most secure purposes. Its ability to enter into air protection and threaten effective retaliation has given strong, effective and effective forces to fight during the 21st century.
The compact appearance of a small visual technology with excellent energy efficiency and high-paying payout offers the most important B-2 benefits over existing guns. Its lack of foresight gives great freedom of action to the highest places, thus increasing its range and better aircraft aircraft. Its total range can be 6,000 square miles [9,000 km] nautical (9,600 km). The lowest view of B-2 depends on the integration of infrared, acoustic, electromagnetic, visual and radar. These designs make it difficult for these complex systems to find, trace and engage in B-2. Many features of the lowest process of keeping them are always separated; However, B-2 construction materials, special dressing and the design of all swimsuit wings play a part in "behavior."
B-2 has a team of two operators, the airline on the left side and the military commander on the right, compared to the B-1B staff with five B-52 employees. Thend Joint Air-to-Surface Standoff Missile. B-2s, in a conventional role, staging from Whiteman AFB, MO; Diego Garcia; and Guam can cover the entire world with just one refueling. Six B-2s could execute an operation similar to the 1986 Libya raid but launch from the continental U.S. rather than Europe with a much smaller, more lethal, and more survivable force. Background The B-2 development program was initiated in 1981, and the Air Force was granted approval in 1987 to begin procurement of 132 operational B-2 aircraft, principally for strategic bombing missions. With the demise of the Soviet Union, the emphasis of B-2 development was changed to conventional operations and the number was reduced to 20 operational aircraft, plus 1 test aircraft that was not planned to be upgraded to an operational configuration. Production of these aircraft has been concurrent with development and testing. The first B-2 was publicly displayed on Nov. 22, 1988, when it was rolled out of its hangar at Air Force Plant 42, Palmdale, Calif. Its first flight was July 17, 1989. The B-2 Combined Test Force, Air Force Flight Test Center, Edwards AFB, Calif., is responsible for flight testing the Engineering, Manufacturing, and Development aircraft as they are produced. Five of the six developmental aircraft delivered to Edwards are still involved in continuing flight testing. The first test aircraft is currently kept in flyable storage. Whiteman AFB, Mo., is the B-2's only operational base. The first aircraft, Spirit of Missouri, was delivered Dec. 17, 1993. Primary maintenance responsibility for the B-2 is divided between Oklahoma City Air Logistics Center at Tinker AFB, Okla. for avionics software (contractor); Ogden Air Logistics Center, Hill AFB, Utah for landing gear and trainers (contractor); and the Northrop-Grumman facility at Air Force Plant 42 at Palmdale for periodic depot maintenance. The prime contractor, responsible for overall system design and integration, is Northrop Grumman's B-2 Division. Boeing Military Airplanes Co., Vought Aircraft Co., Hughes Radar Systems Group and General Electric Aircraft Engine Group are key members of the aircraft contractor team. Another major contractor, responsible for aircrew training devices (weapon system trainer and mission trainer) is Hughes Training Inc. (HTI) - Link Division, formerly known as C.A.E. - Link Flight Simulation Corp. Northrop-Grumman and its major subcontractor HTI, excluding Link Division, is responsible for developing and integrating all aircrew and maintenance training programs.
