Northrop Grumman B-2 Spirit stealth fighter technology is used for the bomber (Stealth Bomber). The plane is made of thermoplastic material that is used by the U.S. Air Force War. "Northrop Grumman is the prime contractor for the U.S. Air Force stealth bomber B-2 Spirit."
This aircraft was first introduced to the public, and first flew in 1988, July 17, 1989, as still active. The aircraft is not able to fly quickly and easily destroyed if visible. Therefore, Northrop Grumman has developed a new radar absorbent coating to preserve the characteristics of the B-2's stealth drastically, to reduce maintenance time. The new material, known as an alternate high frequency material (AHFM), applied by four robots are controlled independently.
The mission of this aircraft is to destroy the enemy base or military bases, without visible radar. Excess B-2 is able to penetrate the air defense shield (radar) is advanced. The aircraft is capable of attacking all targets from an altitude of up to 50,000 feet (16.656 kilometers) from the sea level, with a range of more than 6,000 nm without refueling (unrefueled) and over 10,000 nm with one refueling, giving the ability to fly to any point in the world within a few hours.
situation in the plane.Twenty-one pieces of the B-2 Spirit was first delivered to Whiteman Air Force Base in Missouri, in December 1993. In the first three years of service, the operational B-2 Spirit, reached a level of reliability of 90%, when a surprise attack. An assessment published by the USAF showed that two B-2 Spirit with precision weaponry can do the job of 75 conventional aircraft.
For a mission abroad, has also developed a system that can be transported to a hangar various destinations, in various countries. A hangar system, has a length of 126 feet, 55 feet wide and 250 feet tall. The first hangar hangar has been established at Diego Garcia in the Indian Ocean.
refueling in the air.Before the development of this hangar system, each performing a mission akli depleted, B-2 Spirit must return to Whiteman AFB, for the maintenance of the "stealth" of the aircraft. B-2 Spirit is used for the first time during Operation Iraqi Freedom in March / April 2003. In March 2005, the squadron of B-2 was placed for the first time to Andersen Air Force Base in Guam, with aircraft B-1 and B-52, to support and strengthen the defense of the USAF Command Asia Pacific. Others focused on the war in the Middle East.
Demons were often seen in the area of Kosovo, Iraq, and Afghanistan. Making a triangular futuristic aircraft that spent USD 737 million - 2.2 billion per unit. These costs make the stealth bomber became the most expensive military aircraft in the world.
B-2 Spirit is a carrier aircraft bombs (bomber) with stealth technology (stealth) is a mainstay of the U.S. Air Force for long-range operations. Aircraft including the B-2 Spirit strategic bomber as one that has been recognized by the military ability. Unique capacities , including its stealth characteristics, allow the bombers to penetrate enemy defenses once the most stringent, and with high precision can drop bombs on targets belonging to the opponent vital. Permissibility B-2 Spirit has been shown in military operations in Iraq a few years ago.
Strategic bomber B-2 Spirit is only owned and operated by the U.S.. This stealth aircraft is a blend of cruising the farthest, the largest carrying capacity weapons, and stealth technology that is unmatched by any air force. Without refueling, the B-2 Spirit is able to take flight as far as 6,000 nautical miles, and with one refill of fuel in the air, the plane can travel a distance of 10,000 nautical miles. With a payload capacity of 20 tons of conventional and nuclear weapons, and send it in the right weather conditions, the B-2 has the ability to change the outcome of a conflict only with a bombing mission.
Bomber B-2 Spirit has been developed since 1978 under the program ATB (Advanced Technology Bomber). The new ATB program became public in 1981. And on November 22, 1988, a new public also knows about the existence of manufactured strategic bomber Northrop Grumman is then made its maiden flight on July 17, 1989.
As a strategic bomber that is difficult to beat, B-2 Spirit certainly has a very high price, even becoming a military aircraft with the most expensive price ever in the history of military aviation. Informed that the price of one unit of B-2 Spirit is a U.S. $ .2,4 billion. Operational and maintenance costs no less expensive. For one hour flight, the aircraft needed treatment for 124 hours.
The U.S. military initially planned to purchase 132 units of the B-2 Spirit bomber. But collided with a very expensive price, only 21 units were realized purchase. After the accident 1 unit B-2 Spirit at Andersen Air Base in Guam, the number of B-2 that strengthens the U.S. Air Force to 20 units. Currently 19 unit B-2 Spirit is based in Whiteman air base. Meanwhile, one unit of B-2 Spirit is in the air base Edward, Calif., for software development and armament systems.
History Grey.As with other aircraft, despite having all the advanced equipment, B-2 Spirit Stealth Bomber never experienced a period of gray. Super sophisticated B-2 bomber, crashed after a failed takeoff from Andersen Air Base in Guam, Pacific Islands, Saturday (23/02/2008) at around 10:45 local time. This is the first anti-aircraft radar incident dubbed "Demon" who fall since its introduction to the public in 1988.
Capt. Sheila Johnston, a spokesman for Air Combat Command at Langley Air Force Base Center of Virginia, USA, said, in an incident that two pilots reportedly managed to get out of the plane, who was not carrying ammunition, and survived.
Both crew members were withheld his name from combat units 509. "We are investigating the cause of the accident immediately," said Johnston.
According to Maj. Eric Hilliard of Hickham airbase, Hawaii, the B-2 weighs 152.6 tons that crashed shortly after take-off with three similar aircraft. The accident occurred when one of the three aircraft capable of driving 716 miles per hour it suddenly slid down. This is their flight schedule last four months after operation. As a result of this accident, three other aircraft directly secured in Guam. "Before the B-2 stealth aircraft crashed, actually there is one other stealth aircraft successfully took off. However, the aircraft's call to the base some time after the incident," he explained. But this plane resumed operations in April 2008.
Pentagon spokesman Geoff Morrell confirmed the incident immediately to the Secretary of Defense at the time, Robert Gates. But, Gates was on a visit to some Pacific countries, including Indonesia, declined to give further details.
