The B-2 Spirit is one of three strategic heavy bombers in U. Originally conceived to infiltrate the Soviet air-defense network and attack targets with nuclear weapons, over the decades its mission has grown to include conventional precision attack.
The B-2 is the most advanced bomber in U. In the late s, the administration of President Jimmy Carter opposed the high-speed B-1A bomber as a waste of government money.
Carter had been briefed on the new field of stealth technology and was responsible for the development of the FA stealth fighter. Little was known about the bomber at the time except that it would incorporate new radar-evading technologies and possibly a dramatically different shape than previous bombers.
Northrop was a curious pick—after all, it had not produced any bombers since World War II.
Northrop had been working on stealth since at least the mids. At a research facility in Rancho Palos Verdes, California Northrop had been working on radar-evading aircraft shapes and radar-resistant materials.
The company lost the competition to build the Experimental Survivable Test Bed XSTwhat would later become the stealth fighter to Lockheed, but did win the opportunity to build another stealth test bed, Tacit Blue. Tacit Blue featured degree stealth, a must-have for a penetrating strategic bomber.
Engineers had long known that flying wings had a minimal radar signature, and flying wings were a Northrop specialty. The company had produced four flying wings: None had been picked up by the Air Force, but it gave Northrop a great deal of experience with the aircraft form.
A flying wing properly shaped to further confound radar and use of advanced composite materials would create the ultimate penetration bomber, undetectable by radar.
The B-2 was developed as a black program, with all of the pluses and minuses that entails. On the plus side, it was developed with a high level of secrecy, and until rollout in few were sure exactly what the B-2 looked like.
On the other hand costs—and development problems that caused them to rise—were kept secret until The cost of the overall B-2 program rose from Approximately one billion was spent strengthening the wing, an Air Force requirement, should the bomber связан заболеванием рака заключению специалистов женщины могут потреблять пиво 0 be required to fly at low altitude.
There were also allegations of fraud and overcharging, at least one of which was settled out of court. The poisoned relationship between the Air Force and Northrop is regarded by some as one reason why the Advanced Technology Fighter competition, which produced the FA Raptor fighter, went to competitor Lockheed Martin and not Northrop. Like previous Northrop designs it lacked a tail, seamlessly blended wing and body, and buried its four General Electric FGE non-afterburning turbofans deep within the aircraft fuselage.
The value of stealth had not been proven in battle, and Congress began to fret about the cost of the projected aircraft.
The number of aircraft was eventually trimmed to just twenty-one. The B-2 is sixty-nine feet long and seventeen feet high.
It has wingspan of feet—exactly the same as that of the XB and YB It has a speed of miles an hour, and had a maximum altitude of 50,00 feet. It has an unrefueled range of 6, miles, and has midair refueling capability.
Связан заболеванием рака заключению специалистов женщины могут потреблять пиво 0 new bomber was one of the first military aircraft to make widespread use of new composite materials. Nearly 80 percent of the aircraft is made from woven composites that incorporated glass, carbon, and graphite fibers, while the remainder is made of aluminum and titanium.
The Spirit also has a radar absorbent coating whose sole purpose is to further reduce the radar signature. View the discussion thread. This is the unintended output of regime change, of toppling a tyrant and attempting to socially engineer a foreign society. Once the war begins, once society is destabilized, the chips fall where they may. The Trump team needs to regroup in order to develop, in close coordination with Japan and South Korea, a unified strategy that protects the interests of America and its allies.
