The Northrop Grumman B-2 Spirit is a low-observable, strategic, long-range, heavy bomber capable of penetrating sophisticated and dense air-defence shields.Operated exclusively by the US Air Force, the B-2 Spirit is a second generation stealth aircraft, following the F-117A Nighthawk.
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. 21 B-2s have been delivered to Whiteman Air Force Base in Missouri, the first in December 1993.
The B-2 Spirit is a plane like no other. Tracing its roots back to the days when Jack Northrop created his flying wings, the YB-35 and the jet powered YB-49, in the 1940’s. In fact, the B-2 Spirit has the exact same wingspan as the YB-49: 172.0 ft or 52 m. It was back then that the flying wing design demonstrated the low radar signature, however the YB-49 was canceled in favor of the more conventional B-36 produced by Convair.
The B-2’s stealth comes from a combination of reduced acoustic, infrared, visual and radar signatures, making it difficult for defences to detect, track and engage. Many aspects of the low-observability process remain classified; however, the B-2’s composite materials, special coatings and flying wing design contribute to its stealth abilities. The B-2 uses radar absorbent material and coatings, that have required climate-controlled hangars for maintenance.
An assessment published by the USAF showed that two B-2s armed with precision weaponry can do the job of 75 conventional aircraft, and i think that kinda says it all.
