B-2 Spirit

The Northrop Grumman B-2 Spirit (also known as the Stealth Bomber) is an American heavy bomber with "low observable" stealth technology designed to penetrate dense anti-aircraft defenses and deploy both conventional and nuclear weapons. Because of its considerable capital and operations costs, the project was controversial in Congress and among Pentagon brass. During the late 1980s and early 1990s, Congress slashed initial plans to purchase 132 bombers to just 21. The cost of each aircraft averaged US$737 million in 1997 dollars. Total procurement costs averaged US$929 million per aircraft, which includes spare parts, equipment, retrofitting, and software support. The total program cost, which includes development, engineering and testing, averaged US$2.1 billion per aircraft (in 1997 dollars). Twenty B-2s are operated by the United States Air Force. Though originally designed in the 1980s for Cold War operations scenarios, B-2s have been used in combat to drop bombs on Serbia during the Kosovo - Serbia Conflict in the late 1990s, and see continued use during the ongoing wars in Iraq and Afghanistan. One aircraft was lost when it crashed on takeoff in 2008.

Northrop Grumman B-2 Spirit (cunoscut si sub numele de Stealth Bomber) este un bombardier american greu, cu tehnologie stealth „observabila”, conceput pentru a patrunde in apararile dense antiaeriene si a desfasura atat arme conventionale, cat si nucleare. Datorita costurilor sale considerabile de capital si operatiuni, proiectul a fost controversat in Congres si in cadrul Pentagonului.
