Northrop Grumman B-2 Spirit stealth bomber
The B-2 was developed/built by a team consisting of Northrop Grumman, Boeing, and Vaught Aircraft Industries, the country of origin is the United States. Its first flight was in 1989, and it was introduced into service in 1997. 21 were made, 20 of which are still in service. In 2008, one bomber crashed just after takeoff. The crew ejected and escaped harm.
It’s manned by two crewmen. It can carry a payload of up to either 80 500 pound (~230 kilogram) GPS-guided bombs, or 16 2400 pound (~1100 kilogram) nuclear bombs. It has an unrefueled range of around 6000 nautical miles (~9600 kilometers), and can travel a total of 10000 nautical miles on a single refueling.
The Spirit is a multi-role heavy bomber, the most dominant role being that of a stealth bomber. It’s a stealth bomber in that it has ‘low observability’, due to such things as reduced infrared, electromagnetic, radar, and visual signatures. These signatures are what modern-day defense systems use to track and detect aircrafts, and it goes without saying that giving off less of said signatures makes it harder to be detected.
