The B-2 Spirit is a two-person crew-only aircraft that can carry both conventional and thermonuclear missiles. The first flight of this Northrop Grumman Corp. jet occurred in 1989, and it was manufactured up to 2000. Stealth Bombers from the 1990s are still in service today, despite the project’s short lifespan due to exorbitant costs. There were 21 made.
