B-2 Spirit bombers are extremely stealthy heavy bombers, which have intercontinental range with air refueling. They are certified to carry nuclear weapons, and also large numbers of conventional bombs, usually precision-guided munitions.

The B-2 is the second generation of operational stealth aircraft. Its surfaces are much more curved than those of the F-117 Nighthawk, as at the time the F-117 was designed, not enough computer power was available to model the complex interactions of radar with curved surfaces.

The United States operates one wing of B-2 aircraft from Whiteman Air Force Base, Missouri, which is subordinate to the Eighth Air Force. They are occasionally forward-deployed to Guam or Diego Garcia.
