The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions anywhere on the globe. Its "stealth" characteristics blend low-observable technologies with high aerodynamic efficiency and large payload, providing greater freedom of action at high altitudes. This increases its unrefueled range to approximately 6,000 nautical miles.
