The Stealth B-2 Spirit Multi-Role bomber is a versatile capable of delivering conventional and nuclear munitions. Along with the B-52 and B-1B, B-2 provides the flexibility and effectiveness inherent in manned bombers penetration. Its low-observable or "stealth" characteristics give it a unique ability to penetrate sophisticated defenses of an enemy and endanger their most cherished goals, and strongly defended. His ability to penetrate air defenses and threaten effective retaliation was expected to give an effective deterrent and combat force well into the 21st century.
The mixture of low-observable technologies for high aerodynamic efficiency and large payload gave the B-2 bombers benefits most important ones. Its low-observability provides freedom of action at high altitude, increasing its scope and a better view to the aircraft's sensors.
