The Northrop Grumman B-2 Spirit is a stealth bomber used by the United States Air Force. It was designed to penetrate dense anti-aircraft defenses and deliver both conventional and nuclear munitions. The aircraft features a unique flying wing design, which helps reduce its radar cross-section, making it less detectable by enemy radar systems. First introduced in the late 1980s, the B-2 Spirit has a range of over 6,000 miles without refueling. It can carry a variety of weapons, including precision-guided bombs and nuclear weapons. The B-2 remains a critical component of the U.S. military's strategic bombing capabilities.
