The B-2 Spirit is a stealth bomber developed by Northrop Grumman for the United States Air Force. It is 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 signature. With a wingspan of 172 feet, the B-2 can carry up to 40,000 pounds of payload. It is powered by four Pratt & Whitney F118 engines, allowing it to fly at high altitudes and long ranges. The B-2 has been in service since 1997 and plays a crucial role in the U.S. military's strategic capabilities.
