The B-2 Spirit is a strategic, long-range stealth bomber. It boasts a flying wing design, uses radar-absorbent materials, and has a low infrared signature, resulting in a very small radar cross-section, making it difficult to detect by conventional radar systems. Key specifications include a wingspan of 172 feet, a length of 69 feet, and a height of 17 feet. It is powered by four General Electric F118-GE-100 turbofan engines, has a crew of two, and a maximum takeoff weight of 336,500 pounds.
