Development History and Design Features
The development of the B-2 Spirit began in the 1980s, as the United States sought to create a stealth bomber that could penetrate heavily defended airspace and deliver precision-guided munitions. The project was shrouded in secrecy, with the US Air Force and Northrop Grumman working closely together to develop the aircraft’s advanced stealth technology and flying wing design. The B-2’s unique shape and radar-absorbent materials reduce its radar cross-section, making it difficult to detect and engage. The aircraft’s four non-afterburning General Electric F118-GE-100 engines provide a high thrust-to-weight ratio, allowing the B-2 to achieve a top speed of over Mach 0.95.
Stealth Technology and Radar-Absorbent Materials
The B-2’s stealth technology is based on the use of radar-absorbent materials (RAMs) and a unique design shape that reduces the aircraft’s radar cross-section. The RAMs are applied to the aircraft’s surface, absorbing or scattering radar waves and reducing the amount of energy reflected back to the radar antenna. The B-2’s flying wing design also helps to reduce its radar cross-section, as there are no vertical stabilizers or other protrusions to reflect radar waves. The combination of RAMs and the flying wing design makes the B-2 extremely difficult to detect, even for advanced radar systems.
