How does the B2 Spirit achieve its stealth capabilities?

The B2 Spirit achieves its stealth capabilities through multiple advanced techniques. Its unique flying wing shape with smooth panels and minimal seams creates an exceptionally low radar cross section, providing aerodynamic efficiency while minimizing radar reflection. The aircraft's exterior is coated with classified radar-absorbent materials that absorb radar energy rather than reflecting it back to detection systems. Additionally, the B2 conceals its engines by burying them deep within the aircraft's body with intakes hidden on top of the wing, preventing radar waves from bouncing off engine fan blades. Its exhaust is cooled and spread across a wide area to reduce infrared signature. These innovations, combined with sophisticated electronic countermeasures, result in a bomber with a radar cross section approximately 1,000 times smaller than a conventional B-52, making it virtually invisible to enemy detection systems.
