Difference between Lockheed F-117 Nighthawk and Radar cross-section

Lockheed F-117 Nighthawk vs. Radar cross-section

The Lockheed F-117 Nighthawk is an American single-seat, twin-engine stealth attack aircraft that was developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). Radar cross-section (RCS) is a measure of how detectable an object is by radar.
