Legend: This Is Plane That Started the Stealth Revolution
Meet the F-117.
by Sebastien Roblin
The Nighthawk’s radar cross section is generally given as .001 cubic meters—excellent compared to the 5 to 10 cubic meters of a conventional jet fighter. Nonetheless, the Raptor’s cross section is believed to be ten time better, at .0001 meters squared. Given the continual improvements made to both low-and high-bandwidth radars in order to counter stealth fighters, minimizing the cross section is vital.
The F-117 Nighthawk , America’s original stealth plane with a deeply sinister appearance, is an example of a weapon system designed around the limitations imposed by a promising new technology. The Nighthawk was revolutionary when it entered service in 1983—not that many could appreciate that, as the plane was kept secret from the public for five years.
