Passage: The development of stealth aircraft, exemplified by the F-117 Nighthawk, marked a paradigm shift in military aviation. Contrary to the common misconception that stealth technology makes an aircraft completely invisible to radar, its actual purpose is to drastically reduce the radar cross-section (RCS), which is the detectable size of the aircraft. The F-117 achieved this not through radar-absorbent materials alone, but primarily through a revolutionary design philosophy. Its airframe was constructed with a multitude of flat panels, or facets, angled to deflect incoming radar waves away from the radar receiver, rather than scattering them back. This design, while aerodynamically challenging, was a masterstroke of radar evasion. The operational success of the F-117, first seen in combat during Operation Just Cause in Panama in 1989, validated the concept and paved the way for future generations of low-observable aircraft. According to the passage, what was the primary method the F-117 Nighthawk used to reduce its radar visibility?
