The year was 1999. In the former Yugoslavia, the Kosovo War was underway, and NATO had joined the conflict as part of Operation Allied Force. During the campaign, NATO fighter jets launched a massive wave of airstrikes against Serbia.<\/p>\n

On the night of March 27, 1999, a U.S. Air Force F-117 stealth fighter was en route to bomb targets in Serbia. Until that evening, it was considered virtually undetectable by radar. Then it was spotted\u2014and shot down.<\/p>\n

Not Invisible<\/strong>
\nThe aircraft was brought down by a Soviet-made surface-to-air missile dating back to the Cold War. The missile battery crew spotted the jet when its bomb bay doors were open, creating a larger radar signature. They fired two missiles\u2014one struck the target and took it down.<\/p>\n

Not Quite Hollywood<\/strong>
\nThe term \u201cstealth fighter\u201d immediately conjures up scenes from Hollywood: a jet gliding past air defenses without leaving a trace. But as always, reality is more complex. A stealth aircraft isn\u2019t invisible\u2014it\u2019s just harder to detect. Nor is it immune to missiles\u2014it\u2019s simply harder to lock onto.<\/p>\n

So What Is Stealth?<\/strong>
\nFirst, let\u2019s understand how aircraft are detected. There are three main methods: radar, heat signature, and visual identification.<\/p>\n

Radar<\/strong> \u2013 The most common detection method, radar works by emitting radio waves and analyzing the echoes that bounce off airborne objects. The larger and more reflective an object is, the more clearly it appears on radar.
\nHeat Signature<\/strong> \u2013 All objects emit heat, especially jet engines. Thermal sensors can detect this heat and guide missiles toward it.
\nVisual Detection<\/strong> \u2013 A low-flying jet may be spotted with the naked eye, especially when noise or motion gives it away. Sometimes, simply seeing the aircraft is enough to indicate an imminent attack.<\/p>\n

How Does a Stealth Fighter Counter These Methods?<\/strong>
\nThe body of a stealth aircraft is designed with sharp angles to deflect radar waves away from the source, instead of bouncing them directly back. In addition, radar-absorbent materials further reduce reflections. The result: a much smaller radar signature.<\/p>\n

To minimize heat detection, stealth aircraft employ several techniques: injecting cool air into the exhaust to lower the jet temperature, enlarging the exhaust nozzles to spread heat over a broader area, and limiting the use of afterburners, which drastically increase thermal visibility.<\/p>\n

As for visual detection\u2014there\u2019s not much that can be done. Many countries camouflage their aircraft to blend with the terrain, which is one reason for the Israeli Air Force\u2019s distinctive paint schemes. Stealth aircraft, however, are coated with a special paint that absorbs radar waves.<\/p>\n
