    The Lockheed F-117A was an innovative design that was able to penetrate the radar systems of its day through a combination of reflective surfaces that were angled and covered in an absorbent material that reflected little return to the radar receiver. In 1991 F-117A aircraft flew over Baghdad in the opening night of the Gulf War with immunity, dropping guided munitions that disrupted the Iraqi command and control centers, without loss. Today’s technology has improved the stealthiness of fighter and bomber aircraft and cruise missiles to the point that the F-117A has become obsolete. I hate to see this pioneer go, but they will live on in museums.

    • During the first Gulf war, they discovered it could be detected by…..cell phone towers. It affected cell signals when flying near towers, allowing triangulation. Not as accurate as radar, but if the signal disruptions were detected, it was a kind of early warning system.

      There has been an electronic arms race since WW2. The Luftwaffe bombed a Chain Home tower, but the Brits anticipated that and had a replacement up in a matter of hours. At the time, the Germans had little understanding about what it was, so did not understand the importance.

      • Terry Welshans says:

        A little touch of ‘irony’ from Japan. The Japanese had relatively poor radar and it was not found on large ships until very late in the war. They did have radar at their larger airports. The ‘irony’ is that the airport radar was disrupted by the steel structure of a nearby bridge. They developed a paint containing small particles of iron that scattered the radar waves while absorbing some of it. It worked! After the war, the US and British technology teams that exploited the Japanese military discovered the special ‘iron ball’ paint. That paint, modernized and perfected, was applied to the U-2, A-12, SR-71, and the F-117. A more refined version was used on the B-2 and most current 5th generation stealth fighters.

        • Speaking of which, I like these photos, and especially the first comment.

          • Terry Welshans says:

            Contrails are a giveaway. Stealth is not invisibility, just a reduction in detectability. It works only for a specific spectrum and aspect. You have to do the best you can against the most probable threat. There are visible, thermal, audible, and radio reflective considerations. Modern radars are adaptive on-the-fly with frequency hopping that detects in a number of wavelengths. Another technique, similar to the method you noted, is bi-static radar where the transmitter and receiver are quite a ways apart to ‘catch’ the reflected energy.
