The X-4 is considered by most to be the worlds first practical air to air guided missile. It was developed in 1942-43 at the "Ruhrstahl" firm in Brackwede by Dr. Max Kramer.The missile was to be wire guided to the vicinity of enemy bomber formations, at which point (15 meters) the missile's acoustic proximity fuze would detonate the 20kg. HE warhead.
It is believed that during the last weeks of the war in Europe, several launches, included in the test program, were made against enemy bombers. I have found no documentation to verify this. The X-4 was never delivered to the Luftwaffe. However, had the war with Germany lasted a few more months, the scene pictured above might have been.
