The X-4





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.
