The Ruhrstahl X-4 was a wire guided air-to-air missile designed by Germany during World War II. The X-4 did not see operational service and thus was not proven in combat.
Work on the X-4 began in June 1943, by Dr Max Kramer at Ruhrstahl. The idea was to build a missile with enough range to allow it to be fired from outside the range of the bombers' guns , while being guided with enough accuracy to guarantee a "kill". The X-4 met these specifications and more; its BMW 109-448 rocket motor accelerated the missile to over 1,150 km/h and kept it there during its "cruise", between 1.5 and 4 km, while the defensive guns had a maximum effective range of about 1000 m.
The missile was stabilized by spinning it slowly in flight, at about 60 rpm. This meant any asymmetrical thrust from the engine, or inaccuracies in the control surfaces, would be evened out as the missile spun. Signals were sent to the missile over two wires wound onto spools on the missile body, and corrected the direction of flight by operating control surfaces on the tail. The warhead consisted of a 20 kg fragmentation device that had a lethal radius of about 8 m.
The first flight test occurred on August 11, 1944 using a Focke-Wulf Fw 190 to as the launch platform. Subsequent tests used the Junkers Ju 88 and Messerschmitt Me 262, although they were not launched from the latter. The X-4 had originally been intended for use by single-seat fighters, but the problems in guiding both the missile and the aircraft at the same time proved this to be unworkable. Instead the X-4 was re-directed to multi-seat aircraft like the Ju 88, while the R4M rocket was to be used on the single-seaters.

    No, because the only usable a-bombs USA used for Japan where made in Germany. They got captured only after Allied victory, so they weren't used against Germany but Japan.. Sadistic US gouvernment wanted to see what will happen with such a toy originally determined for themselves. The Nazis also had the first and only nerve gas bombs (Sarin, Tabun, Soman) of which tons had been produced but never been used in the end.

  • german lost becuase russia USA uk and france become allies and attack at the same time also austria and italy which was german allie left german is well.

    so think 2miilion german soldier vs 9million rusian uk USA and france

  • How did Germany loose WWII. They could build the X4 faster than we could build B17s. If only 50 percent of the B17s were lost, that would have ended accurate daylight bombing. Its still a good thing Germany did not deploy that weapon because if they drew the war out German cities would have come under nuclear attack. Germany and Japan just could not defeat America no matter what they tried.

  • and... Killed two crazy volunteers pilots... It is the one?
