The IT-1 was a Soviet cold war missile tank based around the hull of the T-62. The tank fired specially designed 3M7 Drakon missiles from a pop-up launcher. It saw very limited service between 1968 and 1970. The large deadzone around the tank created by the missiles' minimum range combined with the limited amount of ammunition carried made it unpopular with the military. Additionally the 520 kilograms of guidance equipment needed for the missile was impractical. Eventually they were converted into recovery vehicles.
