Abstract: An anti-armor weapon comprises an outer casing in which a non-explosive, armor-penetrating device, suitably a solid rod of heavy, high density metal or metal composite, is mounted. The penetrating device is mounted in a forward portion of the casing while a launch population device is mounted at the rear end for launching the weapon from a launch tube or firing barrel at a first, subsonic launch speed. A second, boost propulsion device is mounted in the casing adjacent the penetrating device for accelerating the weapon to a second, faster speed sufficient for the penetrating device to penetrate a target, and is associated with an igniter for actuating the boost propulsion device. A sensor is provided within the missile for sensing when the weapon is a predetermined distance from the target and subsequently actuating the igniter.
