Abstract: A target activated spin stabilized projectile fired in a sustantially flat rajectory utilizes a pair of diametrically disposed antennae electrically coupled to a 35 gigahertz radiometer to scan a target area. Upon detection of a target within the proximity of the projectile's flight path logic circuitry of the radiometer generates a signal activating one branch of a dual out-of-line ignition system. The selected ignition branch fires a high speed self-forging slug from a target aligned side of a Miznay-Shardin type warhead vertically downward into the "soft" top side of the detected target.

Abstract: A fuze containing a bimetallic spring delay module, which includes a bimelic Belleville spring and a pyrotechnic charge for heating the spring. The spring is capable of inverting by heat from the pyrotechnic charge and of reverting on cooling, whereby the spring provides a mechanical action by means of an element attached thereto, such as a firing pin, switch, an arming slider or rotor, etc.

Abstract: A plural mode fuze with a bimetallic spring delay module providing delay ing, impact functioning, random time detonating and/or self-destruct functioning of a munition. The fuze includes a cup containing a detonator and a safing and arming means, a striker cup slidably nested therein, and an intermediate compression spring for moving the cups oppositely from a safe position to an armed position. The striker cup contains a fixedly mounted bimetallic spring delay module, which includes a bimetallic Belleville spring containing a firing pin, a pyrotechnic charge for heating the spring, a heat sink and thermal insulation means. The fuze has a means for locking the Belleville spring when it inverts by heat from the pyrotechnic charge, whereby the Belleville spring overcomes the compression spring.
