An aerial target, which can operate either in a self-propelled or towed ciguration, is made of a lightweight, frangible foam material. When employed in the self-propelled configuration, the target includes a remotely controlled guidance system; a remotely controlled guidance system is an optional feature of the target in its towed configuration. The self-propelled target is powered by a solid fuel rocket motor encased in a non-metallic lightweight housing. In order to cause realistic destruction of the target when it is hit by a projectile, a liquid-filled cavity is included in the body of the target. When hit by a projectile, this hydraulic device ruptures and severs the target to simulate warhead detonation and to prevent further flight.

1. A frangible target with hydraulic warhead simulator for use as a target against a projectile-firing weapons platform, comprising: a body adapted for aerodynamic free flight fabricated from a predetermined frangible, lightweight foamed material having at least one predetermined liquid proof cavity therein; a liquid disposed within each cavity, minimizing ullage, serving as a medium for propogation of body-bursting shock waves caused by the impact of a projectile on said cavity; a rocket motor disposed in a rear portion of said body and made of a non-metallic, lightweight material; a guidance sensor disposed in a forward portion of said body and adapted to detect a signal transmitted by said weapons platform; a guidance system connected to said guidance sensor and acting in response thereto to control a flight path of said target to realisticallly coverge upon said weapons platform; and means for reflecting radar waves integral with said body so that said body is remotely detectable by said weapons platform; whereby upon impact of said cavity by said projectile, shock waves propogate through said liquid and lead to bursting of said cavity and catastrophic destruction of said frangible target. 2. The frangible target as claimed in claim 1 wherein said cavity is disk shaped, has a thickness of at least one length of said projectile, has faces with areas of at least 15 square inches each, and is oriented so said cavity face would appear to be a circle or an elipse with a area of at least 10 square inches if said cavity face could be seen from said weapons platform when on a converging course with said weapons platform. 3. The frangible target with hyraulic warhead simulator as claimed in claim 2, wherein said cavity is inclined relative to the pitch plane angle of said frangible target. 4. The frangible target with hydraulic warhead simulator as claimed in claim 1, wherein said liquid is chemically inert and has a high density, low melting point, and high boiling point relative to the enviroment in which said frangible target is stored and employed. 5. The frangible target with hydraulic warhead simulator as claimed in claim 1, wherein said liquid has a melting point of 0 degress Celsius or less, a boiling point of 100 degrees Celsius or greater, and a density of at least 1.00 g./ml. at 3.98 degress Celsius. 6. The frangible target with hydraulic warhead simulator as claimed in claim 5, wherein said liquid is 1-2-Ethanediol or an aqueous soltion of 1-2-Ethanediol.
