Abstract
Abstract A weapon deliver/target interceptor (DISK) comprising a spinning right circular cylinder maneuvered by thrusters located about the periphery of the cylinder's circumference. The cylinder is guided by means of a forward looking sensor mounted on the front face of the cylinder and a guidance system which senses the rotational acceleration and precessional acceleration.
