Abstract: A fin stabilized subammunition body including a target detection device and being ejectable in a target area from a spin stabilized artillery carrier projectile. The target detection device includes a fixed sensor for detecting a target and producing target signals representing characteristics of the detected target, a reference platform for producing inertial reference signals, and a controller connected to the fixed sensor and the reference platform for producing drive control signals for selectively actuating a plurality of microreaction drive mechanisms arranged for producing transverse acceleration forces for aligning the body with a detected target.
