The invention extends the operational envelope of towed bodies at high altitudes and at high dynamic pressures. It features fins with large span/chord ratios, compactly stowed along the body surface, pivotally swept back with their chord broadside to the airstream. These fins generate high drag forces and large stabilizing and damping moments, even at supersonic speeds. Sweepback angles, controlled by elastic restraints, increase as fin loads increase. This minimizes variations in cable tension, even in maneuvers. Fin drag forces can also extend telescopic body elements. Fin settings can also generate vertical or lateral forces to bias decoy position.

A body with deployable fins comprising: a missile-shaped body; a plurality of elongated fins, folded against the body in stowed position; pivot means connected between the fins and the rear of the body for rotating the fins about the rear of the body upon deployment; means connected between the body and a free end of each fin to restrain a deployed fin in a sweepback position relative to the body; and a tow cable connected to a point of the body, generally above and forward of the center of gravity.
