Abstract: A submunition unit provided with a rotary parachute (3) as the sole parachute. The parachute, after release, initially is unable to be fully deployed due to reef loops (16) provided on the rigging lines (15) and held by a releasable holding device arrangement (4, 5, 6) and therefore acts as a deceleration and stabilization parachute at high flight velocities. The reef loops (16) are released after a predetermined period of time to permit the rigging lines (15) to fully extend and parachute (3) to become fully deployed or opened.

Abstract: A projectile comprising a projectile body having a rear end; and a deceleration element composed of a sheet of material at the rear end, the deceleration element having an edge region and being deployable from a folded condition to an expanded condition with the aid of rotation of the projectile, the deceleration element, when in the expanded condition, having the general form of a disk with a periphery defined by the edge region and being effective for decelerating the projectile, and wherein the deceleration element is constructed such that the edge region has a higher mass density than the remainder thereof.
