Abstract

A deceleration device for a submunition unit includes a cartridge releasably attached to the submunition unit. A releasable package including at least one pocket is disposed in the cartridge and is connected to the cartridge by a packaging line. An auxiliary parachute and a rotation parachute are disposed in the cartridge, with at least the rotation parachute being accommodated in the at least one pocket of the releasable package and the auxiliary parachute being disposed in a pocket separate from the at least one pocket. The auxiliary parachute is connected to the cartridge and the rotation parachute is connected to the submunition unit. A deployment mechanism causes the auxiliary parachute to be deployed in advance of the rotation parachute after the cartridge is released from the submunition unit and the rotation parachute to be deployed after the cartridge is decelerated by the auxiliary parachute for decelerating the submunition unit.
