Cartridge Actuated Devices (CADs) and Propellant Actuated Devices (PADs) are commodity items that function as a system component. Project Director Joint Ammunition and Weapons Systems manages procurement funding of CAD/PAD items for Army Aircraft. In operation, these items release precise explosive energy to assist in Aircrew escape, fire suppression or emergency release systems. These items have a set shelf life and installed life.

The Navy is the DoD engineering and acquisition agent for all Services for CAD/PAD items.
