The WHSS provides a safe and efficient handling and stowage system that permits a minimum of crewmembers to store torpedos, missiles, and depth charges in a shipboard magazine and to safely and quickly transfer them from replenishment dollies to or from the ship's weapons magazine. It includes a pneumatically-operated, bi-rail hoist with sway braces capable of stabilizing a weapon in heavy seas.

• Aluminum alloy, 6061-T6
• Shock tested to Mil-S-901D
• Blast shields
• Captured hardware
• Universal chocks that can be used with a variety of weapons
