Cobham's Water Activated Mask Release (WAMR) releases an aircrew member's oxygen mask bayonet to allow for respiration in the event of a sea water landing. The WAMR provides the same critical life saving benefits as Cobham's Cartridge Actuated Cutter (CAC).  The device actuates once the aircrew member has resurfaced from a water landing. 

Key features of the WAMR include:

• Installed in the same location and manner as the standard bayonet receiver assembly
• May be installed on either side or both sides of helmet
• Device arms itself after submerging and then actuates after clearing the water
• Allows the pilot to breathe naturally while floating
• WAMR body will separate after actuation, leaving the plastic spacer and jaws on the helmet
• Will not actuate when subjected to rain or while underwater
