M45 Aircrew Chemical-Biological Mask System (original) (raw)

Recently Type Classified-Standard, the M45 will replace the Army's M49 Mask System. The mask provides the required CB protection without the aid of forced ventilation air while maintaining compatibility with rotary-wing aircraft sighting systems and night vision devices.

This development program was greatly accelerated by the use of the Edgewood Center's Rapid Prototyping Facility, which includes a state-of-the-art injection rubber molding press. Injection molded composite materials were used for the component parts to reduce weight and cost. These components were ultrasonically welded to the faceblank to improve the producibility of the item.
