The Joint Service Aircrew Mask – Rotary Wing (JSAM — RW) is one of five variants in the JSAM Family of Systems that provides individual respiratory, eye and head protection against Chemical and Biological (CB) warfare agents and radiological particulates for aircrews of all rotary wing aircraft except Apache. JSAM RW decreases thermal burden as compared to legacy systems. It also provides CB protection during the full spectrum of rotary wing operations including flight, immediate maintenance operations, extended flight-related ground duties, and ground escape, as well as evasion operations.


JSAM RW provides the warfighter with an above-the-neck CB protective respirator for general purpose rotary-wing aircrews. The mask is capable of being donned and doffed while in flight, provides greater comfort, less physiological burden and greater flexibility of use with man-mounted systems.
