The M50 series protective mask, officially known as the Joint Service General Purpose Mask (JSGPM or JSGPM/M50), is a lightweight, protective mask system consisting of the mask, a mask carrier, and additional accessories. It was adopted by the U.S. military in 2006 and is manufactured by Avon Rubber, [1] the rubber-producing department of Avon Protection. There are two variants, the M50, for ground and shipboard use, and the M51, for ground vehicle use.[2]

The mask was designed to incorporate state-of-the-art technology to protect soldiers from current and anticipated threats from all types of weapons of mass destruction. It is an above-the-neck, chemical-biological (CB) respirator that protects against battlefield concentrations of CB agents, toxins, toxic industrial materials, and radioactive particulate matter.

The M50/51 masks replace the M40 field protective mask and M42, the MCU-2/P series masks, and the M45 of the Land Warrior Program.[2]

History

The M50 series mask entered service in December 2006.[3][4] In July 2014, Avon Protection received a contract to supply 135,000 M50s for $33 million.[5] In March 2016, it was announced that 166,623 M50s were purchased by the Department of Defense (DOD) under a $42 million contract.[6]

Description

The M50 series is certified to MIL-SPEC PRF-EA-10003. The mask design features improved performance against chemical and biological agents, toxic industrial chemicals, and nuclear fallout. The dual, low profile filters reduce weight and bulk while reducing breathing resistance by fifty percent over the M40 series mask. The filters incorporate a shelf-life indicator patch which changes colors from white to blue when the filters are no longer serviceable. The mask face blank incorporates self-sealing filter mounts that allow for filter changes in a contaminated environment.

The single-element eye lens gives the mask a 96 degree field of view and improved compatibility with military equipment and battlefield optical systems. The drinking system allows for greater liquid flow; however, it is not compatible with previous drinking systems and so is issued with an M50 series compatible canteen cap.

The lifetime ownership cost of the mask was reduced by fifty percent when compared with the M40 series mask due to a lower repair part count, all maintenance being completed at the operator and unit level and color coding of repair parts which decreased on-hand repair part inventory.[7]
