A/P22S-4


American pressure suit, operational 1967. Full pressure suit replacement for the A/P22S-2, 8 sizes for use in bomber and reconnaissance aircraft. Evolved from the original MC-2 design.

The primary standard Air Force design which derived from the MC-2, the A/P22S-2 suit, evolved into a series of variant models designated A/P22S-4, A/P22S-6 and A/P22s-6A (David Clark designations for the USAF High Altitude Flying Outfit A/P22S-6 and HAFO A/P22S-6A were S1024 and S1024B, respectively). The distinctive aluminized fabric outer layer which visually characterized the experimental aircraft project MC-2 type suits was intended to provide ultraviolet and thermal radiation protection for pilots. This feature was also used on the Project Mercury suits and appeared to have captured the imagination of Hollywood's movie makers, as seemingly every science fiction film of the 1970s period depicts characters dressed in silvered 'space suits'.
