The HGU-20/P Robert Shaw Controls Co. helmet differs from other protective flying helmets in that it is a closed type with a built-in oxygen system. It was intended to eliminate the need for an oxygen mask and to provide improved helmet retention under windblast. The helmet entered fleet testing in 1965 as was popular with attack squadron aircrews. However, it was withdrawn from service in 1971 because it restricted the pilot's vision in combat.
