The US Army introduced their first flying helmet, the APH-5A or APH-5 Quartermaster helmet in 1959. It was an adapted version of the US Navy Aircrew Protective Helmet no. 5 (APH-5). The change was mainly in the communications system as the US Army used the same impedance standard as the US Air Force. With the introduction of the APH-5A the number of head injuries incurred during US Army aircraft accidents was reduced by half compared to the number of head injuries incurred before helmets were used.
The early examples of the APH-5A had the same thick foam rubber edge roll as the US Navy APH-5 and usually came in white color. Later examples had thin black rubber edge beading and usually came in olive drab color.
