Crash Ballistic Protective Flying Helmet, Nylon Outer
Shell was studied already in 1962 by the US
Army in response to early combat experience in SEA with the APH-5 standard
Development and testing lasted until end of 1965, leading to an helmet shell
made of ballistic-resistant Nylon fabric, laminated with phenolic resin. The
result was a better fitting and bullet-proof helmet, but the weight increased up
to 1,5 Lbs. A single dark or clear visor was operated to a classic screw knob.
Due to shortages and slow delivery, only about 5000 AFH-1s reached the troops
in Viet-Nam by mid 1967, and deliveries were completed by end of 1969.
Meantime the APH-5 was still used in combat, although the US Army declassed it
to the status of "stateside use only".
