The DH-5 was developed by Gentex in the mid 1950s as a USAF version of the US Navy DH-5-3 to replace the P-4 variants. Its shell was constructed of a fiberglass cloth reinforced with epoxy resin and internal suspension system adjustable by external straps was used.
The DH-5 incorporates the earphone so no internal cloth helmet was used, the oxygen mask was secured to fast snap bottoms on external leather tabs. The external visor was moved and secured by means of two lateral tracks system.The USAF chose the HGU-2/P so this helmet never reached the operational service.
