The USAF P-4 flight helmet was standardized in 1955 as a continuation of P-3 with improved avionics in order to make helmet headset communications and oxygen mask dynamic microphone compatible with aircraft intercommunication set AN AIC-10. the new H-75/AIC headset system was added as well as a new earphone cushions spring mounted and tethered to short nylon strings which protruded through the lateral helmet walls to be secured over a rubber over a rubber lock-nut and snubber bar. The P-4 was used with A-13A/MS22001 A-14 oxygen mask. The P-4A standardized in 1957 has a new visor mechanism that replace the side latching design with a tracked visor securing system actuated by grasping a central rubber knob and pulling the visor down into position. The newly assembled P-4A helmets made use of the new fiberglass shell material that replaced the earlier phenolic resin and molded cotton duck material.
