Flight Helmets
USAF late 40s-50s



The development of Jet aircrafts during the late 40s led to understand that the flight headgear used so far on propeller aircraft was not any more suitable to adeguatelly protect the pilots during the new typic flight and combact performances of the jet aircrafts. In particular the increasing noise of the aircraft engine and the utilization of ejection seat system at higher speeds and altitudes led to the development of rigid shell helmet which provided much more noise attenuation as well as head protection in case of high speed bail-out or an emergency crash.
After the early non standardized "Transitional" helmet the first standard issue Air Force Helmets were of the P series from P-1 to P-4B. At the end of the 50s a new helmet design was introduced: the APH-2 with its innovative visor mechanism and relevant protective housing.

Early "transitional" rigid flight helmets

During the late 40's the early rigid flight helmets were still not standardized, some of those were customized by the pilots themself or constructed by private aircraft company personnel for their own use. These "transitional" helmet were manufactured using elements coming from WW II softs flight headgear modified with rigid parts coming from helmets used on army tanks, race-cars, or football game.
Even as these "transitional" helmets were finding application in the first US jet, research on hard protective helmets incorporating communications and oxygen mask attaching system, was being conducted by the Air Force's Wright Patterson Personal Equipment Laboratory (PEL), Clothing Branch, under the umbrella of the Engineering Division of the Material Command, Northrop Aviation's Dr. Charles Lombard, and Private companies such as Consolidated Vultee Aircraft Corporation in San Diego, California. these research bring to development of the ancestors of the early standard flight helmets.
Modified tank helmet:
On April 19, 1945 Air Corps Maj. Carl Arnold of the TSEAL-5C (Clothing Branch) were requesting tank helmets, ordnance G-9, for PEL. They were an interim measure to be used for developmental work for use as crash helmets for the Air Corps. The development work on crash helmets (modified G-9 tank helmets) for use in the Lockheed XP-80 project was accomplished by the PEL in conjunction with the plastic division of the Continental Can Company, Inc. Chicago, Illinois. On January 8, 1946 a report from the AAF Board did not recommend the modified tank helmet for standardization but it continued in service for a while yet until replacements were available.
Style 1 helmet:
By July 5, 1945 the Chief of Material Division sent another developmental sample protective helmets developed by Captain J.F. Hooper of the PEL to the AAF Board, Orlando, Florida. By October 1945 Mr. Lagrand Daly of the Paramount Rubber Company was sending another new type of helmet mold for evaluation at the PEL. As we can see many helmets were being tested at the same time by the PEL. Meanwhile by Oct. 31, 1945 Col. Haskins was sending a developmental helmet sample to the Chief Test Pilot, Jack Wodams of the Bell Aircraft Corporation in Buffalo, New York, for the XS-1 project. Also Tony LeVier, Chief Test Pilot of the Lockheed Aircraft Corporation in Burbank, California, received one. In a letter of the 29 April 1946 the designation STYLE 1 was coined to the new helmet that the PEL has developed. Seventy-five were forward to Randolph Field Texas for evaluation in the P-80 type aircraft. Individual fitting of these helmets to students and instructors range in head sizes from the smallest required size up to approximately size 7-3/8 may be fitted. It is suggested the following method of fitting be used in order to provide the greatest comfort and protection to each individual. The Bell Company were conducting a series of experiments with the XP-83 aircraft and made a series of recommendations by A.M. Johnston, Chief test pilot, to the Material Command (PEL) in modifying the Style 1 after an accident on Sept 4, 1946 by Mr. C.L. Fay. Among the recommendations were the built –in earphones, insufficient lamination in the helmet shell and a corner of approximately 70 degree angle in the crown and back drop edge. Because the Style B helmets were under development no changes would be done to the Style 1 helmet according to the reply from PEL.
Style B helmet:
As mentioned above On January 8, 1946 a report from the AAF Board did not recommend the modified tank helmet for standardization. February 7, 1946 the PEL asked a number of companies to fabricate a helmet (the one that would later be designated Style B). This new helmet has a shell moulded from laminated 8 ounce enamelling duck impregnated with phenolic resin. The shape is similar to that of a football helmet which provides maximum coverage of the head, consistent with good visibility, head movements, goggle type B-8 and oxygen mask integration. The outside surface is a metallic copper spray, applied by scuffing the surface and painting with a mixture of clear lacquer and brilliant copper flake powder, which has a high thermal insulation value. This finish is easily scratched, but is not inclined to chip off as readily as the electro-plated copper finish. Space within the helmet provide for air circulation. The edge of the shell, has a plug strip of ¼ inch thick foam rubber cemented to the inside adjacent to the edge, is bound with 1/8 inch diameter rubber tube which has been split length-wise and a 1/32 inch thick strip of Buna sheeting. Included in the binding around the corners of the flaps are cut-to-shape neoprene sheeting for retaining the earphones mounting.
Style B-1 helmet:
By July 29, 1947 the Paramount Rubber Company was manufacturing the B-1 flying helmet. Despite the fact that a test preliminary report had not been received from NACA, orders of production and distribution had already started. Pre-standardization testing would be conducted by Air Proving Ground Command, Florida and deliveries expected to start approximately in July 15, 1947. Due to the urgent requirement existing for head protection to pilots of high speed aircraft, this helmet was initially distributed to the AAF Fighter units. On 20 August of 1947 a letter was sent to the Commanding General, Army Air Force, Washington D.C., Research and Engineering Division from Colonel Arnold T. Johnson, Air Corps, Chief, Engineering Standards Sections, Engineering Division for the ´ Authority for Change of Status of Equipment´ now then P-1 (Does this mean that the STYLE B-1 was standardised as the P-1?). Standardization took effect on September 1947.

P-1

The P-1, introduced in 1948 and made by Switlik Parachute Co. and Paramount Rubber Co. was the first USAF standard hard flight helmet for fighter aircraft. The P-1 initially used the type HS-38 headset, somewhat later changed to HS-38A.
The P-1 shell was constructed of pressure and heat molded laminated cotton duck fabric that had been saturated with phenolic-resin (similar to Bakelite). This helmet did not have a fixed (rivetted) chin strap as did later upgraded versions, but instead could be secured to the head through use of a chin cup that snapped onto the lowest of the snaps on the oxygen mask mounting tabs. A-13A or A-14 oxygen mask were worn together the P-1 as well as black rubber goggles B-8.

P-1A ; P-1B

The P-1A adopted in 1949 was basically an advanced version of the P-1 with introduction of a fixed chin-strap, addition of a nape-strap, attachment of the HS-38 headset with Nylon cord. A further modification involved upgrading of the oxygen mask leather attachment tabs. Ruber farmed goggles of the B-8 type were normally used with the The P-1A which in some cases has been later retrofitted with P-3 style visor. The P-1A was utilized with A-13A and A-14 oxygen mask.
The P-1B flight helmet was identical in all respect to the P-1A. it was only created through a change in designation nomenclature.

P-2

The P-2 was a limited, non-standard research prototype designed and developed by Wright-Patterson Aircrew Equipment Laboratory based on the US NAVY H-3 and H-4 helmets approach of utilizing a soft fabric inner helmet to hold the communications headset under the hard protective shell. The P-2 utilized a P-1A hard shell over a conventional USAAF type AN-H-15 khaki poplin soft helmet. Presumably also the headset was identical to that used with the AN-H-15 helmet. Otherwise, the outer rigid shell features the same conventional design of leather/nylon head suspension system, fitted to accomodate the slightly extra protusive of the inner soft helmet. Because this helmet was very rare and almost none official informations are available some experts are of the opinion that the P-2 was actually the first P-helmet type fitted with a fixed visor.

P-3

The USAF P-3 flight helmet standardized in 1951 was developed to add wind-blast and sun-glare protection to the P-1 style helmet. In this helmet the old B-8 rubber framed goggles were replaced by a new rigid, side-latch actuated external visor assembly designated as PN 51C3632.
The P-3 helmet was virtually identical to the P-1a for most part and only the new rigid external visor distinguished the P-1A series from the P-3 series. This helmet used the HS-38 and HS-38A communication headset assembly and type U-75/U connector plug.

P-4

The USAF P-4 flight hemet 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 intercommunicationsset AN AIC-10. the new H-75/AIC headset system was added as well as a new earphone cushionsspring mounted and tethered to short nylon strings which protruted 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.

P-4A ; P-4B

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 moled cotton duck material.
In 1959 the P-4B helmet specification was issued which replaced the old "Pigtail" communication cord with a new assembly designated CX-4708/AIC. This allowed the entire earphone and mask microphone communications system to be integrated into the aircraft radio and intercom system via the oxygen mask communication cord H-149/AIC. The P-4A and P-4B were used with MS22001 or MBU-3/P oxygen mask attached to the snaps on lateral leather tabs which was later replaced by Hardman external oxygen mask "Christmas tree" receivers.

A-13

The A-13 was intended for use in multi-engine and "low & slow" aircraft. It was used in the mid 1950s on B-36 Peacemaker and the B-29 bombers. The A-13 original version featured the HS-38 headset & chamois-covered earphone cushions (identical to early P-1 and P-3 helmets) and was constructed of a light to medium brown leather. The later version was constructed of gray leather and used the H-75/AIC type headset identical to that in the P-4 hardshell helmet.This helmet was utilized with A-13A or A-14 oxygen mask.

"Bill Jack" Model D-8/D-10

In the mid 50s the Bill Jack Scientific Instrument Co. developed a flight helmet shell used for different typology of flight helmets. Some of these like the SPH-1 and SPH-2 were intended for use on rotary-wing aircraft. some "Bill Jack" design shell helmets retrofitted with P style visor were also used on jet aircraft. These typology of flight helmets was later manufactured by others company as CalMil, Flight Sound, Protection inc. taking the designation of D-8 and D-10. These flight helmets incorporate the communication earphone and in the early version an external row of snaps of each side of the shell (later replaced by bayonet retainers) to accomodate the oxygen mask.

DH-41

The Gentex DH-41 was a prototype helmet intended for use in multi-engine and "low & slow" aircraft. It was used for some flight test by USAF during the 50s as for instance by the crew involved in the aerospace research parabolic flights. This helmet was compoused by a cloth inner helmet incorporating the communication system attached by screws to an upper fiberglass hard shell with the suspension system. The advanced versions of this early prototype were named DH-41-1 and DH-41-2 and have been used by the Candian Air Force in several type of aircraft including high performance fighters.

The MB-4 was identical to the P-4 except that it lacked the rigid external visor.This helmet was intened for use in non-high performance aircraft, such as slower, multi-crewed bombers, transport, and utility aircraft, in which the extra protection of a wind-blast visor was not needed.
Although the rigid wind-blast visor was not standard to the MB-4 specification, the external visor P-4A style was frequentelly added. The MB-4 was utilized with MS22001, MBU-3/P and MBU-5/P oxygen mask.

TOPTEX and 4AM SUPER TOPTEX

The TOPTEX flight helmet produced by Protection Inc. Division of Mine Safety Appliance Company was typically used by Test pilots since the middle of the 50s through the 70s, as well as in some USAF squadrons. This helmet has the unique and typical external visor locking mechanism with cental track and do not utilize the chin stap. In the TOPTEX early configuration the external visior was not present and the oxygen mask was secured to the snaps on leather tabs replaced in the later versions by Hardman external oxygen mask "Christmas tree bayonet" receivers. External boom mounted microphone, clear visor or customized mask receivers were in some cases also installed.
The 4AM SUPER TOPTEX was developped during the 80s by Protection Inc. and Gentex as a lightweigh variant of the standard TOPTEX. It had only 4 layers of fiberglass while the standard shell has 8. The SUPER TOPTEX was also normally equipped with bungee visor or HGU-53/P style visor

DH-5 / DH-5-3

The DH-5 was developed by Gentex in the mid 50s as USAF version of the US Navy DH-5-3 to replace the P-4, P-4A and P-4B in the USAF inventory. 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.

HGU-2/P

The HGU-2/P was the first USAF helmet incorporating the visor housing. Its shell was constructed of a fiberglass cloth reinforced with epoxy resin. The HGU-2/P incorporate the H-149/AIC headset identifiable by the MX-2088/U earcup, the double nylon sting attachment and the microphone plug hanging loosely from the side of the helmet. The HGU-2/P was used with MS22001 or MBU-3/P oxygen mask which was attached to snaps on leather tabs on HGU-2/P early configuration, Hardman "Christmas tree bayonet" or straight T bayonet receiver have been installed in the later version whose were mainly utilized with MBU-5/P oxygen mask.The neutarl grey or trasparent visor was moved and locked in the early HGU-2/P by a round knob incorporating a push buttom locking device, classical "star" locking knob was present in the later configuration.

Very interesting early HGU-2/P with black edge roll, visor type with hooked-edge with the associated L-bracket stops, P-4 style of earphone mounting, but instead of the brown phenolic-colored cord studs like the P series, it appears to have the later HGU nickel snap studs as used on the later HGU-2A/P.The chin and nape straps appear to be USN APH types, also the the liner is very unique, using a blue surface material.
This helmet very likely represent the earliest version of HGU-2/P helmet customized with some later elements like the Christmas tree bayonet recivers and the chin and nape straps.
