HGU-2/P, HGU-2A/P and HGU-26/P helmet identification guide HGU-2/P, HGU-2A/P, HGU-22/P and HGU-26/P helmet identification guide () latest update 28 November 2009,,,,,, The identification of HGU-2 and -26 series of helmets has been a challenge to many collectors and for very good reasons too. And then there is the HGU-22/P which causes even more confusion. Let it be said once and for all; THERE IS NO SUCH THING AS AN HGU-22/P HELMET. It is a helmet shell, not a complete helmet. The change from HGU-2/P to HGU-2A/P is fairly well defined but the HGU-2A/P has changed its appearance over the years without changing its designation.

Usually the HGU-2A/P is a single visor helmet but HGU-2A/Ps were also modified with ramshorn dual visor assemblies without changing designation. The HGU-26/P is not clearly defined in official literature but is most commonly seen as a helmet based on the HGU-22/P helmet shell fitted with the PRU-36/P side-actuated dual visor.

To make things even more confusing, the USAF did away with the HGU-2A/P designation in the mid-1970s, ending up with single visor and dual visor versions of the HGU-26/P. This guide is intended to clarify the picture a bit. If nothing else it will allow you to be confused at a higher level. The HGU-2/P and APH-5 were based on the same helmet with the USAF standardizing theirs as the HGU-2/P, the US Navy and US Army had the APH-5 and APH-5A respectively.

Just like the US Navy the USAF considered more than one design for replacing the trusty P-helmet series that had served the USAAF and USAF well from 1948 onwards. Sitar Plugin Pro Tools. General Textile Mills appears to have offered a version designated DH-5, very much like the DH-5-3 offered to the US Navy, but in the end the USAF chose the same basic MSA design as the US Navy. An example of the General Textile Mills (Gentex) DH-5 helmet which appears to have been tested by the US Air Force as a possible successor to the P-series helmets.

Very little is known about its development except for the fact that Gentex applied for patent for the visor in August 1955 and the patent went through in November 1957. A US Navy version, the DH-5-3, was tested by that service too but none of the helmets were adopted for service use. The Navy began their development around 1956 and the USAF assigned the HGU-2/P nomenclature to their version on 15 August 1957 and it was produced in accordance with the military specification MIL-H-26671 dated??? The HGU-2/P helmet seems to have been fielded from 1959 and differed from the US Navy APH-5 in a few areas. The communications and the oxygen mask tabs are different and so is the colour of the neoprene edgeroll.

Identifying features of the HGU-2/P helmet are a heavy helmet shell, often with a poorly painted finish (applies especially to helmets manufactured by Consolidated Components Corp.), thick grey or tan neoprene edgeroll, visor housing with metal strip reinforcement along the visor lock knob track, metal visor tracks, and a three-piece styrene energy absorbing liner. The HGU-2/P is equipped with an headset identifiable by the MX-2088/U earcups, the double nylon string attachment and the microphone plug hanging loosely from the side of the helmet. Original HGU-2/P helmets came with leather oxygen mask attachment tabs in tan leather with three snaps on each (early USN APH-5 helmets had black tabs with only two snaps on each). Later HGU-2/P helmets were often field modified with Hardman receivers for christmas tree bayonets or cast aluminium receivers for single bayonets. Some were also modified with the three ventilation holes in the crown, often seen as an identifying hallmark of early HGU-2A/P helmet.

Note the metal visor tracks and the metal strips along the visor lock button track. This helmet was manufactured by Consolidated Controls Corporation in December 1960.

The oxygen mask communications configuration is not correct. It should have had an early CX-4707/AIC Y-cord ending in a U-93A/U plug at the hose end. This particular helmet was acquired by the Royal Danish Air Force for test purposes which is why it does not have the usual USAF decal on the visor housing.
