The BPH-1 is a U.S. Navy helmet circa 1965 used in bomber and patrol aircraft. The helmet
could also be used in other non-flying applications (Aircraft Carrier Deck crew, or SONAR
operations). The BPH-1 carried the Gentex designation DH-111 and is similar to the
Canadian DH-411 and DH-41-2. The BPH-1 was replaced very quickly by the BPH-2. The only
major differences between the two helmets are:
1- The BPH-2 has a bracket attached around each earcup to hold the earcup tightly to the
2- The Attenuation relief valve was changed for the BPH-2.
The BPH-1 is constructed of a fiberglass fabric and epoxy resin hard outer shell. The
outer shell is painted white, and when used in aviation applications, the shell normally
is dressed in reflective tape. The hemet is also equipped with a white
sytrofoam inner shell approximately ½ inch thick The outer shell is designed to provide
force distribution and penetration resistance. The BPH-1 was issued in one size with an
adjustable web suspension to provide custom fitting to a wide range of wearers. This
suspension harness is similar to the SPH-3/4 helicopter helmet suspension harness.
