The original P-1 hard helmet for jet pilots was introduced by the United States Air Force in March 1948. The Type P-4A was basically the same helmet with a sun visor added, improved earphones, and minor refinements to the web lining and straps. The Type MBU-5/P oxygen mask was worn with this helmet which saw extensive service with the Air Force from 1956 to 1964. It was also used by many jet pilots of NATO and other friendly nations around the world.
