Pressure Suit, Diver's, Mark V

This suit is an example of the early types of diving suits, designed and built by the Diving Equipment and Supply Company, which were the original pressure suits enabling people to work in hostile environments. Full pressure suits enabling pilots and, later, astronauts to survive in high altitudes and space were developed from suits such as this.

It is a single layer, rubberized cotton garment with lead weights to assist descent. Air was pumped from the surface through hoses.

Donated to the National Air and Space Museum by the Washington Navy Yard in 1976.
