The Mark IV full pressure suit was developed for the US Navy by the B.F. Goodrich Company in the 1950s. The U.S. Air Force also authorized production of the Mark IV for squadrons stationed in colder areas. It was tested to altitudes of 139,000 ft. and demonstrated its ability to overcome the problems associated with safety during emergency ejection, immobility and manual pressurization. It was a very successful design, and was modified later to become the spacesuit worn by the Mercury astronauts.

Donated to the National Air and Space Museum by Emge Aviation-Marine in 1974.
