The Mark IV full pressure suit was developed for the U.S. Navy by the B.F. Goodrich Company in the 1950s. This version of the suit was manufactured by the Arrowhead Manufacturing Company as a competitor to the B.F. Goodrich suit.

The U.S. Air Force also authorized production of the U.S. Navy Mark IV for squadrons stationed in colder areas. It was tested to altitudes of 139,000 feet, and demonstrated its ability to overcome the problems associated with emergency ejection, immobility and manual pressurization.

NASA obtained this suit from the Navy for evaluation and testing purposes. NASA then transferred the suit to the Museum.
