The David Clark Company built this spacesuit for the US Air Force, MOL (Manned Orbiting Laboratory) program in the early 1960s. The MOL program was an Air Force intelligence-gathering program that never became operational. NASA gave the suit the designation G4-C, as the suit was manufactured by the same company, using the same specifications as the Gemini G4-C suit. The David Clark Company had also been working with the Air Force to produce other high altitude pressure suits at that time
The suit is in the EV (Extra-Vehicular) configuration, and is composed of 21 layers, (including the cotton undergarment). to protect the astronaut from radiation and high-speed debris
The spacesuit was developed by NASA's Manned Spaceflight Center, Crew Systems Division, and designed and constructed by the David Clark Company of Worcester, Massachusetts, incorporating B.F. Goodrich helmet and gloves.
NASA transferred this suit to the museum in 1975.
