This helmet has the designation A-1-C, and was a modification of the Gemini G-4-C helmet. This helmet was worn by various astronauts during training sessions prior to the Apollo missions, though was never used during those missions.

The helmet was constructed of fiberglass and epoxy resin and was molded to fit directly into the neck bearing disconnect. A Plexiglas visor, capable of being raised for access, was attached with pivots, and when lowered into pressure sealing position, it locked in place with a latch. Communication devices with suede-covered ear pads were incorporated into the helmet.

The A-1-C helmet had a visor protector fabricated of cycolac protecting the visor when it was in the open position. There was a channel running down the middle of the protector to allow the latch assembly to slide back with the visor.

Transferred to the national Air and Space Museum from NASA in 1973
