This full pressure suit was not built for flight, but for the purpose of testing some advanced design features. These features included a pressure-sealing closure, mobility joints in the shoulders, hip and waist, knees, ankles, elbows and wrists. The suit included an advanced design thermal grid cooling garment, capable of withstanding a static proof pressure of 10.0 psig for 15 minutes. An additional feature was the convoluted joint system for movement, as required by the NASA contract.

The suit is a modification of a model S-1026 IVA suit, and considered to be an Apollo-era advanced EVA concept suit. It was developed during the Phase I Apollo period, and delivered to the Manned Spacecraft Center in Houston upon completion. While in Houston, it underwent a variety of tests, before being transferred to the National Air and Space Museum in 1982.
