This is a modified Advanced Extra-Vehicular Suit (AES) that was constructed in the late 1967 or early 1968. AES suits were developed for long-duration lunar activity, but were not used as the Apollo program ended. The exterior is of Chromel-R, a woven stainless steel used as a protective coverlayer on parts of Apollo suits, gloves and boots. This is the only suit known to have been covered with Chromel-R. At the time the fabric cost several hundred dollars per yard. Despite its protective characteristics, engineers decided that the cost was prohibitive.
NASA transferred this suit to the museum in 1976.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
