Status: tested 1969.
An extravehicular suit was being developed by Litton Industries, and an intravehicular suit was being developed by AiResearch Corporation. Due to budget cutbacks, it was decided to use the A7LB suit instead for Apollo J series lunar landing missions, Skylab and Apollo ASTP.
MSC terminated the development of the A9L space suit. The AL7 space suit, used in the Apollo program, would continue in use until replaced by a flight-qualified, constant-volume suit. During the Mercury program a modified version of the Goodrich Navy Mark IV suit was used. In the Gemini program a modified version of a suit developed by David Clark Company for the USAF was used. Hamilton Standard had overall development responsibility for the Apollo suit and associated portable life support system. A subcontract was awarded to International Latex Corporation for development of this suit. After suit development was completed, the production contract was awarded to International Latex, and the initial suit was designated A5L. The A6L design incorporated a thermal/ meteoroid garment. Following the Apollo fire, the suit was redesigned to eliminate flammable materials and was designated A7L (designation A8L was never used). Two hard-shell, constant-volume suits were under development, an extravehicular suit was being developed by Litton Industries, and an intravehicular suit was being developed by AiResearch Corporation. Both of the latter would be used in the Apollo Applications Program.
