Pressure Suit, Apollo, A4-H, Developmental

This is a developmental spacesuit that ILC Industries made for Hamilton Standard as a proposal to NASA for an Apollo spacesuit in 1964. At the time, the two companies were supposed to be working together to design and build a spacesuit for the Apollo program. However, the relationship was strained and each side proposed their own models. This was the fourth in a series from Hamilton Standard. After the Apollo 1 fire in January 1967, NASA reorganized its spacesuit contracting and ILC went onto make the spacesuit that Neil Armstrong wore on the surface of the Moon while Hamilton made the life support and systems integration of the Moon suit.

NASA Marshall Space Flight Center transferred this spacesuit, along with gloves to the Museum after the conclusion of the Apollo program.
