- Caption: "Litton B1-A Advanced Extra-Vehicular Suit 1960s Litton Industries This suit was manufactured by Litton Industries, which made a series of advanced spacesuits during the early 1960s. This one is called the B1-A, of which approximately six were made. This particular suit was not equipped with a thermal cover-layer. These experimental suits were designed to maintain an almost perfect constant volume of air while enabling a full range of body motions. "The development of the spheroidal dome helmet was key in balancing the need for field of view, pressure compensation and low weight. "Althrough the Litton research program closed in the early 1970s, spacesuit research continued until the 1990s, during which period some of the most advanced and fascinating suits ever fabricated were produced."
