The S-2 partial pressure suit evolved originally for use in bomber aircraft although it was also used in experimental aircraft test projects. In 1951 the US Air Force authorized limited production of the S-2 suit for certain projects, but it was the T-1 suit which figured most prominently in the first high altitude jet and rocket propelled aircraft experiments of the late 40s and early 50s
