Project history

This project was inspired indirectly by the British X-Craft of the Second World War, one of which visited the USA specifically to provide design references. The original propulsion paint used hydrogen peroxide, this craft being the sole US fruit of the postwar Allied peroxide programme. She was built in 1954-55, but suffered an internal explosion in February 1958, which broke her into three pieces. Rebuilt at Philadelphia, she rejoined the Navy 14.12.1960 as a special test craft at NSRDC, painted orange.
