The Surface Effect Ship, M. Rosenblatt & Son, Inc., (undated, approx 1971) (0152)
After limited effort during the late 1950s to explore the usefulness of high-speed, captured-air-bubble vehicles, the Navy established a Surface Effect Ships (SES) Project in 1965. The project was proposed to begin in fiscal year 1968. Also in 1965, a study of the SES was initiated by the Center for Naval Analyses. The technical approach subsequently proposed was for seven years of advanced development that included the construction of two 500-ton SESs, one utilizing a waterjet for propulsion and the other using semi-submerged supercavitating propellers.
