LANTERN (HC-4) designed and built by the Hydrofoil Corporation, Annapolis MD, USA, this was one of the earliest hydrofoils to use electronic controls. LANTERN first flew in 1953, had tandem submerged foils, displaced about 10 tons, was 35 feet long with a beam of 22 feet. The control system was a straight adaptation of an aircraft automatic control system. The craft was unusual from another point of view: the foils, struts and hull were all the same shaped section, namely a symmetrical 24% thickness ratio NACA airfoil section. LANTERN was powered by a 200 hp Chrysler marine engine, had a takeoff speed of 14 knots, and a maximum speed in calm water of only 18 knots.
