A Sea Control Ship (SCS) is a type of small aircraft carrier designed and conceptualized by the United States Navy in the 1960s. The SCS was designed due to severe cuts in Navy spending, requiring a cheap, flexible platform that could deliver air power to the field without resorting to an enormous aircraft carrier. Sea Control Ships were designed to carry a mix of fighters and helicopters, and the first SCS vessels were the Iwo Jima-class amphibious assault ships. The SCSs were smaller than most large aircraft carriers, and the concept was seized upon by nations wanting cheap aircraft carriers, most notably Spain, whose flagship Principe de Asturias class was based on the SCS design. Modern examples of SCS-type vessels include the British Ocean class, and the U.S. Tarawa and Wasp classes, members of which all of which operated in the Persian Gulf carrying a mixture of helicopters (and in case of the Wasp and Tarawa classes, also STOVL/VTOL attack aircraft) and Marine equipment (tanks, armored vehicles, landing craft, etc.). Mostly these days, navies do not operate dedicated SCSs but prefer to operate more flexible platforms that can assume the role of an SCS.
