Could the United States build a smaller conventional CATOBAR carrier to replace combat losses in a major war?
Short answerYes, but the estimate is still roughly two and a half to three years, so it would complement faster emergency conversions rather than provide an immediate replacement.
NotesA smaller American CATOBAR carrier is accepted as a possible wartime response, but the construction estimate is still roughly two and a half to three years. World War II light fleet carriers illustrate the delay even when builders could adapt an existing design, described here through HMS Unicorn. Reworking an amphibious-ship design would help with design preparation without eliminating the interval between laying a keel and commissioning a ship. The Queen Elizabeth class is proposed as an available basis for a conventionally powered carrier, including a CATOBAR design associated with the French requirement. Such options address replacement over several years, while merchant conversions remain the faster emergency expedient.
