USS Ranger (CV-4) was an interwar United States Navy aircraft carrier, the only ship of its class. As a Treaty ship, Ranger was the first U.S. vessel to be designed and built from the keel up as a carrier. She was relatively small, just 730 ft (222.5 m) long and under 15,000 long tons (15,000 t), closer in size and displacement to the first US carrier—Langley—than later ships. An island superstructure was not included in the original design, but was added after completion.

Operation Torch was an Allied invasion of French North Africa during the Second World War. Torch was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to begin their fight against Nazi Germany and Fascist Italy on a limited scale. It was the first mass involvement of US troops in the European–North African Theatre and saw the first large-scale airborne assault carried out by the United States.
