The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slower type of aircraft carrier used by the Royal Navy, the Royal Canadian Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
USS Rabaul was a Commencement Bay-class escort carrier of the United States Navy. The Commencement Bay class were built during World War II, and were an improvement over the earlier Sangamon class, which were converted from oil tankers. They were capable of carrying an air group of 33 planes and were armed with an anti-aircraft battery of 5 in (127 mm), 40 mm (1.6 in), and 20 mm (0.8 in) guns. The ships were capable of a top speed of 19 knots, and due to their origin as tankers, had extensive fuel storage. She was delivered on 30 August 1946, but never commissioned. After spending 26 years in reserve, she was scrapped in 1973.
The Casablanca-class escort carrier was a series of escort carriers constructed for the United States Navy during World War II. They are the most numerous class of aircraft carriers ever built. Fifty were laid down, launched and commissioned within the space of less than two years – 3 November 1942 through to 8 July 1944. Despite their numbers, and the preservation of more famous and larger carriers as museums, none of these modest ships survive today. Five were lost to enemy action during World War II and the remainder were scrapped.
USS Casablanca (AVG/ACV/CVE-55) was the first of fifty Casablanca-class escort carriers built for the United States Navy during World War II.

The American victory cleared the way for the seizure of the port of Casablanca as well as the Allied occupation of French Morocco. The ship was launched in April 1943, commissioned in July, and served as a training and transport carrier throughout the war. Postwar, she participated in Operation Magic Carpet, repatriating U.S. servicemen from throughout the Pacific. She was decommissioned in June 1946, when she was mothballed in the Atlantic Reserve Fleet. She was sold for scrap in April 1947.
