USS Savo Island (CVE-78) was the twenty-fourth of fifty Casablanca-class escort carriers built for the United States Navy during World War II. She was named to memorialize the U.S. casualties of the Battle of Savo Island, which was fought as part of the Guadalcanal campaign. The ship was launched in December 1943, commissioned in February 1944, and served as a frontline carrier throughout the Mariana and Palau Islands campaign and the Philippines campaign. During the Battle of Okinawa, she provided air cover for the replenishment carrier fleet. Postwar, she participated in Operation Magic Carpet, repatriating U.S. servicemen from throughout the Pacific. She was decommissioned in December 1946, when she was mothballed in the Atlantic Reserve Fleet. Ultimately, she was sold for scrapping in February 1960.

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.
