USS Petrof Bay (CVE-80) was the twenty-sixth of fifty Casablanca-class escort carriers built for the United States Navy during World War II. She was named after Petrof Bay, which in turn was named in 1928 after Ivan Petroff, a Russian Alaskan who served as a special census agent for the 1880 United States census. The bay is located within Kuiu Island, which at the time was a part of the Territory of Alaska. The ship was launched in January 1944, commissioned in February, and served in support of the Mariana and Palau Islands campaign, the Philippines campaign, including the Battle off Samar, the Battle of Iwo Jima, and the Battle of Okinawa. She was decommissioned in July 1946, when she was mothballed in the Atlantic Reserve Fleet. Postwar, she participated in Operation Magic Carpet. Ulti
