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.

Casablanca-class escort carrier
Petrof Bay was a Casablanca-class escort carrier, the most numerous type of aircraft carriers ever built, and was designed specifically to be mass-produced using prefabricated sections, in order to replace heavy early war losses. Standardized with her sister ships, she was long overall, had a beam of , and a draft of . She displaced standard and with a full load. She had a long hangar deck and a long flight deck. She was powered with two Skinner Unaflow reciprocating steam engines, which drove two shafts, providing , thus enabling her to make . The ship had a cruising range of at a speed of . Her compact size necessitated the installment of an aircraft catapult at her bow, and there were two aircraft elevators to facilitate movement of aircraft between the flight and hangar deck: one each fore and aft.
One /38 caliber dual-purpose gun was mounted on the stern. Anti-aircraft defense was provided by eight Bofors anti-aircraft guns in single mounts, as well as twelve Oerlikon cannons, which were mounted around the perimeter of the deck. By the end of the war, Casablanca-class carriers had been modified to carry thirty cannons, and the amount of Bofors guns had been doubled to sixteen, by putting them into twin mounts.
