USS Admiralty Islands (CVE-99) was the forty-fifth of fifty Casablanca-class escort carrier built for the United States Navy during World War II.

The ship had a cruising range of 10,240 nautical miles (18,960 km; 11,780 mi) at a speed of 15 knots (28 km/h; 17 mph).

[7][8] Her construction was awarded to Kaiser Shipbuilding Company, Vancouver, Washington under a Maritime Commission contract, on 18 June 1942, under the name Chaplin Bay, as part of a tradition which named escort carriers after bays or sounds in Alaska.

She was launched on 10 May 1944; sponsored by the wife of Vice Admiral Homer N. Wallin; transferred to the United States Navy and commissioned on 13 June 1944.

[1][11] Upon being commissioned, Admiralty Islands got underway, on 2 July 1944, from Astoria, Oregon on a shakedown cruise down the West Coast to San Francisco.

She returned to Pearl Harbor, where she transported aircraft and personnel back to the West Coast, arriving at San Francisco on 24 August.

There, she loaded more aircraft and military passengers, and sailed westwards, touching Pearl Harbor on 24 December.

[12] She took on a complement of sixty-one replacement planes at Pearl Harbor, and she left port on 2 February, bound for the waters off of Iwo Jima, in support of the planned landings there.

On 18 April, Admiralty Islands suffered an operational casualty from a Grumman F6F Hellcat fighter crashing into her flight deck.

As the pilot applied full throttle, its tail hook caught the No 5. arresting wire, forcing the aircraft onto a gun mount, splitting the fighter in half.

Whilst she was moored for repairs, the other three escort carriers of her task group endured Typhoon Connie, which transited northwards through the waters east of Okinawa.

As the plane circled the carrier, refusing the order to ditch and struggling to jettison its belly tank, the rest of the aircraft had already been stowed beyond the forward wire barriers.

As the plane caught the first arresting gear, the gasoline tank detached, skidded down the flight deck, hit a crewman, and exploded, killing the man.

The explosion sprayed burning gasoline onto the parked planes, and set alight the wooden flight deck.

As a result of the damage sustained from this accident, Admiralty Island was ordered to detach from the task group and to retire to the West Coast.

Nonetheless, repairs were conducted, and on 1 September, she was assigned to join the "Magic Carpet" fleet, which repatriated servicemen from throughout the Pacific.

She was struck from the Navy list on 8 May, and the hull was sold on 2 January 1947 to the Zidell Machinery and Supply Company of Portland, Oregon.
