USS Pine Island (AV-12)

USS Pine Island (AV-12) was a Currituck-class seaplane tender built for the United States Navy during World War II. Commissioned in the final months of the conflict, the vessel provided critical support for patrol squadrons operating PBY Catalina and PBM Mariner flying boats. Its service extended through the Cold War, participating in significant early Antarctic exploration missions before being decommissioned in 1967.

Construction and commissioning

The ship's keel was laid down on 16 November 1942 at the Todd Pacific Shipyards facility in San Pedro, California. Launched on 26 February 1944, the vessel was sponsored by Margaret Langdon, the wife of Rear Admiral John L. Hall Jr.. After completing fitting out and initial sea trials, *Pine Island* was formally commissioned into U.S. Pacific Fleet service on 26 April 1945 under the command of Captain H. H. Caldwell.

Service history

Following its shakedown training off the coast of Southern California, the new seaplane tender was assigned to Task Force 38, part of the powerful Third Fleet under Admiral William F. Halsey Jr.. Its primary role was to serve as a mobile base and maintenance facility for long-range maritime patrol aircraft, providing fuel, ammunition, repairs, and crew accommodations. This capability was vital for extending the reach of U.S. naval aviation across the vast expanses of the Pacific Ocean.

World War II operations

*Pine Island* arrived in the Pacific Theater in July 1945, as Allied forces were conducting the final campaigns against Japan, including the Battle of Okinawa and the intensive bombing of the Japanese home islands. The tender supported patrol aircraft conducting anti-submarine warfare, search and rescue, and photographic reconnaissance missions. It was operating with the Third Fleet near Okinawa when hostilities ceased in August 1945, and it subsequently assisted in early occupation activities.

Post-war service and fate

After the war, *Pine Island* was briefly decommissioned in 1950 but was quickly recommissioned for service in the Korean War, where it supported patrol aircraft operations. Its most notable post-war service came with Operation Highjump, the massive 1946–1947 U.S. Navy expedition to Antarctica led by Rear Admiral Richard E. Byrd. The tender served as a flagship and base for the expedition's PBY Catalina aircraft. It continued in various support roles through the 1950s and 1960s before final decommissioning on 1 July 1967. The ship was struck from the Naval Vessel Register the same day and sold for scrap in 1971.

Awards and legacy

For its World War II service, USS *Pine Island* was awarded the American Campaign Medal, the Asiatic-Pacific Campaign Medal, and the World War II Victory Medal. Its participation in Operation Highjump contributed significantly to the cartographic and scientific understanding of the Antarctic continent. The ship's name is commemorated in Pine Island Glacier in Antarctica, which was mapped by aircraft from the tender during the historic expedition.
