The USS Larch (AN-21/YN-16) was an Aloe-class net laying ship constructed for the United States Navy during World War II, designed primarily for laying, maintaining, and removing anti-submarine and anti-torpedo nets. She was laid down on October 18, 1940, by the Marietta Manufacturing Company in Point Pleasant, West Virginia. The vessel was launched on July 2, 1941, and officially placed in service on December 13, 1941. Initially assigned to the 3rd Naval District, USS Larch operated out of New York Harbor, conducting antisubmarine warfare patrols. Her early service involved patrolling and supporting net operations aimed at safeguarding vital naval and merchant shipping routes. On April 12, 1942, she departed New York City for the West Indies, arriving in Trinidad two weeks later. Her duties in the Caribbean included patrol and net-laying operations, which were crucial for protecting Allied maritime interests in the region during the war. USS Larch was placed in full commission at Trinidad on December 13, 1942, and was reclassified as AN-21 on January 20, 1944. Throughout her wartime service, she played a vital but often understated role in maintaining the security of Allied shipping lanes by deploying and servicing anti-torpedo and antisubmarine nets across the West Indies. Notably, on January 10, 1945, she participated in the salvage of a Pan American Clipper aircraft that had crashed in the Gulf of Paria, Venezuela, recovering six bodies and the fuselage. After the war, USS Larch returned to Norfolk, Virginia, arriving on October 12, 1945, and was decommissioned there on June 28, 1946. She was struck from the Navy List on March 5, 1947, and subsequently transferred to Turkey under the Military Assistance Program on May 10, 1948, where she served as AG-4 (P-304) in the Turkish Navy. The USS Larch's service exemplifies the critical support roles played by auxiliary ships in maritime defense and anti-submarine warfare during World War II.
