The USS Alcor (AD-34) was a unique destroyer tender in the United States Navy, originally constructed in 1928 as the SS Dixie by the Federal Shipbuilding and Dry Dock Company in Kearny, New Jersey. Acquired by the Navy on March 3, 1941, from the Southern Pacific Steamship Company, she was converted for naval service at Bethlehem Steel's plant in Baltimore and commissioned as USS Alcor (AG-34) on September 4, 1941. Initially, she departed on December 7, 1941, heading to Casco Bay, Maine, where she completed her shakedown and became the flagship of Commander, Train, Atlantic Fleet. Shortly thereafter, she was reclassified as a repair ship (AR-10) on December 22, 1941, and spent over 30 months at Norfolk, Virginia, performing essential repair and maintenance duties for warships. Her role was critical during this period, ensuring fleet readiness during the early years of World War II. On July 4, 1944, Alcor moved to Casco Bay, becoming the flagship of Commander, Destroyers, Atlantic Fleet, and served there for about five months. Her designation was changed again to AD-34 on November 6, 1944, marking her as a destroyer tender. In January 1945, she transitioned to the Pacific Theater, transiting the Panama Canal and arriving at Pearl Harbor on February 3. She then proceeded to the Philippines, arriving at Leyte on June 26, where she provided repair services for various ships under Service Squadron 10 amid the final stages of World War II. Following the Japanese surrender in August 1945, Alcor moved to Okinawa and later to Japan, operating from Sasebo and Yokosuka through March 1946. She returned to the United States, arriving in San Diego on June 3, 1946, and subsequently Norfolk. The vessel was decommissioned on August 5, 1946, sold the following day, and struck from the Naval Vessel Register later that month. She was scrapped in 1950. Throughout her service, USS Alcor played a vital role in fleet logistics, providing maintenance and repair support across both Atlantic and Pacific theaters during World War II, exemplifying the importance of auxiliary ships in naval operations.
