The USS Myrmidon (ARL-16) was a distinctive vessel originally laid down as a United States Navy LST-542-class tank landing ship, designated LST-948. She was constructed at the Bethlehem Hingham Shipyard in Massachusetts, with her keel laid on August 25, 1944. The ship was launched on September 28, 1944, and sponsored by Mrs. Marguerite Ross. Initially placed in reduced commission on October 19, 1944, she was transferred to Jacksonville, Florida, where she was decommissioned on November 10, 1944, for conversion into an Achelous-class repair ship—one of 39 such vessels designed specifically for repairing landing craft. This conversion was carried out by Merrill Stevens Shipyard, and she was officially commissioned as ARL-16 on March 9, 1945. Physically, as an Achelous-class repair ship, she was equipped to provide maintenance, repair, and provisioning services to landing craft during World War II, playing a vital support role in amphibious operations. After her shakedown along the East Coast, she departed Norfolk, Virginia, on April 10, 1945, headed for the Pacific theater. She arrived in San Diego later that month, then proceeded to Pearl Harbor via San Francisco with cargo, arriving on May 19, 1945, to join the Amphibious Force of the Pacific Fleet. Myrmidon’s operational duties took her to Iwo Jima, where she arrived on June 22, 1945, during the final stages of the Battle of Iwo Jima. There, she played an essential role in repairing, disbursing, and provisioning ships supporting the ongoing campaign. Following Japan’s surrender, she continued her service throughout the Pacific, operating from the Marianas to Pearl Harbor, assisting in post-war efforts. Late in 1946, she returned to the Gulf Coast, entered a reduced service status in January 1947, and was decommissioned at Orange, Texas, on July 7, 1947. She was then placed in the Atlantic Reserve Fleet, where she remained until her name was struck from the Naval Vessel Register on April 1, 1960. Subsequently, she was sold to River Equipment, Inc., and later resold to the Dravo Corporation and the Avondale Shipbuilding Corporation. Her ultimate fate remains unknown.
