The USS Endurance (ARDM-3) was originally constructed as ARD-18, a non-self-propelled auxiliary floating drydock built in 1944 by the Pacific Bridge Company in Alameda, California. Designed to provide repair and maintenance support to naval vessels, ARD-18 played a vital role during World War II, serving in the Asiatic-Pacific Theater. Its operational area included key naval bases such as Guadalcanal, Ulithi, and Leyte-Samar, where it serviced a variety of ships, contributing significantly to the logistical and repair capabilities of the U.S. Navy during the war. Following the conclusion of hostilities, the vessel underwent extensive modifications around 1967-68 at the Norfolk Shipbuilding and Drydock Corporation. During this period, it was lengthened by adding a 100-foot (30-meter) midsection, which enhanced its capacity and operational versatility. Additionally, an extra deck was constructed above the uppermost crane deck, further expanding its functional space and repair capabilities. These modifications marked its transition from a standard drydock to a more capable auxiliary repair vessel. In recognition of its evolving role, the vessel was redesignated as the Medium Auxiliary Repair Dry Dock Endurance (ARDM-3). This designation reflected its enhanced capacity to accommodate and service larger naval vessels, including various combatants and support ships. The USS Endurance (ARDM-3) served the U.S. Navy until her retirement in 1995, marking over five decades of active service. Throughout its operational life, the vessel exemplified the importance of floating drydocks in naval logistics, providing essential repair services in both wartime and peacetime contexts. Its modifications and extended service record underscore its significance in maintaining fleet readiness and supporting naval operations across the Pacific and beyond.
