The SS Mount Washington (T-AOT-5076) was a large American transport oiler with a notable service history. Originally constructed in 1963 for commercial purposes, the vessel was later incorporated into the United States Maritime Administration’s fleet. It was one of the largest ships in the Ready Reserve Force (RRF), measuring 736 feet (224 meters) in length with a beam of 102 feet (31 meters). The ship’s primary capacity was to carry 364,000 barrels of oil (approximately 57,900 cubic meters), making it a significant asset for logistical operations. In 1987, the Mount Washington was transferred from commercial service to the Maritime Administration and became part of the RRF as one of 13 "Common User Tankers." It was maintained in a Ready Standby (ROS-40) status at Suisun Bay, meaning it could have been deployed within 40 days if activated. The vessel was equipped to support the Offshore Petroleum Discharge System (OPDS), a Navy-designed system used to deliver refined petroleum directly to shorelines during military operations. The OPDS system aboard the Mount Washington enabled the transfer of approximately 1.2 million gallons of petroleum per day from a moored tanker to shore facilities, with the tanker positioned about four miles from the coast. The ship’s crew consisted of civilian mariners, and maintenance, activation, and operation duties were handled by private contractors under MARAD oversight. The Mount Washington’s role was critical in supporting U.S. military logistics, particularly in delivering vital fuel supplies during emergencies or military campaigns. It was part of a broader strategic reserve, periodically tested through no-notice activations and routine exercises. The vessel was decommissioned and removed from the reserve fleet on November 18, 2013, and was subsequently sent to Brownsville, Texas, for scrapping. Its service exemplifies the vital logistical backbone provided by the Ready Reserve Force, supporting national defense and maritime readiness.
