Expert opinions and little-known perspectives
The USNS American Explorer (T-AO-165) was a fascinating Cold War–era vessel, originally conceived as the world’s first nuclear-powered commercial tanker. Her keel was laid in July 1957 at Ingalls Shipbuilding in Pascagoula, Mississippi, and she was launched in April 1958. The nuclear concept was highly ambitious, intended to outpace earlier Maumee-class oilers by achieving higher speeds and carrying capacity. However, the nuclear propulsion plan was never fully realized due to funding concerns, congressional hesitation, and technical challenges—leaving the ship to be completed with a conventional steam turbine system. Even so, she emerged as one of the fastest tankers of her day, boasting 22,000 horsepower.
Once delivered to the Military Sea Transportation Service (MSTS) in October 1959, American Explorer served for nearly 25 years as a tanker supporting naval logistics along the Atlantic Coast. Her designation as AO-165 reflected her role as an oiler, and in September 1978 she was reclassified as AOT-165, a “transport oiler.” This new classification emphasized her mission of moving fuel between fixed ports, rather than replenishing ships at sea. In that role, she became a workhorse of Cold War naval supply chains, ensuring petroleum products were consistently available for U.S. bases and vessels.
Her later years saw a transition away from active operations. By June 1984, the American Explorer was transferred to the Maritime Administration’s Beaumont Reserve Fleet in Texas, where she remained laid up. Decades later, in July 2008, she was sold for scrap to Southern Scrap Metal Corporation of New Orleans. Her story might have ended quietly, but Hurricane Gustav in late August 2008 brought her back into the spotlight when she broke free from moorings, colliding with New Orleans’ Florida Avenue Bridge and damaging nearby infrastructure before being secured by the Coast Guard.
To summarize her service in timeline form:
1957–1958: Keel laid and launched at Ingalls Shipbuilding, Pascagoula.
1959: Delivered to MSTS with conventional propulsion.
1959–1978: Served as AO-165, hauling petroleum products along the Atlantic.
1978: Reclassified as AOT-165.
1984: Entered Beaumont Reserve Fleet.
2008: Sold for scrap; broke loose during Hurricane Gustav incident.
The USNS American Explorer represents both unrealized innovation and dependable utility. While she never became the pioneering nuclear tanker her designers envisioned, her speed and endurance made her a valuable logistics ship for decades. Her history illustrates the U.S. Navy’s experimental ambitions during the nuclear age, balanced by practical decisions that favored proven technologies. Even in her final years, the American Explorer left a mark on maritime history—reminding us how ships often outlive their original design intentions, adapting to the demands of each era.
