The Maumee class was a class of four United States Navyfleet oilersin service from the mid-1950s until the mid-1980s. It was the first class of United StatesNaval Ships. The Maumee class ships were the first of the Navy's new "supertankers", significantly larger than previously classes. They also were the first U.S. Navy ships specifically designed and launched with an intention that they be operated in a non-commissioned status by the Military Sea Transportation Service, later the Military Sealift Command, with civilian crews working under contract. They thus became the first United States Naval Ships, and the first to be given the designation "USNS" instead of "USS". The "T" appended to the beginning of their hull numbers indicated civilian manning, a convention still in use today. When the lead unit, USNSMaumee, entered service in December 1956, she was the first USNS ship in history. The ships were not designed for underway replenishment. Rather they were intended to transport bulk petroleum products, such as fuel oil, gasoline, and aviation fuel, to Americanmilitary forces overseas. At some time after the loss of USNS Potomac in 1961, the three survivors were reclassified as transport oilers, and were redesignated as such by having an additional "T" appended to their hull code.
Naming
The class was named for its lead unit, Maumee. All four ships were named after American rivers with Native American names, a traditional convention for U.S. Navy oilers.
Operations
The ships spent their careers in non-commissioned service in the Military Sea Transport Service, later the Military Sealift Command, operating with civilian crews, from the mid-1950s. After the loss of Potomac, the survivors served until probably the mid-1980s.
Ships
USNS ''Maumee'' (T-AO-149)
transported petroleum primarily in the Pacific, operating in this role between mid-December 1956 and probably the mid-1980s. She eventually was reclassified as a "transport oiler" and redesignated T-AOT-149.
USNS ''Potomac'' (T-AO-150)
transported petroleum from 1957 until 1961, when she was destroyed pierside by a fire and explosions. Although her forward half was a total loss, her after half was salvaged and used in the construction of fleet oiler USNS Potomac.
USNS ''Shoshone'' (T-AO-151)
transported petroleum worldwide between mid-December 1956 and probably the late 1980s. Eventually reclassified as a "transport oiler" and redesignated T-AOT-151.
USNS ''Yukon'' (T-AO-152)
transported petroleum worldwide between mid-December 1956 and probably the late 1980s. Eventually reclassified as a "transport oiler" and redesignated T-AOT-152.
