Shenlong was constructed under the supervision of Admiral Alexis Osman of the Alpha Centauri Space Research Council, and Commodore W. M. Jefferies of the Starfleet Corps of Engineers as part of a new wave of Columbia-class starships. With Shenlong and Buran active by July 8, 2165, USS Endeavour was not the sole Columbia-class ship in service anymore. (ENT - Rise of the Federation novel: Live by the Code)
