USS Moncrief (NCC-3800)

USS Moncrief (NCC-3800) was the lead ship and prototype for the transport/tugs on active duty in Starfleet during at least the 23rd century. The class was authorized in July, 2266, but refits and new-build vessels in this configuration would have to wait until the 2270s. ((, 2006 revision)

In the late 2260s, the Moncrief would undergo successful trials but refits of the ships would not be authorized until linear warp drive was tested on vessels such as the Decatur, Intrepid and Enterprise. (, 2006 revision)
