Construction of the Sedgemoor Tann was completed on reference stardate 2/9608, in the latter part of the 2350s decade. This vessel was commissioned at one of the two shipyards that produced Paine-class vessels, either Deneva Shipyards or Gibraltar Shipyards. The Sedgemoor Tann was refit to new specifications on stardate 2/9806. (FASA RPG module: Star Trek: The Next Generation Officer's Manual)
