Starbase 93
Devron Fleet Yards (DFY) is a maintenance and repair facility in the Beta Quadrant on the border of Federation space adjacent to the old Romulan Neutral Zone. Rather than constructing new starships, DFY was originally built to support the massive evacuation effort of the Romulan homeworld in the early 2380s. The yard continues to service starships engaging in humanitarian support and border patrol missions in the area, especially when they need more extensive repairs than nearby border outposts can provide. Though not a starbase, it now serves as headquarters to the Fourth Fleet's Task Force 93, which formerly had jurisdiction over the entire Romulan Border but now handles humanitarian missions across Federation space.
While relations between the Federation and the splintered Romulan factions have remained cool to cordial (depending on the faction), the area near DFY is unstable on both sides of the border, necessitating missions launched from DFY on runabouts and Task Force 93's starships to help stabilize the region.
Facilities
Compared to other yards, DFY is relatively small: comprising an Unity-class station at its core and several drydock frames to accommodate more extensive repairs and refits than the station itself is able to handle.
DFY Headquarters (Unity-class station)
Unity-class stations are powerful defensive installations, capable of serving multiple starships at the same time. Unlike spacedocks, they lack a large internal hanger, so ships larger than escorts must dock at external ports. These ports can handle both resupply and provide external power generation while starships are being serviced. The station houses recreational facilities, residences, shops, and cafes with enough capacity to handle both the permanent crew complement of the starbase and the crews of starships undergoing repair or refit.
Drydocks
While the headquarters station is capable of handling repairs of moderate complexity on its own, more extensive repairs require the use of one of the yard's drydocks. These support frames provide starships with external power, life support, and radiation shielding, in addition to storage area for repair and refit supplies. Presently, DFY has two large articulated drydocks for explorers, four drydocks sized for heavy cruisers, and another four small drydocks for vessels up to the size of the Intrepid-class. Crews travel to their work sites via transporter from the main station, as there are no accommodations on drydocks.
