The Delta Aquilae Decommissioned Ship And Salvage Facility is administered by Starfleet and is located in the Delta Aquilae area of the Alpha Quadrant.
The mission of the Delta Aquilae Facility is to store decommissioned starships, recover destroyed Starfleet vessels and salvage all useable components from those vessels for reuse. Delta Aquilae has many nicknames such as 'the Boneyard', 'the Junkyard', and 'the Graveyard' to name a few.
The Delta Aquilae facility is the largest such facility in the Federation. It was built by Starfleet Corp of Engineers in 2230 as a primary fleet salvage yard. Originally built to store only destroyed Starfleet vessels and dismantle them for recycling, it was later expanded to also act as a storage facility for 'retired' or 'decommissioned' starships. It became the official home to the 'Mothball Fleet'.
Delta Aquilae Decommissioned Ship and Salvage Yard was established in 2230 as a Starfleet salvage yard and was designated Delta Aquilae Fleet Salvage Yard. It was immediately put to work dismantling obsolete Starfleet vessels of all types. 35 vessels were dismantled in the first six months of the facility's operation and for it's first fifteen years Delta Aquilae would average about 75 to 85 ships salvaged and dismantled a year. This number stayed constant as older ships were being pulled out of service and replaced by newer designs.
During the Klingon War of 2245 starship losses climbed and a 'Salvage Unit' was added to the facility in order to recover destroyed ships whenever possible and tow them to the station. A Bio-Recovery Unit was permanently attached to the facility to handle the remains of dead Starfleet personnel. Mortuary and DNA labs were added to the station.
Following the war, Delta Aquilae was physically expanded as was it's mission. Starfleet realized the need for a 'Fleet Reserve' to be made up of decommissioned ships that could be put back into service at a moments notice. The losses suffered during the war had been moderate, but the fact that Starfleet did not have a ready reserve shook the admiral and moved them to action. By the 2250's Delta Aquilae had a 'mothball fleet' of 45 decommissioned ships in storage.
By the time of the Klingon War of 2256/2257 Delta Aquilae had an active fleet of 27 tugs, 45 long range shuttle craft, 12 minesweepers, and a hospital ship. It was commanded by a two star rear admiral and had a staff of 1700. By the end of the war all of the 'mothballed' starships that were stored there had been sent to the fleet to replace losses. During the conflict 12 tugs and 4 minesweepers were lost to enemy action while on recovery duty in the battle zone. None the less, over 96 Starfleet vessels were recovered by the valiant crews of the Delta Aquilae tugs.
After the war ended, the surviving tugs went out and recovered hundreds of destroyed Federation and Klingon ships. So many were recovered that Starfleet authorized the construction of two more facilities and expanded Delta Aquilae. During this time the shipyard began to temporarily repair battle damaged ships as well as dismantling the destroyed ships they recovered.
The staff was increased to 2200 during this time and remained at that number throughout the rest of the 23rd century. The base was expanded and refurbished in the 2260's and 2280's as more older starship were being retired. By the 2310's Delta Aquilae had a 'mothball' fleet numbering 150 ships when Starfleet Command gave the order to cut that number to 40. Many Constitution Class vessels were destroyed at this time because the newer Constellation Class were replacing the venerable veterans.
Delta Aquilae and her sister installations continued with their mission well into the 2340's and '50's. By the 2360's the facilities staffs had been increased to 3000 and by 2365 all three installations were under the command of one four star Starfleet admiral. The service fleet was expanded to 35 tugs, 15 minesweepers, and 4 patrol destroyers were added in 2364. In 2266 the authorized number of 'mothballed' ships was increased to 120 per installation. The facility saw action during the Cardassian War, the Borg invasion, and especially the Dominion War when it won distinction for the 'mothball' fleet's return to action. During this conflict the bases' commanding admiral authorized 4 mothballed cruisers be returned to service to augment the facility's defense.
By the 2380's Delta Aquilae was expanded again and it's aging infrastructure refurbished. She and her sisters continue in their mission well into the 2400's and beyond.
