Deep Space 3

Deep Space 3
Deep Space 3 was a Federation Starfleet starbase space station located near a Black Cluster. Deep Space 3 was commanded by Admiral Marcus Holt in the late 24th century. The station hosted the palio of 2370, where the Ferengi were accused of trying to bribe the Breen pilot into throwing the race. In 2370, the USS Hera, commanded by Captain Silva La Forge, left Deep Space 3 on a courier mission and disappeared shortly after. (TNG: "Interface"). Deep Space 3 is mentioned in Max Grodénchik's, Rom's Song, as the station where Odo moves to.

Being located in the Black Cluster, Deep Space Three is on the far reaches of Federation Space. Up until 2383, the nearest known Alpha Quadrant Power was the Breen. The Station was attacked by an unknown species, who were later identified by the USS Montana-A as the T'raQan Union. During the initial attack, DS3 was almost destroyed, and lost over 7,000 lives. The Montana and the attacking Vessels engaged in Combat, with all ships taking heavy damage, and suffering heavy casualties.

The repairs to Deep Space Three were conducted by the Starfleet Corps of Engineers, and was done alongside the repairs to the Montana.
