Star Trek Expanded Universe

Deep Space 10 was a Federation Starbase constructed between 2380 and 2382. It was the largest in the Galaxy. Manned by a staff bordering 125,000 including Marines, and hosting as many 800,000 inhabitants at one time, it had an incredible capability of hosting personnel, including as many as 1.25 million. DS10 hosted sections of the 14th Fleet, and 24th Fleet. (Star Trek: Generation Fleet)


The need for the starbase was realized in 2378 as contact with New Talaxia in the Delta Quadrant via the MIDAS Array found increasing tensions in the area by the Malon. In 2379, the USS Expedition was sent to the Delta Quadrant on the behest of Ambassador Neelix in hopes of defusing the situation with the Malon. From the outset plans went smoothly, but threats by past mining proprietor Nocono led Captain Vanessa Yates in requesting the Federation starbase be located at the colony.

In 2380, the Expedition would return with a convoy of ships that began construction of the new Starbase. The appearance of the Federation in the Delta Quadrant was not well received. After construction, DS10 faced destruction several times from several factions, with the Malon, and the Hirogen as their strongest opponents.

The Hirogen[]

In 2384, the Hirogen found themselves for the first time outnumbered when they first encountered the Starbase. When the Expedition surrendered to them, they were escorted to the starbase when it was apparent that a peaceful solution would benefit them in regards to Starfleet. Yet only a year later would the Hirogen return, this time to destroy the starbase with an armada of 200 Hunter ships. The Expedition lead a diversionary assault while land mines were laid to prevent any further attempts on the Starbase.

Malon Attack[]

By 2386, a coalition of Malon waste management owners and their crews that were forced out of business due to their inability to conform to new waste management protocols amassed an armada with the intent of destroying Deep Space 10. Using a ship containing lethal thalaron radiation, they used a dummy fleet of ships to detonate the minefield, and make a clear path to the starbase. Sacrificing her ship, Captain Vanessa Lucifel rammed the Expedition into the Thalaron-loaded ship, effectively destroying the majority of the remaining fleet and sending the Malon fleeing. The resulting Thalaron explosion created a natural barrier from any other future attacks.

New Talaxia colony[]

The colony below was still inhabited, but the search continued for a New Home for the Talaxians. With Thalaron Radiation in the area, talks of giving the asteroid back to the mining consortium were in progress. A class M planet had been found some 3.2 light years away, but Ambassador Neelix, felt the importance of Deep Space 10, remained there with his family.
