Deep Space 3 was a Federation space station that was in service with Starfleet in the late 24th century. In 2370, the commanding officer of this station was Vice Admiral Marcus Holt.

In that year, the station hosted the annual palio, wherein the Ferengi were accused of trying to bribe the Breen pilot into throwing the race.

Nine days before Holt contacted Captain Jean-Luc Picard, the Template:USS, commanded by Captain Silva La Forge, departed Deep Space 3 on a routine courier mission. For five days, the station was in contact with the starship. After the ship vanished without a trace, Holt recruited the Template:USS and the Template:USS for the task of finding the lost Hera. For seventy-two hours, the ships retraced the course of the Hera, without success. Holt planned on having the ships continue the search for another seventy-two hours; however, he did not think the additional time given to the ships would make a difference. (Template:TNG)
