Starbase 3141 Romeo

Starbase 3141 Romeo was a Federation space station, a variant starbase in Starbase service in the 23rd century. In the 2270s decade, Starbase 3141 Romeo was located near a gas giant at the Federation border. A separate drydock had been built inside a nearby asteroid. 

Service history
In the year 2270, the station's commanding officer was a male Human. Commander Montgomery Scott was aboard the asteroid drydock when a hostile fleet attacked the Federation border system. A squadron of Alpha Quadrant Alliance starships from the year 2410 arrived in the system, disguised as contemporary Federation vessels. The Allies defended the station and faced off against a doomsday machine the Na'kuhl had delivered to the hostile attackers. Scott led the drydock's engineers to produce warp cores, including one meant for a dreadnought, to stop the doomsday machine.

Slowing the doomsday machine by dropping Scotty's warp cores in its path and holding off the hostiles, provided the engineers with the time to ready the dreadnought's warp core. The Allies saved the starbase by halting the doomsday machine with the largest warp core, and the hostiles retreated from the Federation border, foiling the Na'kuhl's plan to upend the timeline.
