A Federation starbase where the Enterprise-D stopped in 2365 for engineering consultations, and where civilian adviser Kyle Riker boarded to brief his estranged son on a possible command.
Starbase Montgomery is a Starfleet facility featured in the second-season Next Generation episode The Icarus Factor.
In 2365 the Enterprise-D diverts there so that the base's engineers can look into minor readout anomalies in the ship's systems. While in orbit Picard learns that Commander Riker has been offered command of the USS Aries, a small ship bound for a distant exploration mission, and that a civilian strategist will come aboard from the starbase to brief him.
The adviser turns out to be Kyle Riker, the first officer's father, whom he has not spoken to for fifteen years. Their difficult reunion, settled in the end by a bout of anbo-jyutsu, takes place while the ship remains at Montgomery. Riker finally decides to stay on the Enterprise.
