In the event of an attack on Deep Space 9 by hostile forces such as the Dominion, starships stationed at Starbase 257 were to travel there to assist the USS Defiant and the Danube-class runabouts in protecting the space station. (DS9 reference: Star Trek: Deep Space Nine Technical Manual)

Location

Starbase 257 was located in relatively close proximity to Deep Space 9 in the B'hava'el star system. (DS9 episode: "Valiant")
