Corrected entry: During the fleet battle Sisko says, "Evasive maneuvers, Pattern Omega. We're going through." After he says this, there is a flash of light on the bridge. During the flash, if you look closely, there is a ship diagram in the background behind Sisko on the left side of the screen. This is a diagram of an Excelsior-class ship, and the Defiant is NOT an Excelsior-class starship.
