The Second Battleship Division is a unit within the Lost Fleet. At the time of the flight from the Syndic home system, the Second Battleship Division consisted of the battleships Gallant, Indomitable, Glorious, and Magnificent.

The Second Battleship Division was something of a rarity in that none of its vessels were lost during the long trek back to Alliance space. As such, the Division, in its original form, was able to take part in Fleet Admiral Geary's return to Syndic space, and the ensuing conflict with the Enigma Race.
