Galactica (BS 75) is a veteran battlestar and the last of her kind still in service with the Colonial Fleet at the time of the destruction of the Twelve Colonies. Built during the early days of the Cylon War, she remains the only military vessel without integrated computer networks. Without networked computers, Galactica never upgrades to the new integrated defense system software developed by Dr. Gaius Baltar and his team. Because of this and other factors, she becomes one of only two known battlestars (the other being Pegasus) to survive the renewed Cylon attack on the Twelve Colonies. At the time of this attack, she was part of the 75th Battlestar Group (BSG-75).
