Colonial One
the presidential ship
Colonial One was a civilian passenger liner that became the official residence and workplace of the President of the United Colonies of Kobol after the Fall of the Twelve Colonies. Formerly Colonial Heavy 798, it served as the seat of the surviving government throughout the search for Earth.
Colonial One, formerly known as Colonial Heavy 798, was a civilian starliner chartered by the Colonial government. Following the Fall of the Twelve Colonies, it became the official residence and workplace of the President of the United Colonies of Kobol, serving as the seat of the surviving civilian government alongside Galactica's military command throughout the fleet's search for Earth. (Battlestar Galactica (2003 miniseries))
The Fall and the birth of a presidency#
In the hours before the Fall, Colonial Heavy 798 flew from Caprica to Galactica, carrying Secretary of Education Laura Roslin, her staff and members of the press to the battlestar's decommissioning. The Cylon attack began about three hours out from Caprica on the return trip, with Lee Adama escorting the liner in his father's old Viper. When a Raider attacked, Lee decoyed the missile aimed at the ship and shot it down, and the damaged Viper was taken aboard. (Battlestar Galactica (2003 miniseries))
As the highest-ranking official aboard, Roslin took charge of the ship and set it up for the long haul. When the Case Orange broadcast showed that the line of succession had collapsed, she was sworn in as President, and the ship was rechristened Colonial One. It then gathered other civilian ships stranded around Caprica into a refugee convoy. When the Cylons found the convoy, Roslin ordered every FTL-capable ship to jump, leaving the sublight ships behind. The survivors later met Galactica at Ragnar and left the system altogether in search of Earth. (Battlestar Galactica (2003 miniseries))
The seat of government in exile#
Though Galactica coordinated military strategy, Colonial One kept the civilian government physically separate from the military, with its own Presidential Security Service. That separation was tested when a Galactica Marine unit boarded the ship to arrest Roslin after William Adama judged her orders to Lieutenant Kara "Starbuck" Thrace a threat to fleet security. Years later, during the Battle of the Ionian Nebula, the ship was nearly destroyed by a Cylon missile that Diana Seelix intercepted just in time. (Battlestar Galactica, "Kobol's Last Gleaming, Part II"; Battlestar Galactica, "He That Believeth in Me")
After the discovery and colonization of New Caprica, Colonial One landed on the surface and became the residence and office of President Gaius Baltar. During the following year's Cylon occupation, a Cylon committee joined Baltar aboard and ran the real government from it. In the liberation and evacuation that followed, Roslin and a small armed group boarded the deserted ship and flew it off the planet, the last human ship to leave New Caprica. (Battlestar Galactica, "Occupation"; Battlestar Galactica, "Exodus, Part II")
Final service and fate#
The Quorum of Twelve, which had once met aboard Cloud 9, also met aboard Colonial One. Those meetings ended during the mutiny on Galactica, when Vice President Tom Zarek had a mutinous Marine unit massacre the delegates after they refused to legitimize the uprising. Roslin moved her government to Galactica after that. Colonial One was ultimately destroyed after the fleet reached the planet rechristened Earth, when Samuel Anders flew it and the rest of the fleet into the sun by remote control. (Battlestar Galactica, "Blood on the Scales"; Battlestar Galactica, "Deadlock"; Battlestar Galactica, "Daybreak, Part II")
