The Colonial Ministry of Defense was the branch of the Colonial Government responsible for administering its military forces. As with the Caprican Ministry of Defense of 42YR, it successor was headquartered on Caprica, and overseen by various groups including the Admiralty, of which Admirals Peter Corman and Nagala were a part circa 6 BCH (94YR) to 0 BCH (2000BYR) respectfully.

Its scope of operations included the defense of the Twelve Colonies from the Cylon threat, should they ever decide to return; and it conducted research and development into technologies that could improve the success in those missions.


An Armistice Officer from the Ministry was sent every year following the Cimtar Peace Accord (colloquially known as the Armistice) to the Armistice Station to maintain diplomatic relations with the Cylons, beginning 40 BCH (60YR) up until the eve of the Fall of the Twelve Colonies, becoming the first known casualty connected to that event (TRS: "Miniseries, Night 1").

Kendra Shaw was reassigned from a Ministry assignment to Pegasus on the eve of the Fall (TRS: "Razor").

Prior to the Fall circa, Commander William Adama of Valkyrie was assigned to clandestinely probe behind the Armistice Line circa 6 BCH (94YR). Its failure results in the reassignment of key command personnel, including Valkyrie executive officer Saul Tigh to Galactica (TRS: "Hero").

The Fall

Dr. Gaius Baltar was a consultant for the Ministry and worked on the development of the Command Navigation Program, which became an integral part of much of the Colonial Fleet's systems. One of Baltar's lovers, a contractor at the Ministry, assisted him with the CNP's programming circa 2 BCH (98YR).

On the day of the Fall of the Twelve Colonies, this woman reveals to Baltar that she is a Cylon agent, sixth out of 12 humanoid models, and that with the access she gained through Baltar, she was able to penetrate extremely sensitive assets such as the Colonial Defense Mainframe. In the course of fixing over half of Baltar's CNP programming algorithms, she secretly added backdoors into the program that would cripple the bulk of the Colonial Fleet and expose the Twelve Colonies to Cylon attack.

During the attack, the captain of Colonial Heavy 798 established contact with Jack at the Ministry, whom Laura Roslin was barely able to debrief prior to 798's detection by the Cylons (TRS: "Miniseries").

Dr. Amarak also worked at the Ministry and was a colleague of Baltar. He is presumably killed when Galactica's CAP destroys Olympic Carrier, if not earlier by Cylon hands.

When a copy of Number Six appears on Galactica under the alias of Shelly Godfrey, she pretends to be a systems analyst at the Ministry and the lover of Dr. Amarak (TRS: "Six Degrees of Separation").

Kendra Shaw's Ministry of Defense patch (TRS: "Razor").


  • In the Miniseries, Roslin refers to a Ministry of Civil Defense. It is unknown if this is a synonym for the Ministry of Defense or a separate ministry akin to the American Department of Homeland Security.
  • The patch's lower text, "Kobol HQ," is likely a continuity error based on early drafts of the Miniseries script, where Kobol itself was originally the single homeworld of the Twelve Colonies.
