Command Navigation Program

Developed by Dr. Gaius Baltar, the Command Navigation Program (CNP) was a program utilized by the Colonial military forces and some civilian spaceships in the Twelve Colonies.Template:Ref Installed in the central computers of Vipers and Raptors and in the navigation computers of almost all battlestars, the CNP was more than two years in the making.

Unbeknownst to Baltar, a lover and cowriter of the CNP turned out to be a version of the Cylon agent known as Number Six. She programmed backdoors into the program so that the Cylon attack force could break through the Colonial firewalls. Vipers with the CNP that received a command from attacking Cylon ships would be shut down "as if a switch were flipped." Dualla described reports of "system failures" throughout the Fleet and how at least one battlestar lost power when the attack began, which indicate the Cylons used the CNP to damage and, in at least one case, disable capital ships as well (Miniseries).

The CNP was distributed via the Colonial Defense Mainframe,^{[citation needed]} where Six had unrestricted access on Baltar's authorization.

The CNP was received by battlestar Galactica, but the program was never loaded into the primary memory of the ship's navigation computer, although her last squadron of Mark VII Vipers received the upgrade. As a result, the squadron was massacred by two Raiders on their way back to Caprica.

Lieutenant Felix Gaeta had the program code purged from the mainframe on Baltar's suggestion, and the program was also retrograded on the flight systems of surviving Mark VII Vipers and Raptors (Miniseries).
