The Colonial Viper is the primary space superiority fighter and attack craft deployed by the Colonial military. Capable of both atmospheric and long-range spacial flight, the Viper is a single-pilot craft with two-forward mounted laser-torpedo guns as standard.
In the 18 yahrens since the exodus of Man from the Twelve Colonies of Man, Galactica's numbers varied. In 7342, Galactica carried a compliment of 75 Vipers, whose numbers depleted to less than forty around 7352. In the few yahrens that followed this decline, the Fleet discovers a planet rich in the material resources to not only repair (and retrofit) ships, but also the creation of two new Viper classes to restore Galactica's depleted ranks (RH: Armageddon).
- Azure-class Viper: A successor to the Viper seen in the Original Series, and built on Hephaestus. This version is a rebuild of the earlier model of Viper available to Galactica, featuring a new pulsar system with efficient tylium usage, thereby reducing solium leads. More than forty were constructed before resources were allocated to its successor, the Scarlet-class (RH: Armageddon).
- Scarlet-class Viper: A successor to the Azure-class, Galactica began building these class of Vipers 18 yahren after "The Hand of God", circa 7360. The first one is given to Lieutenant Commander Apollo, with a second one slated for Captain Starbuck, who stuck to his older Viper (RH: Armageddon).
