The Viper is the main stay of the Galactica fleet. Without the Viper, the fleet is dead. It is equivalent to the Cylon Raider, the craft used by the Cylons. Unlike the fighter crafts used by the Cylon, the Viper didn't change their look when the series was rebooted. The fighter craft were both single seat jets. Should transporting be required, the Colonials would use the Colonial Raptor. Raptors were able to carry more people and goods and were able to travel further distances than these crafts.
