Caprica Prequel (2010)
An aircraft also called a Viper is briefly mentioned in the Caprica episode "Ghosts in the Machine". In the episode it is a fighter jet in a virtual reality game, so it may not even be a "real" aircraft in the fictional Caprican military. If it is a fighter in the Caprican military, it is possible that the Colonial Viper was named in honour of this craft (i.e., it is not part of the previously understood Viper lineage) in the same way the World War II Hawker Typhoon has also lent its name to the modern Eurofighter Typhoon.
