The single-seat Viper Mk. II, suitable for flight both in planetary atmosphere and deep space, is reputed to be the most famous space superiority fighter used by the Colonial Forces. The first examples, specially designed for use on Battlestars, went into service shortly before the start of the first Cylon War. The Mk. II saw exemplary service during the first Cylon War which earned it special recognition throughout the twelve colonies. It is regarded as one of the reasons why the Colonials were not beaten by the Cylons, which explains its great fame. The fighter, which is about 8.40 m long, is flown by one pilot, has two kinetic energy weapons and external stations for rockets, munitions carriers and other equipment under the wings.
