The Peregrine-class are small starships used by Starfleet to act as couriers and fighters. By the late 2360's and early 2370's these craft were used by the Maquis as a modified, lightly armed interceptor for raids against the Cardassians in the Demilitarized Zone. Starfleet also began to use these small fighters against the Dominion because of its smaller size they were more maneuverable and could attack enemy ships at close range making it difficult for their sensors to lock-on with phasers and being to close to fire torpedoes.

Chakotay's raider was given the name Liberty in the Voyager novel 'Pathways', the Star Trek Fact Files however give it's name as Zola.
