Duras' Bird-of-Prey was a 22nd century Klingon Bird-of-Prey commanded by Duras, son of Toral following his demotion as commander of the IKS Bortas. In mid-2153, Duras was given command of this Bird-of-Prey and assigned to capture Jonathan Archer, the captain of Enterprise NX-01. Although his ship outgunned Enterprise during its first attack as the latter ship approached the Sol system, it proved no match for a squadron of three Starfleet vessels, including the Intrepid.
