The Klingon Bird-of-Prey commanded by the ambitious Captain Klaa, who pursued the Enterprise-A to Nimbus III and beyond the Great Barrier in 2287 hoping to defeat James Kirk.
Klaa's Bird-of-Prey is the Klingon ship in Star Trek V: The Final Frontier. Its young captain, Klaa, is first seen blasting the old Earth probe Pioneer 10 for target practice and complaining that it does not fight back.
Sent to Nimbus III when hostages are taken there, Klaa sees a chance to make his name by beating Kirk. He and his first officer, Vixis, track the Enterprise-A through the Great Barrier to the planet Sha Ka Ree.
Spock persuades the freed Klingon hostage General Korrd, who outranks Klaa, to take over the ship. Its disruptor, fired by Spock, destroys the entity threatening Kirk, who is then beamed aboard. Klaa apologises for his unauthorised attack.
