6. Klingon Bird-of-Prey
Key Appearances: Star Trek III: the Search for Spock, Star Trek IV: The Voyage Home, Star Trek V: the Final Frontier, Star Trek VI: the Undiscovered Country, Call to Arms, Soldiers of the Empire A mainstay of the Klingon fleet for a century in different forms, the Bird-of-Prey might be the definitive non-starfleet vessel in Star Trek. While designed more as a support vessel than a flagship, the Bird-of-Prey was more than capable of holding its own with all but the most powerful ships in the quadrant. Bird's-of-Prey were equipped with a cloaking device as well as the most advanced weapons technology in the Klingon Empire. The Bird-of-Prey is one of the most prominently featured starships in the Trek canon, appearing in twelve episodes of Next Generation, twenty-nine episodes of Deep Space Nine, two episodes of both Voyager and Enterprise as well as five of the films. The ships classic look and impressive capabilities make it one of Star Trek's defining vessels.
