2. Vor'Cha-class
Key Appearances: Reunion, The Way of the Warrior, Sons of Mogh, What You Leave Behind, Redemption One of the most impressive members of the Klingon fleet, the Vor'Cha-class was the flagship of the Klingon military for a number of years until the beginning of the Dominion War. The Vor'Cha-class contained an extremely impressive armament and was also very maneuverable for its size. The Vor'Cha-class featured prominently in Deep Space Nine but also appeared in many episodes of the Next Generation, particularly during the Klingon Civil War. The Vor'Cha-class has to be one of the most intimidating looking spaceships ever put on screen and its appearance its perfectly indicative of the type of people in charge of their operation. To sum it all up, the Vor'Cha-class is simply the most awesome ship in Star Trek that is not operated by the Federation.
