8) U.S.S. Defiant NX-74205, Star Trek: Deep Space Nine (“The Search”)
While all of their ships have been armed, Starfleet’s mission has always been one of peace,” and the concept of a starship dedicated to combat doesn’t exactly gel with that. It takes Commander Sisko to see the Defiant’s true potential.
Unlike the smooth curves of usual starships of Starfleet vessel, The Defiant is rather unusual and not pretty
First off, in addition to her standard phaser arrays, the Defiant was armed with four phaser cannons. Except the standard “beam-like” phaser; the phaser cannon behaved more like a gun and was incredibly devastating when fired in bursts, all four cannons blazing. Additionally, the Defiant was also packing six Quantum Torpedo launchers (four forward firing, two rear). It could discharge her shield system like a weapon a-la the Macross Cannon, and in a pinch could fill her nose with torpedoes and launch it like a big-ass missile. To add insult to injury, the Defiant was also the first and only Federation starship packing a Romulan Cloaking Device, rendering this little monster invisible, silent and deadly.
7) Prototype Klingon Bird of Prey, Star Trek VI: The Undiscovered Country
For long Starfleet or for that matter, everyone had to live with a simple design flaw in the cloaking device: It draws so much power that a cloaked ship CANNOT fire while cloaked.
In Star Trek VI: The Undiscovered Country however, a cast of conspirators including the members of the Federation, Klingon and Romulan governments, develop and deploy a Klingon Bird of Prey that has the ability to fire while cloaked. This raises the stakes in the game! In the climactic battle of Star Trek VI, this very special Bird of Prey (considered a light vessel, carrying a crew of 12-36, with armaments considered 1/10 as powerful as the Consitution Class USS Enterprise) is able to take on and heavily damage both the USS Enterprise and the USS Excelsior. It’s only due to the combined efforts of the two Federation starships, Captain Spock, and Doctor McCoy that the Bird of Prey was destroyed. Thanks to the shortsightedness of the conspiracy, they only built one, And even as far as a century later, the Star Trek universe does not have ships that fire while cloaked… or do they?
