Defender class

The Defender-class was a type of starship operated by the Federation Starfleet as a bomber in the 2250s of the alternate reality created by the temporal displacement of the Narada.

Specifications
The class featured a small saucer section connected at the rear to an elongated secondary hull. On either side of the engineering hull were pylons connecting to pairs of warp nacelles, giving the class four nacelles in total. The Defender-class was designated a bomber, and was armed with explosive charges which it could deploy in its wake. The class was faster than its Starfleet contemporaries, allowing it to make fast runs into enemy controlled areas to deploy it's weaponry.

Like its contemporaries, the Arbiter-class, Constitution-class, Guardian-class, and Interceptor-class, the Defender-class could, in addition to its standard systems, be armed with quantum torpedoes, and the ability to temporal shift. Also in common with other classes, the Defender-class had at least one military shuttle, which could be used as an escape pod.

History
In the 2250s members of the Defender-class vessels were part of the Starfleet force that battled starships of the Romulan Star Empire.
