Description: The D7 class battlecruiser was a type of warship designed and built by the Klingon Empire during the mid 23rd century. Many also entered the service of the Romulan Star Empire following the formation of a Klingon-Romulan alliance in the 2260s. (TOS episodes: "Elaan of Troyius", "The Enterprise Incident", "Day of the Dove"; WizKids module: Attack Wing)

History

The D7-class was the next step in Klingon battlecruiser design, its form being a development of the earlier D4 class. The first prototypes entered service as early as 2151 (ENT episode: "Unexpected")

By the mid 23rd century the class had become the mainstay of the fleet. Following the formation of a Klingon-Romulan alliance in the 2260s, many D7s entered service in the Romulan Star Empire as Stormbird-class cruisers. (TOS episode: "The Enterprise Incident," FASA RPG module: The Romulans: Star Fleet Intelligence Manual).

A variant of this cruiser was the D7-A, which saw use as early as 2269. (FASA RPG: Star Trek IV Sourcebook Update).

A significant class variant was the D7-M or K't'inga-class. (FASA RPG: Star Trek IV Sourcebook Update).

In 2272, several D7-class ships were among the Klingon vessels assimilated by the Borg, who were manipulated by the rogue Vulcan scientist T'Uerell while she was allied with the Klingons. These assimilated Klingon ships engaged Starfleet in battle, during Admiral James T. Kirk's efforts to thwart T'Uerell's plans, and were destroyed. (ST video game: Legacy (game))
