D7 class

The D7 class battlecruiser was a type of warship starship 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 and specifications[]

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 in the 2250s decade. (Star Trek Adventures RPG module: Core Rulebook)

Similar designs had been in service since as early as the year 2151. (ENT episode: "Unexpected")

D7ClassProposal — The proposed D7 design presented to the High Council in 2257.

By the mid 23rd century the class had become the mainstay of the fleet. In the 2250s some D7s were used as prison ships. (DSC episode: "Choose Your Pain")

Following the Federation-Klingon War of 2256-2257 a new D7 variant was designed. Instead of bearing the banner of any one Klingon House, the new cruisers were intended to bear the mark of the unified Klingon Empire, and become the mainstay of the fleet following the war. (DSC episode: "Point of Light")

D7-2257 — One of the first new D7s created after the war.

After a red burst was observed over Boreth, Chancellor L'Rell traveled to that world on one of the first new D7s of that variant to meet with Captain Christopher Pike on the USS Discovery. (DSC episode: "Through the Valley of Shadows")

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: Starfleet Intelligence Manual)

A variant of this cruiser was the D7-A, which saw use as early as 2269. Another significant class variant was the D7-M or K't'inga-class. (FASA RPG module: 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)

Variants[]

The D7 class name describes any number of variants of the class, which included many individually named and numbered series.

Akif-class (battlecruiser)
Klolode-class (D7-D5)
K't'agga-class ("Painbringer", D7A cruiser)
K't'kara-class ("Bringer of Destiny", D7C cruiser)
K't'alla-class ("Truthbringer", D7G cruiser)
K't'inga-class ("Bringer of Destruction", D7M cruiser/battlecruiser)
K't'rika-class ("Bringer of Agony", D7R cruiser)
K't'mara-class ("Bringer of Justice", D7S cruiser)
Koloth-class (frigate)

The Romulan-owned D7s were referred to as Stormbird-class vessels, and that class name seems to refer to multiple types listed above, most notably the Akif and K't'inga-classes.
