The D'Kyr-class was a type of Vulcan Confederacy starship, a combat cruiser in Vulcan High Command service in the 22nd century. The D'Kyr vessels eventually served on the side of the Coalition of Planets allies during the Earth-Romulan War. (ENT episodes: "Future Tense", "Cease Fire"; ENT novel: Beneath the Raptor's Wing)
History
Edit
In the year 2154, a number of D'Kyr-class vessels were involved in the Battle of Andoria as part of Administrator V'Las' plans to invade Andoria. Several of these vessels also attacked the Earth starship Enterprise when they intervened in the conflict. (ENT episode: "Kir'Shara")
Later that year, a number of these vessels were assigned to the joint Andorian-Earth-Tellarite-Vulcan fleet that had combined to form a sensor grid that was to track down a Romulan drone ship which had attempted to create a rift between the different planets. (ENT episode: "United")
In 2155, two D'Kyr-class starships were captured near Alpha Centauri by the Romulans using the arrenhe'hwiua telecapture system. These two ships were used by the Romulans to wipe out a Human convoy and were then destroyed by Vulcan warships. (ENT novel: Beneath the Raptor's Wing)
Upgraded D'kyr class in the 25th century
D'Kyr-class science vessels were still in continual use following the 22nd century though the Vulcans had made upgrades to the technology used by these vessels. While initially used as combat cruisers by the Vulcan High Command, later iterations were used strictly for planetary defense, scientific exploration as well as rescue missions. Eventually, the design was shared with Starfleet allowing the Federation to build these vessels. (ST video game: Star Trek Online)
Kelvin timelineEdit
Following the destruction of the USS Enterprise at Altamid, Spock requested that Elder T'Pah dispatch one of these to assist the USS Endeavour. (TOS - Boldly Go comic: "Issue 2")
Mirror universeEdit
In the mirror universe, D'Kyr-class vessels were amongst the type of ships utilized by Vulcan rebels against the Terran Empire in the mid-22nd century. In early 2155, a number of D'Kyr's were among those who attacked the ISS Avenger. (ENT episode: "In a Mirror, Darkly, Part II")
SpecificationsEdit
Class variationsEdit
The hull of the D'Kyr-class science vessel did not allow its commanding officer to choose from different designs of livery, but the base type could be modified further. The base type was designated "Type 1". (STO - "The Klingon War" mission: "Welcome to Earth Spacedock")
Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion. (STO missions: "Coliseum", "Cold Storage", "Boldly They Rode")
