The D'Kyr type was a type of Vulcan starship operated by the High Command during the mid-22nd century. Some of these vessels were given the designation of combat cruiser in the 2150s. In 2154, a number of these starships were present at the Battle of Andoria, carrying out the ill-wishes of then - Administrator V'Las, which included not only attempting to invade Andoria - but almost going to war with Earth by trying to destroy Enterprise NX-01. Later that year, several of these combat cruisers were incorporated into an Andorian-Earth-Tellarite-Vulcan fleet, consisting of 128 ships, combined to create a sensor grid formed to detect a Romulan marauder that threatened to destabilize the entire region.
