The K't'inga-class battle cruiser is one of the oldest, most easily recognizable designs in the history of both the Alpha and Beta Quadrants. The general design of the Klingon battle cruiser has remained the same for over seven hundred years. Although the general design has remained the same, the Klingon battle cruiser has evolved both internally, cosmetically, and externally to include the latest in Klingon design. The current evolution, the K't'inga-class, was first introduced into the Klingon fleet in the 2270s as the successor to the D7-class battlecruiser.
With the evolution of nearly every ship-based technology in the Klingon fleet within the twenty years prior the D7 had become nearly obsolete. While the general design of the battle cruiser was still favored as it had been for centuries, it was decided to simply revamp the general design into the K't'inga. Internally it was entirely a new warship, but the most noticeable changes were externally. The K't'inga-class received completely new nacelle designs, new hull markings, and a slightly different "head" configuration.
In 2271 a large energy cloud named V'Ger was discovered penetrating into Klingon space. A wing of three K't'inga-class battle cruisers were dispatched to investigate, but as soon as they intercepted the cloud all three were destroyed. The K't'ingas have continued in service to the present day, having received the normal upgrades and refits over the years. The K't'inga-class battle cruisers were heavily fielded during the Second Federation-Klingon War and Dominion War but fared quite poorly to their newer Vor'cha-class attack cruiser counterparts. They are now considered as second line units, and are generally to be found patrolling friendly borders such as that with the Federation, general exploration, or acting in support of the Vor'cha-class attack cruiser.
