The D7M-class (known in Klingon languages as K't'inga-class, K'tinga-class or K'Tinga-class, literally translated from the Klingonese language as Bringer of Destruction-class) battle cruiser was a primary class of warship in service with the Axis Navy and later the Imperialists, it was also used by the Horde (mainly the Rebels led by Duras, son of Ja'rod). The K't'inga-class cruiser was one of the most advanced and versatile warships in the Klingon Imperial Fleet. Although the tactical effectiveness of the K't'inga relative to other ships was never firmly established in true canon, it was capable of challenging a Victory-class star destroyer without fear, threatening an MC80a class cruiser in a stand-off situation, and in small numbers it could inflict severe damage on an MC80a star cruiser. During the Second War, many of the K't'inga class ships are replaced by its improvement version, the K'beajQ class. Kronos One and Azshara is perhaps the most well-known K't'inga class ships
The outboard plan of the K't'inga design incorporated the same basic shape and classic design lineage dating back over one hundred years to the D5 class battle cruiser. The K't'inga-cruiser was a direct offshoot in design-lineage from the venerable D7 class battle cruiser introduced sometime prior to 1599 N.E.
The bulk of the ship's overall mass was incorporated in the aft section of the ship. The bridge module was located on a bulbous forward section, which was separated from the aft section by a relatively thin connective section that attached to and flared into the aft section. Located on the caudal section of the ship were the ship's impulse engines. Jutting from below the port and starboard side of the ship's aft section were the ship's warp nacelles. Aside from possessing a slightly sleeker shape and contour than its D7-class predecessor, the most notable design variations between the two classes included a less bulbous forward section, a larger bridge dome, differently-designed warp nacelles, and more extensive external hull plating.
