The Klinzhai class was a type of Klingon command battlecruiser starship in Klingon Defense Force service in the early 25th century. The Klinzhai-class was one of three KDF command battlecruisers and had a counterpart in Federation Starfleet and the Romulan Republican Force, respectively. All of the command battlecruisers were tier 6 starships and required a commanding officer ranked lieutenant general or higher. (STO video game: Delta Rising)
The Klinzhai class was designed by KDF based on specification shared by the Starfleet Corps of Engineers in 2410, and launched in the same year. The development project was a cooperative effort between the Alpha Quadrant Alliance members, which saw the production of a total of nine ship classes, three per member state. One class of each faction was geared towards engineering, tactical and science. The Klinzhai-class command battlecruiser was geared towards science, which was reflected in its bridge officer stations allocation.
The Klinzhai-class command cruiser was a tier 6 starship type and required a commanding officer ranked lieutenant general or higher. The ship's crew complement topped at 1.500. The ship had four aft and fore weapon slots each. Standard equipment included disruptors and photon torpedo launchers but the ship was also able to mount dual cannons. During combat, the command battlecruiser would launch four To'Duj-class fighters from its single hangar bay. In addition, standard equipment of the Klinzhai-class starship included the tachyon pulse platform, a mobile weapons platform.
The bridge was staffed by one commanding officer, one commander specializing in engineering and command division; one lieutenant commander science officer, one combined command/tactical officer (lieutenant), one engineering lieutenant and one lieutenant of any department.
A new technology introduced with the command battlecruisers were inspiration abilities. During combat, the Klinzhai-class battlecruiser could inspire nearby allies with several abilities: turn the tide, against all odds, and battle preparation. Other enhancements of the class included absorptive and enhanced plating, enhanced weapon banks, armored hull and improved brace for impact. The command battlecruiser was equipped with a two-geared cruiser communications array, allowing for shield frequency modulation and the ability to attract fire. (STO video game: Delta Rising)
In the 25th century, the design of the Klinzhai-class command ship allowed its commanding officer to choose from different designs of livery, which could be modified further at starbases. These options were designated Type 1-5 and Veteran. (STO - "Empire" mission: "The Hunt is On")
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")
