Negh'Var class

The Negh'Var-class was a type of large Klingon warship used beginning in the late 24th century. 

Features
The Negh'Var-class was a powerful new form of warship developed by the Klingon Empire in secret, with very few even among the Klingon High Council knowing of the project's existence. It was a significant departure from "traditional" Klingon designs which favored swift, agile vessels, instead offering heavy firepower and pure brute strength.

Negh'Var-class ships were slightly smaller than Starfleet's ships, and were capable of carrying a security detail of 2,700 personnel. They were armed with disruptors, heavy disruptors and photon torpedoes, and were equipped with a cloaking device. 

Kurak, daughter of Haleka was the main designer of the prototype. 



History
The prototype Negh'Var was launched in 2372 and became the flagship for the Chancellor during the Klingon-Cardassian War. 

Negh'Var-class vessels would continue to participate in major engagements at least as late as 2409. 

Mirror universe
The Negh'Var-class was also present in the mirror universe under the command of the Klingon-Cardassian Alliance. Regent $𝜇$ used one of these vessels, also called, for his flagship. The vessel led an attack on $𝜇$ in 2372 but was forced to retreat after suffering heavy damage at the hands of the Terran Rebellion. In 2375 both she and a cloaking device stolen from the prime universe Klingon Empire were captured by the Rebellion. 

In late 2409 several examples of the mirror universe class were captured by the prime universe Klingon Empire and incorporated into the Klingon Defense Force.
