The Sword of Kahless-class, or qeylIS BetleH-class, were a type of Klingon Empire battleship starship used by the Imperial Fleet during the 2290s decade. They were, at the time, one of the largest class of vessels within the Klingon Defense Force.
History and specifications[]
At first, there were only two ships of this class produced and active in service, one of which was the flagship and was commanded by the chief of staff. Their production caused much outrage among the members of the Klingon High Council who felt that that the ships were too costly to produce.
They were large bulky designs equipped with six warp nacelles. They also possessed a heavy assault phaser that was capable of breaking the shields of starbases and heavily fortified locations. This weapon had a slow recharge rate, requiring 30 seconds before each weapon burst. Furthermore, a feedback could be implemented to increase the weapon's damage potential. Despite its strong firepower and defenses, the qeylIS BetleH was very slow due to the space devoted to the ships' weapons arrays. This made attacks on the ships near suicidal to enemy commanders, especially at the bow of the craft. (ST video game: Klingon Academy)
