The Fek'Lhr Strike Cruiser was born from the reality of the Dominion War. One of the next generation of Klingon cruisers, the Fek'Lhr is a close relative of the Vor'Cha and her sister hulls. The most visibly different aspect of the Fek'Lhr is the large, elongated forward hammerhead in which much of the ship's heavy weaponry are housed.

The Fek'Lhr Strike Cruiser has firepower rivaling that of the Vor'Cha Attack Cruiser, most appreciably in its torpedo armament. The Fek'Lhr, however, was built even more for speed than for firepower. This ship is equipped with one of the most advanced engine systems in the Klingon navy, allowing it to be both faster and more maneuverable than any other Klingon cruiser in the fleet.

Typically, Fek'Lhr Strike Cruisers operate alone on the borders of the Klingon Empire where their speed and combat prowess are utilized for fast raids into enemy space to destroy key strategic targets.
