S'Kul class

The S'Kul class was a Fek'Ihri starship type, a fighter class in Fek'Ihri Horde service from the 2400s decade. Vessels of this class were auxiliary craft launched from battle carriers and  dreadnoughts. 

History and specifications
The Klingon Defense Force first encountered the S'Kul class in the Boreth system, when these fighters and tortured souls were launched from a Kar'Fi-class battle carrier in 2409. While S'Kul-fighters were the smallest known Fek'Ihri ship type, tortured souls were Fek'Ihri invidiuals able to withstand the hostile environments of space.

The fighters were equipped with antiproton dual cannons and a chroniton torpedo launcher. Both weapon emplacements were forward-facing. Unlike other known fighters of that year, S'Kul fighters were capable of using ramming speed to deal physical damage to other vessels.

Ships of this type echoed the design language of other spacegoing Fek'Ihri vessels: a prominent red deflector dish at the bow, embedded between dark gray plates and tendrils. The impulse engine, situated at the rear, exuded a fiery red-and-pink plasma stream that made it look like the ship was riding on fire. 

The KDF captured Kar'Fi-class battle carriers and retrofited them for service for the Klingon Empire. These captured ships were equipped with a single hangar bay, housing two wings of S'Kul fighters, which could be replaced by a frigate. 

Servie history
The Fek'Ihri returned in 2409 and attacked the Klingon Empire in an attempt to ursurp it and restore Molor to the Klingon throne. 

The Horde blockaded the orbit of Boreth to prevent Emperor from reaching the Boreth Monastery. A KDF vessel broke through the blockaded by engaging and destroying the Fek'Ihri ships. These included a Kar'Fi-class battle carrier that sent tortured souls and S'Kul fighers against the Klingon forces. The KDF gained the ability to deploy S'Kul-fighters, but not tortured souls, from captured Kar'Fi battle carriers. 

In the followng years, ships of the class were seen again in attacks on the Klingon Fleet Starbase. 

The Alpha Quadrant Alliance continued to practice fighting against ships of the Horde in the holographic scenario Combat Simulation 347.
