Technical data
Sech was the Klingonese word for "torch". (Star Trek: Klingon scale chart partwork)

The Sech-class sported a compact triangular hull design with a flat profile, with the tip forming the bow. Most of it appeared covered in gold-like hull plating. However, large portions of the wings glowed deep blue under light. A trio of engine exhausts marked the rear-most point of the ship. A rectangular engine exhaust sat underneath the engine tubes. The highest point of the ship sat atop the dorsal center. 

The ship had a length of 558.8 meters. (Star Trek: Klingon scale chart partwork)

Vessels of the class were warp-capable and carried Klingon raiders as auxiliary craft. The Sech-class carried a crew of about 40-50. At least one ship served as a prison ship. 

Its disruptor arrays fired green bolts from the front of each wing. 

Service history
On 11 May, 2256, at least one Sech-class battlecruiser was part of the reinforcements joining the Klingon fleet of 24 Great Houses at the Battle of the Binary Stars against Federation Starfleet forces. 

Soon after, L'Rell of the House of Mo'Kai commaned a Sech-class battlecruiser that served as prison ship for captured Federation citizens, including Harry Mudd. After her compatriot Voq was artifically hybridized with Lieutenant Ash Tyler of the USS Yeager (NCC-1437), the sleeper agent was held as a prisoner.

In December 2256, L'Rell's battlecruiser captured $𝜇$, and his shuttle identified the ensnaring tractor beam with a signature. With the help of "", Lorca escaped L'Rell and her ship aboard a Klingon raider. He and the new Tyler returned to USS Discovery (NCC-1031).
