Qi'moh class

The ***QIHmoH Segh*** or ***Qi'moh*-class**, tlhIngan Hol for "damage dealer" or "devastator," was a type of spacecraft developed within the Klingon Empire in the mid 22nd century. It was originally named the **K4B-class** by Starfleet, as it was encountered after its freighter variant, but was reclassified as **D5A-class** when that service restructured its classification system.

## History

The *Qi'moh*-class began development when the Klingon High Council determined that a more powerful warship was needed to fully conquer the B'Moth system and subdue its inhabitants. The first battlecruiser left the DaQ'yan Forge in 2126 and was extremely successful in early engagements with rebellious elements of the al'Hmatti. Dozens of space frames began construction and over forty were in service by 2130, with the Qi'moh quickly replacing the *D'ama*-class as the favored warship in the Imperial Fleet.

A program to retrofit *Qi'moh* cruisers with deflector shields began in 2146 after Klingon engineers salvaged and reverse-engineered defensive shield systems from a Vulcan vessel captured on the outskirts of the Kronos system.

### *Pip'a*

Two decades after its introduction, the *Qi'moh* design was adapted as a freighter. The new *Pip'a*-class (*pIp'a'*) first saw service in 2148. Given a name meaning “strong spine,” the refit *Qi'moh* spaceframe was a vital element in supporting Imperial expansion and fleet logistics.

### *Yoj*

Following traditional Klingon practice, many *Qi'moh*-class vessels received significant refits in the mid 23rd century. The new design, named the *Yoj*-class, meaning “judgment,” saw most of its service along the Klingon Empire’s border with the Romulan Star Empire.
