IKS Nav'Don

The IKS Nav'Don was a ship in service to the Klingon Defense Force in the 24th century, until its destruction in a patrol run.

During a patrol run in the Hydran border, she engaged the HMS while the latter was testing its experimental cloaking device. It was destroyed in a life-and-death battle against the Hydran galactic survey cruiser in an attempt to enforce the Treaty of Oxvind. Because it lacked attack fighters of its own, the Klingons were severely outgunned.

Backgound
As the first ship to bear the name was destroyed in battle against the Vosteage in Hydran space, it is presumed that there was a second ship of that class built by 2377 because there was an IKS Nav'Don in the video game.
