IKS Dakronh

The IKS Dakronh was a Klingon B'rel class bird-of-prey that was operational in 2293.

The Dakronh was modified to fire it weaponry whilst cloaked. This made the ship extremely useful to the conspirators attempting to prevent a Klingon-Federation rapproachment following the destruction of Praxis, including a major role in the assassination of Chancellor Gorkon. While it initially had a tremendous advantage, once Federation personnel figured out the Dakronh 's capabilities, it proved to be vulnerable to scientific sensors routinely carried aboard Federation exploration vessels and was was destroyed.
