IKS Azetbur (Negh'Var class)

The IKS Azetbur was a Klingon Defense Force battlecruiser in service in the 2400s.

History
When a KDF captain was sent to infiltrate the Vault in a shuttle in 2409, the Azetbur was placed on standby in nearby space to help cover the infiltration team's escape in the event of an emergency. When Obisek ordered his forces to attack the infiltrators to cover the escape of a warbird carrying thalaron weapons, the Azetbur warped into the system to intercept the warbird. With the away team covering the battlecruiser's flanks from their shuttle, the Azetbur was able to destroy the warbird. 

Background
The Azetbur is almost certainly named for Azetbur, daughter of Gorkon, Chancellor of the High Council of the Klingon Empire from 2293 to 2311.
