- Nachthexen translates from German as "night witches".
One of the Nachthexen-class battlecruisers was the USS Defiant-C, under the command of Captain K'grel, daughter of Korol. The Defiant was the ship that took down the NV General Vosk, a Na'kuhl dreadnought and flagship of the battle group Virtuous Destiny.
By the time of the Battle of Procyon V, Defiant-C was a formidable ship of the 5th Temporal Fleet. The Defiant was torn asunder by the Na'kuhl destroyer NV Salvation. (STO website: No Profit But The Name)
