This is another ship that apparently appeared in Captain's Log for AE/NE.

The Klingon's ran their space navy differently from the Federation (and most other races) in that they did not follow the same procession of ship classes. They never had a light cruiser, preferring to use the D6 to fulfill that role, and the D7 Battlecruiser was comparable to the heavy cruisers of other races, with the C7 BCH the "natural enemy" of the Fed BC. A similar situation existed with the Klingon's smaller ships. Traditionally, they eschewed the destroyer class, allowing their excellent F5 Frigate to fulfill the roles of both destroyers and frigates in their fleet. With the coming of the General War, however, the need for a true destroyer that could take on the new war destroyers of their enemies became obvious. The F5W Destroyer - referred to as "the ship the F5 was born to become" - fulfilled that need.

NOTE: According to both SFB Module MO3: Captain's Starship Registry, and the Starship Name Registry (both available on ADB's website), there is no "class ship" for the F5W, so I have not included a class name.
