Sometime prior to stardate 3714.28, USS Yorktown, commanded by Captain Eric von Ryan, discovered the damaged, uninhabited hull of IKV Krieger, a Klingon D7-class battlecruiser near Starbase 16. The ship was used to add to Starfleet's intelligence on the class of ships. (Star Fleet Assembly Manual 2)
Following the Klingon-Romulan Alliance in 2268, a number of D7 class vessels were given to the Romulan Star Empire. (TOS: "The Enterprise Incident") As part of the trade the Romulans shared their cloaking technology with the Klingons. (Ship Recognition Manual, Volume 4: Starships of the Original Series Era)
For much of the 23rd century, the D7 was the standard cruiser of the Klingon Defense Force. It was considered less expensive than most other heavy cruisers or battlecruisers, it also lacked the full range of scientific capabilities and the crew living conditions were spartan by Federation or Lyran standards. In combat, the D7 was noted for its superior turn rate and for its many transporters, which made it effective for hit and run raids.
This ship was not intended as a long–range bombardment platform like the D6D, but was an experiment to produce a more effective cruiser for general combat purposes. If the experiment had been completely successful, many or most of the D7s would have been converted to this design. The lack of the rear–arc defenses was accepted by the captains but rejected by the admirals.
These excellent ships represented the command version of the basic D7 design. Shields and weapons were improved. These ships never received the "B–refits". The equivalent improvements had been incorporated into the original design.
The design department of Kareli Space Yards, exploring further enhancements of the venerable D7 hull, incorporated several innovative features into the D7W, making it equal to the Federation's Gettysburg-class. This was the most powerful D7 variant ever produced. It was designed as heavy command cruisers.
Among the ships transferred by the Klingons were three D7 battlecruisers. These were converted to Romulan technology and deployed as a single squadron on the Federation border. KR-variant D6s could not be converted to the K7R.
This was a conversion of the Klingon D7C command cruiser, three of which were purchased by the Romulans. It entered service as the KRC with Type–G torpedoes and was later refitted with the Type–S torpedoes.
- It is assumed that the D7 in Eidolon (Bouteina episode) was either a K7R or a KRC since it was escorting a Romulan convoy.
