The Coalition starship USS Runemark faced down a vessel of the Romulan Star Empire at Canis Minoris XII during the Earth-Romulan War. On reference stardate 0101.28, the Runemark was destroyed after a running battle with a Romulan-crewed U4-class cruiser. Despite the Runemark's destruction at Canis Minoris XII, the Zoenamy-class vessel's Centauran crew were successful in severely damaging the Romulan ship. (FASA RPG module: The Romulan War)
- The source material specifies Federation allegiance for all allied vessels in the Romulan War, but later canon contradicts this in stating that this was prior to the Federation founding. In accordance with the canon version, these vessels are referred to as Coalition of Planets allies for the purposes of this wiki.
