By unnamed class

Battle cruisers

In 2364, a contingent of seven battle cruisers converged on a Federation border outpost. While the outpost called for reinforcements from the nearby USS Berlin and USS Enterprise-D, the encounter ended without incident. (TNG: "Angel One")

These battle cruisers were only mentioned in dialogue.

Command ship

Ship's captain aboard his vessel

This command ship covertly participated in the genetic puzzle that was being uncovered by Professor Galen in 2369.

According to the ship's captain, they had intercepted several communiques between the Yridians and Cardassia. He was later present, while under cloak, when Professor Galen's shuttlecraft was attacked.

As the USS Enterprise-D picked up the mission where Galen left off, this ship shadowed the Enterprise, eventually arriving at Vilmor II, where the captain and a few of his crew surprised the Cardassian, Klingon, and Federation delegations that were present there, as they were attempting to discover the secret of the genetic codes that led them to the planet.

The ship's captain later contacted Captain Jean-Luc Picard to inform his that his ships were leaving orbit for Romulan space. (TNG: "The Chase")

These ships were only mentioned in dialogue.


In 2365, Captain Donald Varley recorded a personal log aboard the USS Yamato stating that they had "been spotted by a Romulan cruiser, but after playing hide and seek through several solar systems" he thought they had lost them. (TNG: "Contagion")

This cruiser was only mentioned in dialogue.
This vessel may have also been the Haakona, a Romulan vessel described as a "battle cruiser" that appeared immediately following the destruction of the Yamato.


This flagship lead the Romulan forces at the Battle of Cardassia, where it was destroyed by Dominion forces during a heavy assault that saw the Romulan lines collapse. (DS9: "What You Leave Behind")

This flagship was only mentioned in dialogue.
The flagship was identified as being the D'ridthau (β) in an early draft of "What You Leave Behind". Later revisions removed the name from the script and the name survived only in the pronunciation guide of the episode. However, in the novelization of What You Leave Behind , the name of the flagship was retained and mentioned by Admiral Ross. The D'ridthau may have been of the D'deridex-class, which was the only Romulan starship class visible, or an entirely unknown class altogether.
The Star Trek Customizable Card Game gives this ship's name as Rovaran.

Patrol ships

Starfleet mission archive referencing ships

In 2346, several of these patrol ships, presumed to be Romulan Warbirds, attacked the Klingon colony on Khitomer after having received the defense access code from the outpost. These ships were able to lower the outpost's shields, and destroyed the outpost.

Twenty years later, one of these ships was captured, and contained the logs that provided new information to the Klingon High Command on the Khitomer attack. These logs, according to Data, "clearly indicate a transmission from the outpost to the Romulans moments before the shields dropped." The High Command had learned of the treachery, but according to K'mpec, "only the council knew whose security code had been transmitted. Ja'rod, father of Duras."

Since the House of Duras was powerful, according to K'mpec, "if the truth were known, it would shatter the council, almost certainly plunge us into civil war." Because "someone had to be blamed," the Council revealed that Mogh was responsible for the treason, and since Worf was in Starfleet, they "did not expect [him] to challenge the judgment." (TNG: "Sins of the Father", "Redemption")


This transport delivered Ruwon and Karina to Deep Space 9 in 2371. Upon their arrival, they were routed to Docking Bay 12. (DS9: "Visionary")

This transport was only mentioned in dialogue.


This vessel was defeated by the USS Enterprise, using the Cochrane deceleration maneuver, near Tau Ceti in the late 2260s. (TOS: "Whom Gods Destroy")

This vessel was only mentioned in dialogue.
