R'daran class

The R'daran class troop transport was a type of support ship used by the Romulan Star Empire.

These were large vessels that were tasked with carrying legions of infantry into the battlefield on alien worlds in order to conquer them for the Romulan people. They possessed practically no armaments which made it essential that these ships were escorted to their destination by warships.
