Romulan Republic Navy

The Romulan Republican Force, or RRF for short, was the military defense organization of the Romulan Republic. Its original headquarters were a fleet of ships in the middle of space, the Romulan Flotilla, before a permanent base of operations was established on Dewa III, the new Romulan homeworld. The RRF had its own uniform from the start. 

History
The RRF was established sometime in early 2409, or before. By February 2409, the RRF maintained an ever increasing fleet of starships appropriated from the Tal Shiar, or former Romulan Star Navy vessels. These vessels operated throughout official Romulan Star Empire space and sought out independent Romulan colonies in the Tau Dewa sector block. One such world was Virinat, were an RRF ship helped spoiling a joint Tal Shiar/Elachi invasion of Virinat. The Virinat survivors were invited to join the Republic's efforts to fight back the Tal Shiar. 

To gain legal recognition from neighboring powers, the Proconsul of the Romulan Republic, D'Tan, tasked the RRF with finding a suitable world to colonize. The RRF picked the unclaimed, lush planet Dewa III. The Republic named Dewa III its capital, and designated as New Romulus, joint homeworld of the combined Romulan and Reman people. 

Leadership of the RRF passed from Commander Temer to Subcommander Nadel when Temer sacrificed himself at the international conference on Khitomer to save Klingon Councilor Wodan's life. The United Federation of Planets and the Klingon Empire subsequently became allies of the Romulan Republic. Because of the state of war between the UFP and the Empire, and limited resources available to the Republic, RRF officers had to pledge allegiance to either Starfleet or the Klingon Defense Force, gaining access to the respective forces' equipment, personnel and installations. 

The Republic rose to become a major power in local space, and the RRF expanded quickly. Shipyards were established on New Romulus, and new starship classes unique to the Republic were introduced. Admiral Kererek assumed command of the RFF, and a flagship, the, was commissioned. ( et al.) The Republic's influence expanded further when it gained access to the Solanae Dyson Sphere in the Delta Quadrant, and the RFF assumed command of Allied Joint Command. The commanding officer of the SDS became Romulan Commander Kaol.
