Later in 2410, the military was referred sometimes to as Romulan Republic Navy but retained the RRF abbreviation. ( STO missions: ' Sphere of Influence', ' Circles within Circles') The commanding officer of the SDS became Romulan Commander Kaol. ( STO mission: ' New Romulus Aid' et al.) The Republic's influence expanded further when it gained access to the Solanae Dyson Sphere in the Delta Quadrant, and the RRF assumed command of Allied Joint Command. Admiral Kererek assumed command of the RRF, and a flagship, the RRW Lleiset, was commissioned. Shipyards were established on New Romulus, and new starship classes unique to the Republic were introduced. The Republic rose to become a major power in local space, and the RRF expanded quickly. ( STO missions: ' Turning Point', ' Neutral No More') 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 United Federation of Planets and the Klingon Empire subsequently became allies of the Romulan Republic. 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. ( STO mission: ' The Search of New Romulus') The Republic named Dewa III its capital, and designated as New Romulus, joint homeworld of the combined Romulan and Reman people. The RRF picked the unclaimed, lush planet Dewa III.

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