Talk:Romulan nomenclature

RIS prefixes on Romulan ships are used throughout the Starfleet Command series. Not only they were used in SFC3, in the TNG era, but also in SFC1/2, both of which are set in the TOS era. Therefore it means that the RIS prefix saw its debut by the second half of the 23rd century.– Vika-crow 03:22, September 6, 2009 (UTC)
