Every vessel and outpost in Starfleet is assigned a diplomatic grade by the Federation.  These grades serve to gauge a vessel's political and
diplomatic capabilities.  A low-rated starship is typically used to ferry diplomats over a short distance, while higher-rated starships can host
large political summits and participate in negotiations with alien species.  Starships are not required to be an exact match to achieve a
certain grade; a vessel must simply fall within the general level of capability implied by the said grade.
