A ship prefix is a group of letters, typically an abbreviation, that some factions insert into the names of their military and/or civilian ships.
A ship prefix is a combination of letters, usually abbreviations, used in front of the name of a civilian or naval ship. Prefixes for civilian vessels may either identify the type of propulsion, such as PS for paddle steamer, or purpose, such as RV for research vessel.Civilian prefixes are often used inconsistently, and frequently not at all. Sometimes a slash is used to separate the letters, as in M/S.n the United States Navy that prefix officially only applies while the ship is in active commission, with only the name used before or after a period of commission and for all vessels in service rather than commissioned status.
