MS3 is the old rate/rank for a Mess Management Specialist (MS) Third Class (Petty Officer), or a Navy Cook. The rate was changed to "Culinary Specialist" (CS) in 2004, no doubt to make it sound more professional and appealing for recruiting purposes.
It does not stand for anything. The word navy is derived from the Latin word navigia meaning ships.
