There are about 170 commissioned ships (with a total displacement of about 181,000 tons) in the ROK Navy, including some 20 destroyers and frigates, 12 submarines, 100 corvettes and fast attack craft as of 2011. The naval aviation force consists of about 70 fixed-wing and rotary-wing aircraft.

Ships

The ROK Navy employs the U.S. Navy-style letter based hull classification symbols to designate the types of its ships and hull number
Hull number
Hull number is a serial identification number given to a boat or ship. A lower number implies an older vessel. The precise usage varies by country and type....

s to uniquely identify its vessels (e.g. DDH 975). The names are that of the historical figures, provinces, cities, counties, peaks, lakes, islands, and birds. The Chief of Naval Operations selects the names of ships.

There are four ship ratings. A first-rate ship (DDG, DDH, Sohn Won-yil class SS, LPH, MLS, AOE, and ARS) is commanded by a captain; a second-rate ship (FF, SS, PCC, LST, and ATS) by a commander; a third-rate ship (SSM, PKG, MSH, and MHC) by a lieutenant commander; and a fourth-rate (PKM and LSF) is commanded by a lieutenant.
