List of ships of the Republic of Korea Navy
# List of ships of the Republic of Korea Navy

The Republic of Korea Navy was established on November 11, 1945, as the Marine Defense Group (later became the Korean Coast Guard) after Korea was liberated from the Empire of Japan on August 15, 1945. The Korean Coast Guard became the Republic of Korea Navy after the South Korean government was established on August 15, 1948.

Since its inception and until the 1990s, the Republic of Korea Navy had acquired about 150 former United States Navy ships. As South Korea's economy grew, the ROK Navy was able to build larger and better equipped fleets with local shipbuilders.

The ROK Navy employs the U.S. Navy-style letter based hull classification symbols to designate the types of its ships and hull numbers to uniquely identify its vessels (e.g. DDH 975). The names are that of the historical figures, Navy heroes, provinces, cities, counties, peaks, lakes, islands, and birds. The Chief of Naval Operations selects the names of ships.

The ship prefix for all the commissioned ROK Navy ship is ROKS (Republic of Korea Ship) when the names of ships are written in English.

## Ships acquired before and during the Korean War

The Republic of Korea Navy was established as the Marine Defense Group on November 11, 1945. In June 1946, the Marine Defense Group became the Korean Coast Guard, and officially recognized by the United States Army Military Government in Korea. The Korean Coast Guard acquired 36 patrol craft (mainly ex-IJN and USN minecraft) through the Military Government. In October 1949, the ROK Navy purchased a 600-ton submarine chaser, the former USS PC-823, which was renamed as ROKS Baekdusan (PC 701) and became "the first significant warship of the newly independent nation". The Navy purchased three additional PC-461-class submarine chasers before the Korean War, which began on 25 June 1950 when North Korea invaded South Korea.

A total of 76 ships acquired: 5 PF, 6 PC, 4 PCS, 4 PT, 2 GB, 2 PG, 5 LST, 4 LSSL, 6 LCI, 18 YMS, 11 JMS, 5 AKL, 2 AO, 1 YO, 1 LT
