The South Korean navy includes the Republic of Korea Navy Headquarters, Republic of Korea Fleet, Republic of Korea Marine Corps, Naval Education and Training Command, Naval Logistics Command, and Naval Academy. The Chief of Naval Operations (CNO) is the highest-ranking officer of the ROK Navy.
The ROK Navy operates several naval bases in South Korea: Jinhae, Busan, Donghae, Pyeongtaek, Mokpo, Incheon, Pohang, Jeju Island, Baengnyeong Island. Jinhae has been the major port for the ROK Navy since the establishment of the Korean Coast Guard by hosting vital naval facilities including the Naval Shipyard; the Jinhae Naval Base Command is responsible for protecting the area. The Busan Naval Base has become another major naval base for the ROK Fleet since its Command Headquarters moved from Jinhae in 2007. Donghae, Pyeongtaek, and Mokpo hosts the command headquarters of the First, Second and the Third Fleet respectively. Incheon hosts the Incheon Naval Sector Defense Command responsible for protecting littoral waters close to Seoul, the nation's capital.
Naval air stations are in Pohang (K-3), Mokpo (K-15), and Jinhae (K-10).
