The ship prefix for ROCN combatants is ROCS (Republic of China Ship) an older usage is CNS (Chinese Navy Ship). The Republic of China Marine Corps (ROCMC) also functions as a branch of the Navy.


Operations include maritime patrols in the Taiwan Strait and surrounding waters, as well as readiness for counter-strike and counter-invasion operations during wartime. Today, the ROC Navy's primary mission is to defend the remaining ROC's territories and the sea lanes under its jurisdiction against any possible blockades, attacks, or invasion. While still sometimes used especially in domestic circles, it is now not as often used internationally due to the current ambiguous political status of Taiwan and to avoid confusion with the People's Liberation Army Navy of the People's Republic of China (PRC). The service was formerly commonly just called the Chinese Navy during World War II and prior to the ROC's retreat from the mainland. The Republic of China Navy ( ROCN Chinese: 中華民國海軍 pinyin: Zhōnghuá Mínguó Hǎijūn), also called the ROC Navy and colloquially the Taiwan Navy, is the maritime branch of the Republic of China Armed Forces (ROCAF).
