Военно-морские силы Китайской Республики (Тайвань)

The Republic of China Navy (ROCN) is the maritime branch of the Republic of China Armed Forces. The ROC Navy's primary mission is to defend ROC territories and the sea lanes that surround Taiwan against a blockade, attack, or possible invasion by the People's Liberation Army Navy of the People's Republic of China. Operations include maritime patrols in the Taiwan Strait and surrounding waters, as well as counter-strike and counter-invasion operations during wartime. The Republic of China Marine Corps functions as a branch of the Navy.

The ship prefix for ROCN combatants is ROCS (Republic of China Ship); an older usage is CNS (Chinese Navy Ship).
