Taiwan’s Impossible Naval Dilemma: Blue-Water Navy vs Porcupine Defense

Taiwan’s Republic of China Navy faces a critical strategic dilemma as it balances asymmetric coastal defense against China’s PLA Navy with traditional blue-water sea control. Western defense strategists strongly advocate for a porcupine defense posture. This approach leverages low-cost, highly survivable assets such as the stealthy Tuo Chiang class missile corvettes, Kuang Hua VI speedboats, land-based anti-ship cruise missiles, and sea mines designed to saturate the Taiwan Strait and deny amphibious invasion routes. However, relying exclusively on these relatively immobile systems leaves Taipei completely vulnerable to Beijing’s aggressive grey-zone tactics. Daily incursions by warships and coast guard cutters demand a visible, endurance-capable surface fleet to escort civilian shipping, resupply offshore islands like Kinmen, and prevent non-kinetic blockades. Taiwan’s legacy surface fleet, comprising the aging Kee Lung class destroyers alongside Knox and Perry-class frigates, suffers severe operational strain under Mainland China’s strategy of resource attrition. To bridge this gap, Taiwan is pursuing a dual-tier modernization strategy, constructing light frigates, indigenous Hai Kun-class attack submarines, and next-generation main surface combatants to ensure both wartime survival and peacetime authority.
