China's new Type 039C Yuan-class submarine, designed with stealth features, is believed to have been deployed in simulated Taiwan blockade exercises. It boasts an angled sail for reduced detectability and is likely to have similar weaponry to its predecessors. The vessel may undergo upgrades with lithium-ion batteries for enhanced acceleration and endurance. In a Taiwan blockade, conventional submarines could play a critical role in targeting ships entering and exiting Taiwan's ports. The US and its allies may face challenges in countering China's high-tech conventional submarines.
