Taiwan is set to embark on a significant modernization of its naval air defense systems by producing between 1,200 and 1,376 Hai Chien II (Sea Sword II) missiles. This initiative aims to enhance the navy’s capabilities and standardize missile systems across its surface fleet. The decision comes on the heels of successful live-fire tests of the Hai Chien II, a naval adaptation of the Tien Chien II air-to-air missile, conducted off the southern coast of Taiwan.
Defense officials have indicated that the new missile system is poised to replace outdated air defense weapons currently in service on naval vessels, which are deemed insufficient against contemporary aircraft and evolving aerial threats. The navy’s current and future warships, such as Kang Ding-class frigates, next-generation light frigates, Tuo Chiang-class corvettes, and Yushan-class amphibious landing platforms, will require 688 Hai Chien II missiles to be fully equipped according to military planning estimates.
To ensure readiness for sustained combat operations, military logistics assessments suggest maintaining stockpiles that are 1.5 to 2 times the necessary operational missile count. This strategic reserve planning contributes to the higher production target. The Hai Chien II is designed for seamless integration with ship-based vertical launch systems, offering vessels enhanced range and comprehensive 360-degree air defense coverage. This modernization effort is expected to significantly bolster the fleet’s capability to counter aircraft, drones, and missile threats.
Moreover, Taiwan is upgrading its Kang Ding-class frigates with new launch systems to accommodate multiple Hai Chien II missiles, while future warship designs are being developed with this missile as a core element of their air defense architecture. This initiative is part of Taiwan’s broader strategy to fortify its maritime defense in response to escalating military activity and security challenges in the region.
