The Sea Oryx is an indigenous short-range air defense system intended for the Taiwanese Navy. It is planned to be installed on Taiwan’s Navy Catamaran Corvette “Tuo River.”[i]The system has a pivotal multi-axis launcher capable of firing 8 or 16 ready-to-fire missiles.[ii]The launcher also has a forward looking infrared sensor on its side.[iii]

The interceptor for the Sea Oryx is an upgraded variant of the short-range Tien Chien-1 missile. The missile is equipped with an imaging infrared seeker, inertial navigation system, data-link system and an enhanced rocket motor.[iv]

Strategic Implications

Strategically, the Sea Oryx provides Taiwan with an indigenous air defense capability for its naval vessels. The system has a high ready-to-fire arsenal which increases its ability to intercept a large number of threats. It also has a reduced engagement reaction time when it operates in the lock-on-after-launch mode.[v]
