Taiwan’s first indigenous defense submarine prototype, the Hai Kun (SS-711), is to be launched tomorrow and undergo underwater testing next month. It is a major breakthrough in upgrading the nation’s self-defense capabilities, and would make it more difficult for China to blockade Taiwan.
Facing Beijing’s escalating military threats and ambitions of expanding across the Taiwan Strait, a domestically developed submarine was first proposed in the 1990s under then-president Lee Teng-hui (李登輝). The Indigenous Defense Submarine (IDS) program was formally initiated in 2016, as President Tsai Ing-wen (蔡英文) took office, with the aim of creating a fleet of eight domestically developed submarines.
