In Northeast Asia, Taiwan recently launched its first domestically built Hai Kun-class submarine, aimed at enhancing its naval capabilities and defense posture. This submarine is equipped with advanced US-designed torpedoes and anti-ship missiles and reflects Taiwan’s focus on countering potential threats from China.
Japan has been commissioning new Taigei-class diesel-electric attack submarines, showcasing its shipbuilding capabilities and technological advancements in stealth and sensor systems. These new submarines have improved features and weaponry, including vertically launched missiles for enhanced operational capabilities.
South Korea has continued expanding its submarine fleet, launching the latest Dosan Ahn Changho-class submarine, ROKS Shin Chae-ho, with advanced features like air-independent propulsion systems and vertical launch tubes for conventionally armed ballistic missiles.
Across Southeast Asia, Singapore stands out for launching its Invincible-class diesel-electric submarines, featuring advanced automation and propulsion systems, customized for operating in warm, shallow waters in the region. These submarines are part of Singapore’s efforts to bolster its maritime defense capabilities and replace aging subs.
Other countries like the Philippines, Indonesia, and Thailand are also investing in new submarine capabilities in response to regional security challenges and to modernize their respective naval forces. These developments signify a broader trend in East and Southeast Asia of enhancing undersea capabilities in the face of evolving security dynamics.
Overall, the pursuit of submarines by these countries underscores the strategic importance of undersea warfare in the region and reflects their efforts to safeguard territorial interests, ensure maritime security, and adapt to evolving geopolitical realities.
