Taiwan has introduced its first domestically-produced submarine as part of its efforts to bolster its defense against potential Chinese aggression. The launch ceremony was presided over by President Tsai Ing-wen in Kaohsiung, with the new submarine set to undergo testing before being delivered to the navy by the end of 2024. The submarine, named the Haikun, is part of Taiwan's goal to eventually operate a fleet of 10 submarines equipped with missiles.
