Kaohsiung: Taiwanese shipbuilder CSBC Corp., Taiwan announced its goal to deliver its first domestically built submarine prototype, Hai Kun, before the end of June. This announcement came after the vessel completed its fourth submerged test earlier in the day.
According to Focus Taiwan, CSBC Chairman Chen Jeng-horng detailed plans for the prototype, known as Narwhal in English, to undergo a series of submerged tests with increasing depth. Chen addressed media reports about the anticipated delivery to the Navy by June, stating that the timeline is plausible and that the company is aligning with the Navy's requirements. He acknowledged the delay in delivery and emphasized the importance of meeting safety and quality standards, noting the extensive documentation required for the delivery process is still ongoing.
The submarine embarked on its fourth submerged test from Kaohsiung Harbor at around 9 a.m., attracting military enthusiasts who showed support for Taiwan's indigenous submarine program. CSBC President Tsai Kun-tsung reported that during these trials, the vessel's snorkel mast and periscope reached depths of 10 to 20 meters, with previous dives extending to several dozen meters, showcasing the submarine's watertight integrity.
Tsai explained that the pressure hull's tolerance is crucial for distinguishing shallow and deep dives, but as long as the submarine remains within its design depth, there should be no issues. Regarding its weapons systems, Tsai disclosed that the first prototype employs imported torpedo tubes, with plans for domestically produced tubes in future models, although details remain confidential due to potential repercussions from China.
According to the Ministry of National Defense (MND), the testing schedule for the Hai Kun was initially set for completion by September last year, aiming for a November 2025 delivery. However, significant delays have occurred. Tsai mentioned penalties for the delays, with daily fines of approximately NT$190,000 (US$5,995), resulting in more than NT$38 million due to an anticipated 210-day delay if the submarine is delivered by the end of June. He emphasized the company's focus on safely completing the submarine to high standards, benefiting both the nation and CSBC.
