Taiwan's first domestically built submarine is almost certain to miss the date that sea trials were scheduled to begin, with only one day remaining until the deadline.
According to the timeline set by the Ministry of National Defense (MND), sea trials for the Hai Kun (海鯤), or “Narwhal,” Taiwan's Indigenous Defense Submarine (IDS) prototype, were supposed to begin this month and be completed by Sept. 30.

"April was the original goal... We are currently working on improvements and final calibrations to meet the requirements set for sea trials. That is our main goal," navy Chief of Staff Chiu Chun-jung (邱俊榮) said yesterday at an MND news conference when asked whether the schedule had been delayed.
Pressed to say whether the MND would fail to deliver on its word, Chiu said the navy is focusing on reaching the "technology readiness level required for the vessel to go out to sea, not on the schedule."
The MND had said on several occasions that sea trials would begin this month, in response to news reports that tests regarding the Hai Kun had experienced setbacks.
On Feb. 26, it said that harbor trials were on schedule and sea trials would proceed as planned this month, amid reports of potential testing delays due to voltage surges from a land-based power supply used in testing causing some components in the submarine to fail.
The IDS program has faced several delays.
Three days prior to the unveiling of the prototype at a photo op attended by then-president Tsai Ing-wen (蔡英文) in September 2023, Huang Shu-kuang (黃曙光), then convener of the program, said the prototype would undergo a harbor acceptance test beginning on Oct. 1, 2023.
That would be followed by a sea acceptance test, and the submarine would hopefully be delivered to the navy before the end of last year, Huang said.
At some point last year, the scheduled delivery was pushed back by about a year, to November.
Given that timing, and the MND's acknowledgement in September last year that the Haikun had failed more than 10 categories in the harbor trials, the Chinese Nationalist Party (KMT) and Taiwan People's Party took aim at the submarine's budget in January.
Lawmakers from the two parties voted to freeze NT$2 billion (US$61.91 million) of the funding proposed for this fiscal year for the IDS program, or about half of the proposed total, with the proviso that the funds can only be unfrozen after the submarine passes the sea trials.
Chiu said yesterday that the funding would be unfrozen if sea trials are finished on time and the MND gives a briefing about them at the legislature.
Minister of National Defense Wellington Koo (顧立雄) told reporters at the legislature last week that the submarine's contractor, CSBC Corp, is to face a fine if it fails to deliver the sub to the navy in November, as per the contract.
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
