Harbor acceptance tests (HAT) for the indigenous Hai Kun (海鯤), or Narwhal, submarine are 50 to 60 percent complete, a navy official said today, refuting rumors that there were 70 aspects that needed to be improved.
The Hai Kun, Taiwan’s first domestically built submarine prototype, was launched on Sept. 28 last year.
It began its HAT a month later, and has been undertaking the final stage since Feb. 27.

Final delivery is expected in November next year.
Submarine systems are highly specialized and complex, Navy Chief of Staff Vice Admiral Chiu Chun-jung (邱俊榮) told a routine Ministry of National Defense news conference this morning.
The HAT is about 50 to 60 percent complete, and has identified more than 10 items in need of improvement, “not the 70 that has been reported,” he said.
Sea acceptance tests would be scheduled once all requirements are met, including floating, submersion and deep water testing, he said.
Chiu confirmed that the submarine was on track for delivery in November next year and acceptance by the navy the month after.
Asked whether the military would build submarine pens, Chiu said that not many cave-like bunkers for submarines exist around the world.
Submarine operations are complex and focus on surprise attacks and concealment, he said.
As the Taiwan Strait is a relatively small area of engagement, the nation’s submarines would be decentralized and join with other maritime forces as needed, he added, declining to disclose operational details.
Taipei has once again made it to the top 100 in Oxford Economics’ Global Cities Index 2025 report, moving up five places from last year to 60. The annual index, which was published last month, evaluated 1,000 of the most populated metropolises based on five indices — economics, human capital, quality of life, environment and governance. New York maintained its top spot this year, placing first in the economics index thanks to the strength of its vibrant financial industry and economic stability. Taipei ranked 263rd in economics, 44th in human capital, 15th in quality of life, 284th for environment and 75th in governance,
The Sports Administration yesterday demanded an apology from the national table tennis association for barring 17-year-old Yeh Yi-tian (葉伊恬) from competing in the upcoming World Table Tennis (WTT) United States Smash tournament in Las Vegas this July. The sports agency said in a statement that the Chinese Taipei Table Tennis Association (CTTTA) must explain to the public why it withdrew Yeh from the WTT tournament in Las Vegas. The sports agency said it contacted the association to express its disapproval of the decision-making process after receiving a complaint from Yeh’s coach, Chuang
Control Yuan Secretary-General Lee Chun-yi (李俊俋) tendered his resignation last night, admitting that he had misused a government vehicle, as reported by media. His resignation was immediately accepted by the Control Yuan. In a statement explaining why he had resigned, Lee apologized for using a Control Yuan vehicle to transport his dog to a pet grooming salon on May 20. The issue first came to light late last month, when TVBS News reported that Lee had instructed his driver to take the dog to the salon. The news channel broadcast photos that it said were taken by an unnamed whistle-blower, which purportedly showed the
A former officer in China’s People’s Liberation Army (PLA) who witnessed the aftermath of the 1989 Tiananmen Square massacre has warned that Taiwan could face a similar fate if China attempts to unify the country by force. Li Xiaoming (李曉明), who was deployed to Beijing as a junior officer during the crackdown, said Taiwanese people should study the massacre carefully, because it offers a glimpse of what Beijing is willing to do to suppress dissent. “What happened in Tiananmen Square could happen in Taiwan too,” Li told CNA in a May 22 interview, ahead of the massacre’s 36th anniversary. “If Taiwanese students or
