The Indigenous Defense Submarine (IDS) prototype is expected to undergo a harbor acceptance test in September, a sea acceptance test in February next year and, if it passes, be delivered to the navy in the first half of 2025 instead of November 2025, defense officials said yesterday.
The goal of the IDS program is to create a fleet of nine to 11 domestic diesel-electric submarines that would defend the waters around Taiwan, the officials said, speaking on condition of anonymity.
The IDS prototype features a partial double-hull design consisting of six pressurized compartments and a conning tower, which have been completed, certified and are undergoing encapsulation, they said.

The boat would be 70m long, 8m wide and 18m high, including the conning tower, and have a displacement of 2,500 tonnes to 3,000 tonnes, the officials said.
It would have a pair of stabilizing fins on the sides of the conning tower and an X-shaped tail rudder, they added.
The submarine’s weapons would include 18 MK 48 Mod 6 heavyweight torpedoes and an undisclosed number of Harpoon missiles, they said.
There is reason to believe that due to improved program management the prototype could be completed ahead of schedule in early 2025 or before that, if system tests are successful, the officials said, adding that the project had generous time buffers.
Meanwhile, the Chungshan Institute of Science and Technology is poised to deliver the first of its upgraded operational systems for the navy’s aging Chien Lung-class submarines late this year, the officials said.
The navy is overhauling the operational systems used in the Hai Lung and Hai Hu Chien Lung-class submarines, as they are becoming obsolete, they said.
The NT$7.41 billion (US243.32 million) project aims to produce two systems for immediate use and one to be held in reserve, they said.
The project was to be completed next year, but the deadline has since been pushed forward three years due to difficulties in obtaining sensitive technology from overseas, the officials said.
The systems would be delivered one at a time from next year through 2026, with the certification of all systems to be completed at a dedicated testing facility in 2027, they said.
Research and development, systems integration and the sourcing of systems and components from foreign manufacturers is being managed by the institute under supervision of the navy, they added.
NATIONAL SECURITY THREAT: An official said that Guan Guan’s comments had gone beyond the threshold of free speech, as she advocated for the destruction of the ROC China-born media influencer Guan Guan’s (關關) residency permit has been revoked for repeatedly posting pro-China content that threatens national security, the National Immigration Agency said yesterday. Guan Guan has said many controversial things in her videos posted to Douyin (抖音), including “the red flag will soon be painted all over Taiwan” and “Taiwan is an inseparable part of China,” while expressing hope for expedited “reunification.” The agency received multiple reports alleging that Guan Guan had advocated for armed reunification last year. After investigating, the agency last month issued a notice requiring her to appear and account for her actions. Guan Guan appeared as required,
A strong cold air mass is expected to arrive tonight, bringing a change in weather and a drop in temperature, the Central Weather Administration (CWA) said. The coldest time would be early on Thursday morning, with temperatures in some areas dipping as low as 8°C, it said. Daytime highs yesterday were 22°C to 24°C in northern and eastern Taiwan, and about 25°C to 28°C in the central and southern regions, it said.

PAPERS, PLEASE: The gang exploited the high value of the passports, selling them at inflated prices to Chinese buyers, who would treat them as ‘invisibility cloaks’ The Yilan District Court has handed four members of a syndicate prison terms ranging from one year and two months to two years and two months for their involvement in a scheme to purchase Taiwanese passports and resell them abroad at a massive markup. A Chinese human smuggling syndicate purchased Taiwanese passports through local criminal networks, exploiting the passports’ visa-free travel privileges to turn a profit of more than 20 times the original price, the court said. Such criminal organizations enable people to impersonate Taiwanese when entering and exiting Taiwan and other countries, undermining social order and the credibility of the nation’s
‘SALAMI-SLICING’: Beijing’s ‘gray zone’ tactics around the Pratas Islands have been slowly intensifying, with the PLA testing Taiwan’s responses and limits, an expert said The Ministry of National Defense yesterday condemned an intrusion by a Chinese drone into the airspace of the Pratas Islands (Dongsha Islands, 東沙群島) as a serious disruption of regional peace. The ministry said it detected the Chinese surveillance and reconnaissance drone entering the southwestern parts of Taiwan’s air defense identification zone early yesterday, and it approached the Pratas Islands at 5:41am. The ministry said it immediately notified the garrison stationed in the area to enhance aerial surveillance and alert levels, and the drone was detected in the islands’ territorial airspace at 5:44am, maintaining an altitude outside the effective range of air-defense weaponry.
