While several local news outlets are mentioning the ceremony took place this morning at the CSBC shipyard in Kaohsiung, pictures of the event are yet to be released. Pictures may never be released because of the high level of secrecy and strategic nature of the IDS project.
Local media LTN reported that the shipyard gave the first IDS the factory number “1168”. Pronunciation of 168 in mandarin Chinese, is similar to 一路發 (making money all the way), the number is believed to be a lucky number in Taiwan.
Construction work on IDS started almost exactly one year ago in presence of President Tsai Ing-wen. The Taiwanese President did not attend the keel laying ceremony.
ROC Navy Commander Liu Chi-bin said today during the keel laying ceremony:
The project team is paying attention to construction safety and confidentiality throughout the process. I hope the first submarine will be completed on schedule to meet the expectations and support of the president and the people.
As we previously reported, the IDS will be armed with MK-48 Mod 6 Advanced Technology heavyweight torpedoes, UGM-84L sub-launched Harpoon Block II missiles, and other combat and digital sonar systems provided by US suppliers Lockheed Martin and Raytheon, Taiwanese naval officials said. Senior military officers told local media that the submarine will be fitted with ‘high-efficiency batteries developed and produced by domestic manufacturers” instead of an Air Independent Propulsion (AIP) system. This most likely refers to the use of Lithium Ion battery technology.
About Taiwan’s Indigenous Defense Submarine (IDS) Project
The ROC Navy and local shipyard China Shipbuilding Corporation (CSBC) signed a construction contract for a prototype submarine as part of the Indigenous Defense Submarine project (IDS) in May 2019. According to the initial schedule, the design of the prototype will be completed by the end of the year and its delivery to the ROC Navy is expected for 2025.
According to Covert Shores, the new design builds on the Hai Lung class, keeping a similar form but deviating notably by X-form rudders and a more contemporary sail. This implies that it will be double-hulled with a relatively conventional internal arrangement.
The new design appears to be based on the Dutch design heritage, which makes sense as Taiwan operates two Dutch designed boats. The fitting of new battery technologies, probably lithium-ion, will put the design into the upper tier of non-nuclear submarines. Other countries are also building submarines with these battery technologies, notably Japan, South Korea and Italy. Navies have been slow to adopt lithium-ion batteries for submarines due to safety concerns, They are too prone to fire. Countries which are pushing ahead with this technology however believe that they have solved this problem. For Taiwan, coming in fresh, this may be a fresh challenge however.

Taiwan Lays Keel of New IDS Submarine for ROC Navy - Naval News
Taiwan' shipbuilder China Shipbuilding Corporation (CSBC) today laid the keel of the first submarine known as Indigenous Defense Submarine (IDS). The move aims at renewing the submarine forces of the Republic of China (ROC) Navy while developing a domestic capability to produce submarines.
