Just off the small fishing port of Wushi (烏石) in Yilan County, a Taiwanese company is testing what could eventually be a powerful, but unglamorous new weapon in the nation’s military arsenal — sea drones.
Used to great effect by Ukraine in the Black Sea against Russia, Taiwan is learning lessons on how it could use sea drones as an effective and low-cost way to fend off any possible Chinese invasion.
These drones are uncrewed, remotely controlled small vessels that are packed with explosives and can be guided toward ships or potentially even attack targets in the air.

Pushed by the US, Taiwan has been working to transform its armed forces to be able to wage “asymmetric warfare” using mobile, smaller and often cheaper weapons that still pack a targeted punch, like sea drones.
“Uncrewed boats or vehicles have played a very significant role in the Ukraine war,” said Democratic Progressive Party (DPP) Legislator Chen Kuan-ting (陳冠廷), who sits on the Foreign Affairs and National Defense Committee.
“Uncrewed vehicles, whether they are boats or underwater vehicles, can effectively deter China because Taiwan is not the attacking side, we are the defending side,” he said.
Chungshan Institute of Science and Technology — the research and development arm of the Ministry of National Defense — has termed the sea drone plan the “Swift and Sudden” project, which has a modest budget of about NT$800 million (US$ 26.97 million).
Minister of National Defense Wellington Koo (顧立雄) on Wednesday said that sea drones would be included in an additional spending package to be unveiled later this year.
Details of that special budget have yet to be announced.
Thunder Tiger Corp chairman William Chen (陳冠如) told Reuters last week on a boat off Wushi while viewing a test of the company’s SeaShark 800 sea drone —which can carry 1,200kg of explosives and travel up to 500km — that these new weapons present an element of surprise for China.
“We can create uncertainty. We can fill the Taiwan Strait with danger and risks. No one knows where these dangers could surface,” Chen said.
Next week, Thunder Tiger is to join 11 Taiwanese and foreign companies in an exhibition just down the coast from Wushi arranged by the defense ministry to showcase uncrewed surface vehicles that might end up being added to Taiwan’s arsenal.
Other companies taking part include Taiwanese navy contractor Lungteh Shipbuilding and US military shipbuilder Huntington Ingalls Industries, the ministry said.
“Drones are a top priority for both the United States and Taiwan. Obviously the conflict in Ukraine is focusing minds on what the next generation of warfare will look like,” said US-Taiwan Business Council president Rupert Hammond-Chambers, who is leading a US defense industry delegation to Taiwan this week, including drone makers.
Since Russia invaded Ukraine in 2022, Taiwan has been studying how Kyiv has deployed drones to successfully offset Russia’s advantage on the battlefield and has enlisted commercial drone companies, including Thunder Tiger, to help.
Ukraine has deployed sea drones not only to attack ships in Russia’s Black Sea fleet, but also to shoot down aircraft.
Taiwan’s navy is dwarfed by that of China with its aircraft carriers and ballistic missile submarines, although the country lacks recent combat experience.
China’s last successful large-scale amphibious assault was in 1950, when it seized Hainan Island at the tail end of the Chinese Civil War, with troops ferried across on junks.
Peter Chen (陳柏宏), a drone expert and executive director of Taiwan security think tank Taiwan Military and Police Tactics Research and Development Association, said that Taiwan could undoubtedly make world-class sea drones.
“But when it comes to the application, how to turn them into top-notch weapons, it is not the responsibility of private companies. The views of government and the military on how to properly integrate the weapons into the battle strategy, that needs more thinking,” he said.
Eight Chinese naval vessels and 24 military aircraft were detected crossing the median line of the Taiwan Strait between 6am yesterday and 6am today, the Ministry of National Defense said this morning. The aircraft entered Taiwan’s northern, central, southwestern and eastern air defense identification zones, the ministry said. The armed forces responded with mission aircraft, naval vessels and shore-based missile systems to closely monitor the situation, it added. Eight naval vessels, one official ship and 36 aircraft sorties were spotted in total, the ministry said.
The Ministry of Foreign Affairs (MOFA) today said that if South Korea does not reply appropriately to its request to correct Taiwan’s name on its e-Arrival card system before March 31, it would take corresponding measures to alter how South Korea is labeled on the online Taiwan Arrival Card system. South Korea’s e-Arrival card system lists Taiwan as “China (Taiwan)” in the “point of departure” and “next destination” fields. The ministry said that it changed the nationality for South Koreans on Taiwan’s Alien Resident Certificates from “Korea” to “South Korea” on March 1, in a gesture of goodwill and based on the
Taiwanese officials were shown the first of 66 F-16V fighter jets purchased by Taiwan from the United States, the Ministry of National Defense said yesterday, adding the aircraft has completed an initial flight test and is expected to be delivered later this year. A delegation led by Deputy Minister of National Defense Hsu Szu-chien (徐斯儉) visited Lockheed Martin’s F-16 C/D Block 70 (also known as F-16V) assembly line in South Carolina on March 16 to view the aircraft. The jet will undergo a final acceptance flight in the US before being delivered to Taiwan, the
The New Taipei Metro's Sanyin Line and the eastern extension of the Taipei Metro's Tamsui-Xinyi Line (Red Line) are scheduled to begin operations in June, the National Development Council said today. The Red Line, which terminates at Xiangshan Station, would be connected by the 1.4km extension to a new eastern terminal, Guangci/Fengtian Temple Station, while the Sanyin Line would link New Taipei City's Tucheng and Yingge stations via Sanxia District (三峽). The council gave the updates at a council meeting reviewing progress on public construction projects for this year. Taiwan's annual public infrastructure budget would remain at NT$800 billion (US$25.08 billion), with NT$97.3
