Taking lessons from Ukraine, Taiwan eyes sea drones to counter China

WUSHI, Taiwan, June 13 (Reuters) - Just off the small Taiwan fishing port of Wushi on its Pacific coast, a Taiwanese company is testing what could eventually be a powerful but unglamorous new weapon in the island'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 United States, Taiwan has been working to transform its armed forces to be able to wage "asymmetric warfare", using mobile, smaller and often cheaper weapons which still pack a targeted punch, like sea drones.
"Uncrewed boats or vehicles have played a very significant role in the Ukraine war," Chen Kuan-ting, a lawmaker for Taiwan's ruling Democratic Progressive Party (DPP) who sits on parliament's foreign affairs and defence committee, told Reuters.
"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.
Taiwan's defence ministry's research and development arm, the National Chung-Shan Institute of Science and Technology, has termed the sea drone plan the "Swift and Sudden" project, which so far has a modest budget of around T$800 million ($26.77 million).
Defence Minister Wellington Koo said on Wednesday 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.
William Chen, chairman of the Thunder Tiger company, told Reuters last week on a boat off Wushi while viewing a test of their SeaShark 800 sea drone, which can carry 1,200 kg (2,600 lbs) of explosives and travel up to 500 km (310 miles), 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 added.
Next week, Thunder Tiger will be among 12 Taiwanese and foreign companies joining an exhibition just down the coast from Wushi arranged by the defence ministry to showcase unmanned surface vehicles that may end up being added to Taiwan's arsenal.
Other companies taking part, according to the ministry, include Taiwan navy contractor Lungteh Shipbuilding (6753.TW), opens new tab and U.S. military shipbuilder Huntington Ingalls Industries (HII.N), opens new tab.
"Drones is 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 Rupert Hammond-Chambers, president of the U.S.-Taiwan Business Council, who is leading a U.S. defence industry delegation to Taiwan this week, including drone makers.
China views democratically governed Taiwan as its own territory and has ramped up its military pressure over the past five years, including staging half a dozen rounds of war games. Taiwan's government rejects Beijing's sovereignty claims.
Since Russia invaded Ukraine in 2022, Taiwan has been studying how Ukraine 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, though 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, a drone expert and executive director of Taiwan security think tank TTRDA, said Taiwan can 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.
