Russia’s invasion of Ukraine has been going on for nearly a year and a half. At the end of last year Ukraine started building the world’s first “naval fleet of drones” to counter Russia’s Black Sea fleet, news reports said. One of Ukraine’s maritime drones — an uncrewed surface vessel (USV) that resembles a speedboat — is 5.5m long and weighs one tonne. It has an operational radius of up to 400km and can operate autonomously for up to 60 hours. It can carry a combat load of up to 200kg and has a maximum speed of 80kph. The USV’s main functions include long-range maritime reconnaissance and coastal surveillance, escorting and supporting Ukraine’s conventional fleet and countering amphibious operations, among others. This Ukrainian-developed USV is believed to be the weapon that badly damaged the Kerch Bridge in Crimea on July 17, effectively blocking Russia’s logistical supply line, and had attacked the Crimean Black Sea port of Sevastopol the previous day.
Taiwan would do well to learn from this experience. To be ready for a war across the Taiwan Strait, the nation should develop a sea-drone fleet that is maneuverable, fast, cheap and effective. In recent years there have been several incidents of Chinese illegally crossing over to Taiwan on simple rubber dinghies. As well as favorable sea conditions and good luck, another reason they managed to reach Taiwanese territory is that a dinghy’s low profile on the sea surface makes it hard to detect using electronic devices. For the same reason, USVs have a “stealth” function. Despite their small size, they can be used to hit ships of the People’s Liberation Army Navy as they try to cross the Taiwan Strait, thus giving Taiwan a chance to win decisively outside its own territory.
Taiwan also needs to develop a system that can launch sea-to-air or sea-to-ground missiles from USVs. If China were to invade Taiwan, the first attack waves would destroy more than half of Taiwan’s military airfields, warships, naval harbors and missile bases, as well as a large number of the military personnel stationed at those sites. In such a scenario, easily concealed sea drones and their operators stationed in bunkers might well play a role in turning the tide of the war.

Concerns that the US might abandon Taiwan are often overstated. While US President Donald Trump’s handling of Ukraine raised unease in Taiwan, it is crucial to recognize that Taiwan is not Ukraine. Under Trump, the US views Ukraine largely as a European problem, whereas the Indo-Pacific region remains its primary geopolitical focus. Taipei holds immense strategic value for Washington and is unlikely to be treated as a bargaining chip in US-China relations. Trump’s vision of “making America great again” would be directly undermined by any move to abandon Taiwan. Despite the rhetoric of “America First,” the Trump administration understands the necessity of
US President Donald Trump’s challenge to domestic American economic-political priorities, and abroad to the global balance of power, are not a threat to the security of Taiwan. Trump’s success can go far to contain the real threat — the Chinese Communist Party’s (CCP) surge to hegemony — while offering expanded defensive opportunities for Taiwan. In a stunning affirmation of the CCP policy of “forceful reunification,” an obscene euphemism for the invasion of Taiwan and the destruction of its democracy, on March 13, 2024, the People’s Liberation Army’s (PLA) used Chinese social media platforms to show the first-time linkage of three new
If you had a vision of the future where China did not dominate the global car industry, you can kiss those dreams goodbye. That is because US President Donald Trump’s promised 25 percent tariff on auto imports takes an ax to the only bits of the emerging electric vehicle (EV) supply chain that are not already dominated by Beijing. The biggest losers when the levies take effect this week would be Japan and South Korea. They account for one-third of the cars imported into the US, and as much as two-thirds of those imported from outside North America. (Mexico and Canada, while
The military is conducting its annual Han Kuang exercises in phases. The minister of national defense recently said that this year’s scenarios would simulate defending the nation against possible actions the Chinese People’s Liberation Army (PLA) might take in an invasion of Taiwan, making the threat of a speculated Chinese invasion in 2027 a heated agenda item again. That year, also referred to as the “Davidson window,” is named after then-US Indo-Pacific Command Admiral Philip Davidson, who in 2021 warned that Chinese President Xi Jinping (習近平) had instructed the PLA to be ready to invade Taiwan by 2027.
