Submarine sales to Taiwan are “highly improbable,” a new commentary published by the US Council on Foreign Relations says.
“Transferring submarine technology to the island will take too long and cost the Taiwanese military far more than what it can afford,” council research associate Lauren Dickey said.
She said that the costs the US would incur to resurrect small numbers of diesel-powered submarines for Taipei would yield few benefits for the US military.
Dickey said that US submarine help to Taiwan would “tap into state of the art technology used in US nuclear-powered submarines” and that is not something the Pentagon would be eager to share with others.
“As Taiwanese military officials have an unfortunate history of passing classified military information into the hands of the People’s Liberation Army, Washington should remain cautious in transferring any sensitive technology or capabilities to Taiwan,” Dickey said.
She said that Germany, Japan and the Netherlands all produce small, diesel-electric submarines that would meet Taiwan’s needs, but that what holds these countries back from selling to Taiwan is the fear of economic or political fallout from Beijing.
“China has demonstrated time and time again an ability to impose political costs and threaten those that sell weapons to Taiwan,” Dickey said.
She also said that any submarines acquired by Taiwan may actually do more harm than good due to their vulnerabilities to existing Chinese weapons.
“Simply put, diesel submarines are not the effective defensive capability the island wants or needs,” Dickey said.
Rather, she said, Taiwan should strengthen its antisubmarine warfare capabilities and add to its fleet of 12 P-3 Orion antisubmarine aircraft, replacing its antiquated S-2 Tracker aircraft.
Dickey also recommended more land-based anti-ship missiles and high-speed multifunctional fast attack craft similar to the Type-022 Houbei class.
“In the case a more conservative government emerges after mid-term elections in November, or perhaps more importantly, a pro-independence Democratic Progressive Party (DPP) government steps in to lead Taiwan in 2016, the need to re-evaluate Taiwan’s defense requests will persist, but for now, as Washington’s rebalance to Asia plays out, there is neither time nor money requisite to help the island develop its nascent submarine program,” she said.
Senior fellow on Asian military affairs at the International Assessment and Strategy Center (IASC) Richard Fisher strongly disagreed with a number of Dickey’s arguments.
He said the US was not limited to US nuclear submarine technology.
“The US developed the Barbel Class conventional submarine in the late 1950s and it was so advanced that it became the basis for Japan’s early classes of submarines. Washington could purchase Japan’s advanced version of the Barbel on behalf of Taiwan,” Fisher said.
Fisher said the US was the principal subcontractor for Australia’s Collins-class submarines, supplying combat systems. Washington could assist Taiwan’s current submarine plans in the same way, he said.
Turning to Dickey’s claims that submarines were too expensive for Taiwan, he said Taipei had settled on a small, but still tactically useful, though much less expensive submarine design.
“Submarines are very expensive, but the deterrent value they offer against China is well worth the price,” Fisher said.
He said that every weapon sold to Taiwan, or most other US allies, suffered under the threat of espionage.
“The US probably takes precautions that it would rather not disclose,” he said. “Americans have never shied away from selling arms and offering assistance, and we should not start when it comes to selling submarine technology to Taiwan.”
He said that any weapon that could defeat a Chinese invasion was what Taiwan needed right now.
“Submarines can hide, wait and sink the scores of large ships filled with the troops and tanks that would be used to invade Taiwan,” he said. “Missile emplacements and other elements can be attacked by Chinese missile and air power. They have to work much much harder to find Taiwan’s submarines.”
Taipei has once again made it to the top 100 in Oxford Economics’ Global Cities Index 2025 report, moving up five places from last year to 60. The annual index, which was published last month, evaluated 1,000 of the most populated metropolises based on five indices — economics, human capital, quality of life, environment and governance. New York maintained its top spot this year, placing first in the economics index thanks to the strength of its vibrant financial industry and economic stability. Taipei ranked 263rd in economics, 44th in human capital, 15th in quality of life, 284th for environment and 75th in governance,
The Sports Administration yesterday demanded an apology from the national table tennis association for barring 17-year-old Yeh Yi-tian (葉伊恬) from competing in the upcoming World Table Tennis (WTT) United States Smash tournament in Las Vegas this July. The sports agency said in a statement that the Chinese Taipei Table Tennis Association (CTTTA) must explain to the public why it withdrew Yeh from the WTT tournament in Las Vegas. The sports agency said it contacted the association to express its disapproval of the decision-making process after receiving a complaint from Yeh’s coach, Chuang
Control Yuan Secretary-General Lee Chun-yi (李俊俋) tendered his resignation last night, admitting that he had misused a government vehicle, as reported by media. His resignation was immediately accepted by the Control Yuan. In a statement explaining why he had resigned, Lee apologized for using a Control Yuan vehicle to transport his dog to a pet grooming salon on May 20. The issue first came to light late last month, when TVBS News reported that Lee had instructed his driver to take the dog to the salon. The news channel broadcast photos that it said were taken by an unnamed whistle-blower, which purportedly showed the
A former officer in China’s People’s Liberation Army (PLA) who witnessed the aftermath of the 1989 Tiananmen Square massacre has warned that Taiwan could face a similar fate if China attempts to unify the country by force. Li Xiaoming (李曉明), who was deployed to Beijing as a junior officer during the crackdown, said Taiwanese people should study the massacre carefully, because it offers a glimpse of what Beijing is willing to do to suppress dissent. “What happened in Tiananmen Square could happen in Taiwan too,” Li told CNA in a May 22 interview, ahead of the massacre’s 36th anniversary. “If Taiwanese students or
