 For more than two decades, Taiwan tried to buy a fleet of modern conventional submarines to fend off an existential threat – invasion by China. There were no takers.

The United States, Taiwan’s main ally, has a nuclear-powered fleet and hadn’t built diesel-powered subs in decades. Other nations balked, fearful of angering Beijing.

Taipei has stealthily sourced technology, components and talent from at least seven nations to help it build an underwater fleet with the potential to exact a heavy toll on any Chinese attack, a Reuters investigation has found.

Taipei’s chief foreign weapons supplier, the United States, has provided key technology, including combat-system components and sonars. But assistance is coming from far beyond America.

Defense companies from the United Kingdom, which like America operates a fleet of nuclear-powered ballistic missile and attack submarines, have provided crucial support.

A veteran of Britain’s Royal Navy submarine fleet, retired Commodore Ian McGhie, was a key figure in the drive to recruit submarine expertise, according to a person familiar with his role. McGhie helped a Gibraltar-based company hire engineers including former Royal Navy sailors, the person said.

Britain also has approved multiple export licences in the past three years for UK companies to supply submarine components, technology or software to Taiwan, according to information from the Department for International Trade obtained via a Freedom of Information request. The value of submarine technologies approved for export from the UK to Taiwan has grown exponentially in recent years, government data analyzed by Reuters shows.

Taipei also succeeded in hiring engineers, technicians and former naval officers from at least five other countries: Australia, South Korea, India, Spain and Canada. Based at a shipyard in the port city of Kaohsiung, the experts have advised the Taiwanese navy and state-backed shipbuilder CSBC Corporation Taiwan, the company building the new submarines.

Taiwan scoured the globe for this submarine engineering expertise, Rupert Hammond-Chambers, the president of the US-Taiwan Business Council, told Reuters.

“It’s a jigsaw,” Hammond-Chambers said. Taiwan had to search the international market for technology and components it was unable to source domestically. So, he said, it “cut down the pie to smaller pieces” to figure out which work required foreign assistance, such as help in completing the design of the submarines.

The Taiwanese project, which officially began in 2017, is formally known as the Indigenous Defense Submarine program. It is codenamed Hai Chang, which means “Sea Prosperity” in Chinese. Shipbuilder CSBC began construction last year and is aiming to deliver the first of the planned eight vessels by 2025, according to government statements. The value of the project is estimated at up to $16 billion, according to the London-based International Institute for Strategic Studies.

Informed about the findings of this article, a spokesperson for China’s foreign ministry said the Taiwanese “authorities are colluding with external forces” on the program. The countries concerned, the spokesperson said in a written statement, should refrain from participating in the submarine effort, “stop military ties with Taiwan and stop supporting the ‘Taiwan independence’ secessionist forces.”

These countries are “playing with fire, and those who play with fire will get burned themselves,” the spokesperson said.

Taiwan’s defense ministry said the new submarines are crucial for “the national defense forces’ asymmetric warfare,” a reference to waging war against a superior military foe. It added that various challenges facing the program have been “eliminated” and it is being “implemented according to plan.”

CSBC declined to comment.


Some details of the sub project, including the involvement of a small number of foreign engineers and some tenders for equipment and expertise, have been previously reported by Reuters and others. This report provides the most detailed account yet of the program and the extent of foreign assistance Taiwan is receiving. It is based on reporting in 11 countries and interviews with more than 80 people, including current and former officials, diplomats, former submariners and defense industry sources. Reporters also analyzed corporate filings and thousands of social media postings.

Two people in Taiwan with direct knowledge of the program said project leaders devised a low-profile strategy to limit Beijing’s ability to pressure foreign governments and companies not to work with Taipei. The Taiwanese team approached foreign companies directly, rather than first requesting approval from national governments, the two people said. With orders in hand, the foreign companies then applied for export permits from their governments.

Export approvals have now been secured for all the key components, according to the two people and public statements by Taiwan officials. Many of these parts are related to the combat system, the two people said.

To minimize such setbacks, the Taiwan team secured access to two or three sources of many important technologies in the event one of the suppliers pulled out, the two people said.

Taiwan’s success in securing expertise and technology reflects the West’s mounting concern over China’s expanding military might and the pressure Beijing is exerting on the island, foreign diplomats say. In September, Britain and the United States struck a deal with Australia to help Canberra build nuclear-powered subs as America and its allies respond to

The submarine aid is a breakthrough for isolated Taipei, which doesn’t have official diplomatic recognition from the nations that approved export permits for the project. “Taiwan isn’t really that lonely,” said one of the people in Taiwan with knowledge of the program. “Given all the export permits we managed to get, we know that many countries are helping.”

Asked about British help on the project, a UK government spokesperson said that Britain’s “longstanding policy on Taiwan has not changed: we have no diplomatic relations with Taiwan but a strong, unofficial relationship, based on dynamic commercial, educational and cultural ties.”

“The United States will continue to make available to Taiwan the defense articles and services necessary to enable Taiwan to maintain a sufficient self-defense capability,” a U.S. Department of State spokesperson said in response to questions about the program. “Doing so increases stability both across the Taiwan Strait and within the region.”

Beijing insists Taiwan is part of China and has called repeatedly for peaceful unification, but refuses to rule out using force to bring the island under its control. President Tsai Ing-wen says Taiwan is an independent country called the Republic of China, its official name, and has vowed to defend its freedom and democracy. As Chinese shipyards churn out the warships that would be required for an invasion, a fleet of modern submarines would significantly boost Taiwan’s firepower.


Former military chief Huang, now senior adviser on the National Security Council, gave updates to lawmakers on the project that were treated with extreme secrecy. Lawmakers had to sign a confidentiality agreement, said a person who attended the briefings. In some of the meetings, held over the past few years, navy officers brought in a model of the submarine in a cardboard box before it was revealed to the lawmakers. The model looked different each time, the person said, as the designs evolved.

In a meeting late last year, the navy presented documentation of export permits issued by foreign governments for lawmakers to review. The names of the companies were coded, and lawmakers had to consult a manual to see which firms were assisting in the program, the person said. Each time a lawmaker used the manual, their name and the page numbers they viewed were recorded.

Obstacles remain. Building a submarine from scratch is expensive and technically challenging. Taiwan has also had to contend with the refusal of established conventional submarine builders to provide a design or other assistance.

The Netherlands, for instance, has agreed to maintain the two existing Sea Dragons. But the country is not engaged in Taiwan’s new sub. Asked why, the Dutch foreign ministry said that under the 1984 agreement with Beijing, the government wouldn’t approve any new export permits for military equipment to the island.

Tokyo, one of America’s closest allies, has also been reticent to get involved. Japan operates one of the world’s most advanced conventional submarine fleets. The idea of helping Taiwan was informally discussed in Japan but was dropped out of concern over how China might react, according to two senior defense ministry sources in Tokyo.

One reason for Japan’s hesitancy is fear of the economic consequences of offending Beijing, said retired Vice Admiral Yoji Koda, a former fleet commander of the Japanese Maritime Self-Defense Force. Japanese companies that would stand to lose business in China for helping Taiwan are a powerful lobby, Koda said.

Japan’s defense ministry declined to comment.

To keep its suppliers on board, Taiwan has proceeded quietly. Some hints of the international support have trickled out, however.

In November last year, CSBC’s chairman, Cheng Wen-lon, confirmed that foreigners had worked alongside the shipbuilder’s in-house staff to draft the blueprints. “Our staff drew the blueprint by themselves, of course, with assistance from foreign technical personnel, but we did the main body ourselves,” he said in response to questions from Taiwanese lawmakers. Cheng told legislators he was not allowed to reveal where the foreign technical assistance was coming from, however.

A little-known company that was incorporated in the British Overseas Territory of Gibraltar in 2013 provided a key talent pipeline. The company, Gavron Limited, headed by two Israelis, won a contract to provide technical advice to CSBC. The contract was for about T$600 million ($20 million), according to a 2018 defense ministry press release. Corporate filings list the two directors of Gavron as Gil Yossef Cooper and Arie Beizer.

Beyond the news that it secured a contract and has recruited some engineers for the project, little has been disclosed about Gavron’s role. A Gavron manager told Reuters he couldn’t answer questions without first getting permission from the client. The manager declined to make Cooper and Beizer available for interviews.

On its website, Gavron says it offers “decades of experience from consultants such as nuclear submariners … as well as others with niche technical skills.” The company also says that “many” of its consultants were career submariners in the British Royal Navy.

This included McGhie, the former senior Royal Navy submariner who recruited engineers to work on the Taiwan project. A 2017 job ad for a submarine engineer for Gavron in Taiwan was posted on an online European job platform. It listed McGhie as the contact person.

Work would include “pressure hull and major bulkhead design review,” the ad said. Both are crucial elements: The pressure hull, made of specialized steel, is the structure that keeps the submarine watertight when it submerges. It must withstand enormous forces. The bulkheads are interior structures that divide the submarine into sections to reinforce the pressure hull and allow flooded compartments to be sealed in an emergency.

Contacted by Reuters for comment, McGhie said he would need to seek permission from Gavron to talk about the project because of the sensitivity of the client and his own contractual obligations. He didn’t specifically mention Taiwan. In a follow-up email, McGhie said there were “some inconsistencies and minor inaccuracies” in this account of his and Gavron’s role, but he did not elaborate. In his LinkedIn profile, he says he assisted a Gibraltar company in securing “a multi-million pound, complex technical service to a Client in the heavy industry sector in the Far East.”

McGhie was the commander of British forces in Gibraltar until 2016, according to a UK government web page. His LinkedIn profile notes that he spent 32 years in the military and was part of a team that “devised, negotiated and delivered” the UK’s first National Cyber Security Programme, a £650 million project, while he was at the Office of Cyber Security in Britain’s Cabinet Office.


Reuters found at least 12 foreign engineers who said in interviews or on social media that they had worked on the submarine program or worked for Gavron in Taiwan.

These recruits – a mix of young and veteran submarine experts – had experience working on advanced submarine programs. These included the S-80 built by Spanish state-owned shipbuilder Navantia and Britain’s nuclear-powered Astute-class attack subs built by BAE Systems, according to the recruits’ social media profiles.

In a 2017 article posted on his university’s website, Juan Herrero Valero, a Spanish naval architect, said he started working that year for a British company in Kaohsiung on the Taiwan program. He said he was recruited for the project after being approached via LinkedIn. “I was really surprised because I’m very young,” the engineer said in the article. He noted that he was in Taiwan working with far more experienced engineers. “But the consulting team has trusted me.” He declined to speak to Reuters.

Last month, the United States disclosed with little fanfare that it would approve the sale of key technology for the project. The word came in a State Department letter to Congress dated Jan. 5, which was posted in October in the Federal Register, the official publication of U.S. government notices. Washington was prepared to license transfers of technical data and services to Taiwan, Italy and the UK valued at $50 million or more to support Taiwan’s submarine project, the letter said. The technology would “support the integration, installation, operation, training, testing, maintenance, and repair of systems” supporting the program, the letter said.

Washington has kept a lid on most details, however, including which U.S. companies are involved. According to two sources in Taiwan, Lockheed Martin Corp is providing the subs’ combat system, which integrates and displays sonar and other sensor data to allow commanders to engage targets. Raytheon Technologies Corp is supplying the sonars, the sources said.

In 2018, Lockheed posted a recruitment advertisement on JobSearcher.com, an online job site, for a deputy program manager for work on Taiwan’s existing Sea Dragon submarines and the design phase of the new indigenous sub program. Candidates must have “foreign language skills in Mandarin Chinese,” the posting said. Earlier this year, Lockheed advertised on another online jobs site for a combat systems engineer for work on the Sea Dragon and the new sub.

Lockheed and Raytheon declined to comment for this story.

The aid to Taiwan is in line with longstanding U.S. policy. Since Washington switched diplomatic recognition from Taipei to Beijing in 1979, U.S. administrations have been required by law to provide Taiwan with the means to defend itself.

British companies also are playing a key role. In response to a freedom of information request, the UK’s Department for International Trade disclosed that 28 “applicants,” or corporate entities, had been granted licenses in the past three years to export submarine components, technology or software to Taiwan. The department didn’t specifically mention the submarine program.

The list included QinetiQ Ltd, a high-tech defense company. Three people with knowledge of the matter confirmed QinetiQ was involved in Taiwan’s program. One said the company provided advice on underwater safety management. QinetiQ declined to comment.

A Canadian subsidiary of Britain’s BMT Group Ltd has also been involved. BMT is a contractor for the UK nuclear submarine fleet. BMT Canada Ltd, the subsidiary, was hired to provide consulting and engineering advice, said four people with knowledge of the deal. This included reviewing plans drawn up by CSBC, said one of the people.

BMT Group declined to comment. Global Affairs Canada had no comment on BMT Canada’s involvement. “Canada does not maintain military-to-military or defense relations with Taiwan,” the foreign ministry said in a statement.

The value of submarine technologies and equipment approved for export from the UK to Taiwan has grown dramatically, a Reuters analysis of government data shows.

Between 2011 and 2017, Britain approved export licenses for the sale of at least £323,549 ($432,000) worth of sub equipment to Taiwan. That jumped to at least £158 million ($211 million) between 2018 and March this year. The equipment included test models and software. The UK data did not specify if the exports were for the new sub program.

As Taiwan pushes to complete the first vessel by 2025, the two people with knowledge of the program said their main concerns are delays to the import of equipment because of COVID-19 and possible pressure on suppliers by China.
