US Security Partner Receives Submarine Boost Against China's Invasion Fleet
Taiwan-a key security partner of the United States-has begun sea trials of its first indigenous submarine following its unveiling nearly two years ago.
Newsweek has contacted the Chinese defense and foreign ministries for comment by email.
Communist China has long claimed Taiwan-a self-ruled, democratic island-as part of its territory, despite never having governed it. Beijing has vowed to achieve unification with the island, by force if necessary. U.S. officials believe Chinese leader Xi Jinping has instructed the People's Liberation Army (PLA) to be capable of taking Taiwan by 2027.
China has the world's largest navy by hull count, including numerous amphibious vessels capable of projecting air and land power from sea to shore during a potential island-landing campaign across the Taiwan Strait. In response to China's growing naval threat, Taiwan has been arming itself with anti-ship weapons-both U.S.-supplied and domestically developed.
Taiwan forms part of the First Island Chain under a U.S. containment strategy aimed at restricting China's naval activities in the Western Pacific during wartime. Meanwhile, the Taiwan Relations Act obligates Washington to provide the island with defensive weapons.
The Taiwanese navy submarineNarwhal, also known as Hai Kun, conducted "navigation tests" on Saturday and "floating navigation tests" on Tuesday in Kaohsiung Harbor, located in the southern part of the island, according to shipbuilder CSBC Corporation, Taiwan.
During the floating navigation tests, the submarine's systems-including propulsion, rudder, electricity, communication, and navigation-were evaluated, the shipbuilder added. These systems will be fine-tuned based on the test results prior to the next stage of sea trials.
The submarine, unveiled in September 2023, is scheduled to undergo three stages of trials at sea: floating navigation, shallow-water diving, and deep-water diving. The diving tests will require the submarine to be fully submerged at progressively greater depths and pressures.
The sea trials were originally scheduled for April, according to Taiwan's Central News Agency. It remains unclear whether the submarine will be able to complete the trials and be delivered before the November deadline set by the military.
According to a Pentagon report, the Taiwanese navy operates four attack submarines, while the PLA fields 47 conventionally powered and six nuclear-powered attack submarines, as well as six nuclear-powered ballistic missile submarines.
Of the four aging Taiwanese submarines, two were acquired from the Netherlands in the 1980s and two were former U.S. training submarines built during World War II.
The Chinese military has maintained a persistent presence around Taiwan with its naval and coast guard vessels, conducting exercises aimed at establishing a blockade around the island. Submarines would play a vital role in Taiwan's defense by countering any such blockade.
Chiu Chun-jung, Taiwanese Navy Chief of Staff, said in April: "April was the original goal [of commencing sea trials]...We are currently working on improvements and final calibrations to meet the requirements set for sea trials. That is our main goal."
Specialist outlet Naval News commented in September 2023: "Although a domestic submarine, most of the major mission-critical systems and subsystems of the [Narwhal] are provided by numerous foreign contractors with long and solid experience in the submarine industry."
Taiwan is expected to continue strengthening its defenses against a possible Chinese invasion from the sea, as China rapidly expands the size and capabilities of its naval fleet.

Oil prices jump 4% after U.S. strikes on Iran raise fears of supply disruption
Oil futures jumped 4% at the start of the first trading session since the U.S. launched direct attacks against Iran, casting further shadow over the supply outlook in the embattled oil-rich Middle Eastern region. U.S. crude oil rose $3.12, or 4.23%, to $76.96 per barrel, while global benchmark Brent jumped $3.27, or 4.25%, to $80.28 per barrel. U.S. President Donald Trump on Saturday surprised markets with the announcement that Washington had directly entered the Iran-Israel conflict, launching attacks against three Iranian nuclear sites in Fordo, Natanz and Isfahan. Iran's foreign minister said Sunday that the Islamic Republic reserves "all options" to defend its sovereignty and people, amid ongoing fire exchanges between Iran and Israel. U.S. Secretary of State Marco Rubio has warned Iran against attempting to close the Strait of Hormuz, a narrow waterway that is critical for the global oil market. Some 20 million barrels per day of crude, or 20% of global consumption, flowed through the strait in 2024, according to the Energy Information Administration. Iranian state media reported that Iran's parliament had backed closing of the strait, citing a senior lawmaker. However, the final decision to close the strait lies with Iran's national security council, according to the report. "It's economic suicide for them if they do it, and we retain options to deal with that," Rubio told Fox News. "It would hurt other countries' economies a lot worse than ours. It would be, I think, a massive escalation that would merit a response, not just by us, but from others." Iran produced 3.3 million bpd in May, according to OPEC's monthly oil market report released in June, which cites independent analyst sources. It exported 1.84 million bpd last month, with the vast majority sold to China, according to data from Kpler. Rubio called on China to use its influence to prevent Tehran from closing the strait. About half of China's waterborne crude oil imports comes from the Persian Gulf, according data to Kpler. "I encourage the Chinese government in Beijing to call them about that, because they heavily depend on the Straits of Hormuz for their oil," Rubio told Fox News. Investors are also watching the odds of a further destabilization of the Iranian regime as a result of U.S.-Israeli hostilities, given the example of the long-spanning impact that the 2011 NATO-led ousting of Muammar Gaddafi had on Libya's supplies. Tensions have likewise ramped up in neighboring Iraq, OPEC's second-largest producer, where pro-Tehran militia have previously threatened Washington, should it target Iran's supreme leader, Ayatollah Ali Khamenei. On Sunday, Iran's Revolutionary Guard warned that "the US bases in the region are not their strength but rather their greatest vulnerability" without specifying particular sites, according to Google-translated comments carried by Iranian news agency Fars. Fledgling, but revived diplomatic ties between former rivals Iran and Saudi Arabia could meanwhile diffuse the possibility of disruptions in the supply of the world's largest crude exporter. "The Kingdom of Saudi Arabia is following with deep concern the developments in the Islamic Republic of Iran, particularly the targeting of Iranian nuclear facilities by the United States of America," the Saudi foreign ministry said on Sunday. Riyadh, a close U.S. ally in the Middle East, has limited its involvement in the Iran-Israel offensives. Back in 2019 — four years before resuming diplomatic relations with Iran — Saudi Arabia's oil installation facilities at Abqaiq and Khurais sustained damage during attacks that were claimed by the Houthis, but for which Riyadh and the U.S. said Iran bore responsibility. Tehran denied involvement. At the resumption of Israeli-Iranian fire last week, the International Energy Agency's chief Fatih Birol said the institution was monitoring the developments and that "markets are well supplied today but we're ready to act if needed," with 1.2 billion barrels of emergency stocks on standby.

Dow futures slide 200 points as oil rises following U.S. bombing of Iran: Live updates
Traders work on the floor of the New York Stock Exchange (NYSE) in New York City on June 18, 2025. Timothy A. Clary | Afp | Getty Images Stock futures fell ahead of Monday's session after the United States entered Israel's war against Iran over the weekend by striking three nuclear sites, a move by President Donald Trump that raised oil prices and risked a bigger conflict in the Middle East. Futures tied to the Dow Jones Industrial Average fell by 159 points, or 0.4%. S&P 500 futures shed 0.4% and Nasdaq 100 futures lost 0.5%. The U.S. launched attacks Saturday at Iranian sites in Fordo, Isfahan and Natanz, surprising investors who were expecting more diplomacy to possibly take place after Trump said on Friday that he would make a decision to attack Iran "within the next two weeks," according to the White House. Oil prices have already spiked in recent weeks following the increased tensions in the Middle East. On Sunday night, U.S. crude oil futures rose another 3.8% to nearly $77 a barrel. "When you have conflict, you have an overreaction — a knee jerk reaction — which tends to be an exaggeration, that can last up to two to three weeks," said Jay Woods, chief global strategist at Freedom Capital Markets. "With Ukraine, the S&P 500 sold off 6% and oil spiked dramatically." Trump said in a Saturday evening speech from the White House after the attacks, that "there will be either peace, or there will be tragedy for Iran far greater than we have witnessed over the last eight days." Now traders braced for Iran's retaliation. The country could target U.S. personnel in nearby bases or close the Strait of Hormuz, which would majorly disrupt global oil flows. A prolonged blocking of the strait could boost oil prices above $100 per barrel. In a Sunday interview, with Fox News, U.S. Secretary of State Marco Rubio called for the Chinese government to step in and prevent Iran from closing the key trade route. China remains Iran's most important oil customer. "Now with the US fully engaged in the conflict, the baseline for oil prices has shifted to the mid $80s range per barrel entering stage two from one-side regional conflict to US managed conflict," said Ahmad Assiri of Pepperstone. "Even if Iran doesn't physically close the strait or attack oil tanks, the mere increase in probability from about 5% to around 15% will itself create a premium in crude prices." The S&P 500 lost 0.15% last week for its second negative week in a row. Despite this soft patch, the benchmark closed Friday about 3% from a record. The spike in oil prices and a greater war in the Middle East adds another threat to the stock market and the economy, already dealing with a rushed remaking of global trade by Trump this year.

Strait of Hormuz becomes flashpoint in US-Iran conflict
The Iranian Parliament on Sunday approved a measure to close the Strait of Hormuz after the United States bombed three nuclear sites in Iran. The strait, located between Iran and Oman, remains a critical oil choke point, and closing it could have serious implications for both the global and U.S. economy. Secretary of State Marco Rubio, in several Sunday interviews, warned against shutting down the strait, calling the move 'suicidal' for the regime. Rubio also called on China — Iran's most crucial oil customer — to encourage the country against shutting it down. 'I encourage the Chinese government in Beijing to call them about that, because they heavily depend on the Straits of Hormuz for their oil,' Rubio said on Fox News's 'Sunday Morning Futures with Maria Bartiromo.' Iran's Supreme National Security Council will ultimately decide on the move. The threat to block the narrow waterway comes in response to U.S. strikes on three nuclear sites in Natanz, Esfahan and Fordow, located inside a mountain. The Trump administration has argued the strikes, dubbed 'Operation Midnight Hammer, 'were a monumental success.' But it is unclear how much the sites were damaged or how it has set back Iran's nuclear program. The Strait of Hormuz's width and depth allow it to handle the world's largest crude oil tankers, and very few alternatives exist if it is closed, according to the U.S. Energy Information Administration (EIA). Approximately 20 million barrels, or 20 percent of global consumption, flowed through the strait in 2024. More than 80 percent of the crude oil and natural gas that passed through the Strait of Hormuz in 2024 was destined for Asian markets, with China, India, Japan and South Korea being the top recipients. These countries would likely be the most affected by any closure. But the U.S. market would also feel some impact if the strait were disrupted. The U.S. has been buying less oil from the Persian Gulf — importing about 0.5 million barrels per day in 2024, according to the EIA. Still, consumers are businesses are still likely to see increased prices, given that oil is traded globally. And it could take months for U.S. oil companies to drill more to compensate for those increased prices, the New York Times reports. Oil prices in the past month increased due to the escalating Israel-Iran conflict, and these are estimated to climb further if Iran were to block the strait. Experts have said they estimate oil prices could increase from $73 per barrel up to $120 per barrel if tankers are blocked. 'If we see any throttling back of the Strait of Hormuz, we'll see a massive increase in the price of oil, and that will impact everything in the U.S.,' Ramanan Krishnamoorti, a professor of petroleum engineering at the University of Houston, told ABC News this month. Iran has previously seized or interfered with tankers during heightened political tensions, according to the New York Times. While Iran's Supreme National Security Council has yet to make a decision, some experts are skeptical that the country will actually close down the Strait of Hormuz. Experts say the move would likely lead to a near-immediate response from the U.S., and it would be self-defeating to Iran's own market.
