The United States has conducted a simulated military operation using anti-ship weapons during a war game in the Philippines, as China expands its naval presence in nearby contested waters.
Newsweek has reached out to the Chinese Defense Ministry via email for comment.
Why It Matters
The Philippines—Washington's mutual defense treaty ally—is part of the First Island Chain, along with Japan and Taiwan, under the U.S. containment strategy, which seeks to restrict China's naval access to the wider Pacific Ocean by leveraging America-aligned territories.
According to a Pentagon assessment, the Chinese military has the largest navy in the world by hull count, with more than 370 ships and submarines in service. The Chinese navy has been operating around the Philippines, including deploying an aircraft carrier in late May.
During the ongoing Exercise KAMANDAG 9, the U.S. military deployed the Navy-Marine Expeditionary Ship Interdiction System (NMESIS) to the Philippines' Batanes Islands in the Luzon Strait—a key gateway for China to access the waters east of the First Island Chain.
What To Know
The U.S. Marine Corps said that it had strategically positioned the NMESIS—a ground-based launcher armed with two Naval Strike Missiles with a 115-mile range—on Sunday on one of the Batanes Islands for simulated maritime interdiction during KAMANDAG 9.
Maritime interdiction is defined by NATO as a naval operation intended to "delay, disrupt, or destroy" enemy forces or supplies en route to the battle area. The simulated operation was part of a rehearsal to secure and defend key maritime terrain, the U.S. Marine Corps stated.
Following insertion by a transport aircraft onto the island, the anti-ship weapon was remotely operated from the airfield into a concealed position to interdict maritime targets, the U.S. Marine Corps added, supporting the maintenance of open sea lines of communication.
Meanwhile, a "kill web" was formed to conduct maritime strikes, employing intelligence, surveillance, and reconnaissance assets to "find, fix, and track" targets. According to the U.S. Marine Corps, no live-fire was conducted during each fire support rehearsal.

This simulated Maritime Key Terrain Security Operation (MKTSO) was carried out by the Third Marine Littoral Regiment, a Hawaii-based U.S. Marine Corps unit that specializes in amphibious and littoral, or shoreline, warfare operations and deploys across the Indo-Pacific region.
In late April, the U.S. conducted another MKTSO using the NMESIS on Batan Island, simulating anti-ship strikes. The event coincided with the transit of a Chinese aircraft carrier through the Luzon Strait, moving between the Philippine Sea and the South China Sea.
What People Are Saying
The U.S. Third Marine Division said: "The synchronization of U.S.-Philippine forces during the KAMANDAG 9 MKTSO showcased the increased ability of the partnered militaries to coordinate complex, all-domain operations and further demonstrated the ironclad U.S.-Philippine alliance."
Lieutenant Colonel Patrick Schrafft, U.S. Third Marine Littoral Regiment's fire support coordinator, said: "The constructive kills executed during the KAMANDAG 9 MKTSO are yet another example of the [Third Marine Littoral Regiment]'s proven value proposition to the Combined and Joint Force."
What Happens Next
The U.S. is likely to continue its military exercises with the Philippines featuring anti-ship weapons to counter China's naval threat. It remains unclear whether the NMESIS will stay in the Southeast Asian nation after Exercise KAMANDAG 9 concludes on Friday.

Trump Trolls Iran With Post About 'Regime Change'
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. President Donald Trump asked on Sunday why there "wouldn't" be "regime change" in Iran if the country's government isn't able to "MAKE IRAN GREAT AGAIN." The U.S. president mused about the possibility on his social media website, Truth Social, writing: "It's not politically correct to use the term, 'Regime Change,' but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn't there be a Regime change??? MIGA!!!" Trump's comments came after multiple top Trump administration officials said that regime change was not the U.S.'s goal in launching a series of strikes against three Iranian nuclear facilities this weekend. "This mission was not and has not been about regime change," Secretary of Defense Pete Hegseth told reporters at the Pentagon on Sunday morning. Vice President JD Vance told NBC's Kristen Welker in a "Meet The Press" interview that the U.S. was not at war with Iran but rather with its nuclear program. This is a breaking news story. Updates to follow.

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.

Exclusive: Israel's Herzog Reacts to US Strikes—'Have to Defend Ourselves'
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The international community ignored Iran's major underground nuclear facility of Fordow for years, Israeli President Isaac Herzog told Newsweek in an exclusive interview following U.S. strikes against three nuclear sites in central Iran overnight. The Fordow nuclear facility, roughly 60 miles south of Tehran, was secret until 2009. Then-U.S. President Barack Obama said at the time it had jointly told the United Nations' (U.N.) nuclear watchdog that Iran had for years secretly built up a nuclear site near the city of Qom. Referencing the former president's words more than a decade-and-a-half ago, Herzog said Obama "exposed" the existence of Fordow, "but then the world let it happen." "It's ridiculous," Herzog said. "The IAEA [International Atomic Energy Agency] declared that they're non-compliant, and they're lying," the Israeli president added. "And the world says, 'Okay, what? What do we do about it?'" Referring to Israel, he continued: "Well, we have to defend ourselves, and we remove it." The U.S. launched strikes on Fordow, Isfahan and Natanz—three of Iran's most significant nuclear sites—early Sunday local time, dubbed "Operation Midnight Hammer." Major U.S. allies expressed support for the American strikes on Sunday while urging Iran not to respond. Tehran had promised retaliation and "irreparable damage" if the U.S. attacked its nuclear facilities prior to the strikes. Abbas Araghchi, Iran's foreign minister, on Sunday warned of "everlasting consequences" for what he termed "outrageous" U.S. attacks. The U.S. entry into the war came after Israel carried out what it called a "pre-emptive" campaign against Tehran's nuclear sites and personnel, as well as its ballistic missile and other military sites. Israel said Iran was getting close to having a nuclear weapon, which the U.S., and many of America's allies, have said is unacceptable. However, Iran maintains that its nuclear program is for civilian purposes—not for weapons. Israeli President Isaac Herzog visits a residential building struck by a missile launched from Iran, in Petah Tikva, Israel, on June 16. Israeli President Isaac Herzog visits a residential building struck by a missile launched from Iran, in Petah Tikva, Israel, on June 16. Associated Press Iran launched waves of drone and missiles at Israel shortly after. Both Israel and Iran continued their attacks following U.S. strikes. President Donald Trump hailed the strikes on Fordow, as well as the facilities at Natanz and Isfahan, as a "spectacular military success." "Iran's key nuclear enrichment facilities have been completely and totally obliterated," he added. Israel, while not pursuing Fordow, has for over a week carried out extensive airstrikes on Iran's nuclear sites, including Isfahan and Natanz, and killed a litany of senior nuclear scientists and generals. The U.S. military's B-2 Spirit bombers, equipped with "bunker busting" GBU-57/B bombs weighing in at 30,000 pounds, were widely considered the only pairing able to take Fordow, buried deep under a mountain, out of the equation. A U.S. submarine launched more than two dozen Tomahawk cruise missiles against the aboveground facilities at Isfahan around 5 p.m. ET on Saturday, just before U.S. aircraft entered Iranian airspace, General Dan Caine, the chairman of the U.S. joint chiefs of staff, said on Sunday. Washington used deception tactics and a host of fourth- and fifth-generation aircraft traveling ahead of B-2 heavy bombers to sweep for Iranian fighter jets and air defenses, Caine added. At 6:40 p.m. ET, the first B-2 dropped two GBU-57/B bombs at Fordow, followed by another site, the top general said. The rest of the munitions were dropped in the following 25 minutes, and Iran did not fire at U.S. aircraft traveling in or out of Iran, Caine added. Experts and officials said on Sunday it was too early to tell exactly how much damage has been done to Iran's network of nuclear sites. Preliminary assessments indicate all three facilities sustained "extremely severe damage," Caine said. In a Sunday afternoon Truth Social post, Trump pushed back against criticism from Republican lawmaker Thomas Massie of Kentucky, asserting that the U.S. had effectively "taken the 'bomb'" away from Iran by targeting the three nuclear sites. Massie has said that Trump needed congressional approval to launch the aerial attack. During an emergency U.N. Security Council meeting requested by Iran, Secretary-General António Guterres appealed for urgent action to halt the violence and revive negotiations over Iran's nuclear program. "We cannot—and must not—give up on peace," Guterres said, calling for a verifiable agreement with full access for U.N. nuclear inspectors to rebuild trust. Stressing the stakes, he warned that the world faces a clear choice between the path of escalation and that of diplomacy. "We know which path is right," he declared.
