It is perhaps the most unlikely kind of military base. For more than two decades, a World War II-era ship, BRP Sierra Madre, has stood deliberately grounded in the remote, shallow waters of the fiercely contested South China Sea, carrying the Philippine flag and guarding against Chinese expansion.
But its future is increasingly precarious, and the ship has become a growing flashpoint in one of the world’s most disputed waters.
The Sierra Madre, marooned on Second Thomas Shoal, in the Spratly Islands, since 1999, is effectively a shipwreck. Rust has ravaged its sides and holes pierce its shell. Defense experts question how much longer it can last — and the Philippines faces a difficult decision about what to do next. So too might the US, which has a mutual defense treaty with Manila, and considers the South China Sea, one of the world’s busiest shipping routes, strategically important.

Attempts by the Philippines to deliver supplies to a handful of marines living on the ship have been repeatedly blocked by China, which has demanded the ship’s removal. Analysts say Beijing is effectively waiting for the ship to crumble, leaving the shoal unoccupied. On Sunday, Philippine and Chinese vessels collided twice as Manila attempted a resupply mission, the latest in a series of tense maritime confrontations.
Abandoning the ship would mark a difficult retreat for the Philippines. The Sierra Madre is “a symbol of how far and by how much our sovereignty and sovereign rights stretch,” says Jaime Naval, assistant professor at University of the Philippines.
Bringing construction materials, even to partially repair the Sierra Madre, is logistically complex — whether by air or water.

“Getting something through unmolested by sea is almost impossible unless you did something that was low-observable but there’s nothing in the Philippines inventory that has the speed or the stealth to get through all of that,” says Raymond Powell, a fellow at Stanford University’s Gordian Knot Center for National Security Innovation in the US.
Second Thomas Shoal has only one, very narrow entrance, which can easily be blocked, and Chinese ships can be quickly deployed from nearby Mischief Reef, which has been occupied by China since 1995, says Powell.
“Mischief reef is really in some ways the perfect weapon for a blockade,” he adds.

It was China’s seizure of Mischief Reef in 1995 that prompted Manila to run the Sierra Madre aground at Second Thomas Shoal. Both locations are less than 200 nautical miles from the coast of the Philippine island Palawan, and so are part of the country’s exclusive economic zone — meaning the Philippines has the right to exploit resources and construct in the area.
After the recent collisions, which the Philippines blamed on China’s “dangerous, irresponsible and illegal” behavior blocking its boats, China’s foreign ministry spokesperson Mao Ning (毛寧) said the Chinese coast guard had “lawfully” blocked Philippine attempts to send construction materials” to the ship, which it claimed had been illegally grounded.
Beijing claims almost all of the South China Sea — despite a UN tribunal finding this has no legal basis.
Collisions between Chinese and Philippine vessels last week are just the latest confrontation during a resupply mission. In August, Chinese coast guard vessels used water cannon against a similar Philippine resupply boat. In February Manila accused China of directing a military-grade laser at a Philippine vessel.
Analysts have warned that confrontations are becoming more intense, and frequent, and that there is an increasing risk of miscalculation in what is a long running and delicate dispute. The mutual defense treaty between Manila and Washington extends to armed attacks on Philippine armed forces, public vessels and aircraft — including those of its Coast Guard — anywhere in the South China Sea, the US state department has said. Were the situation to escalate, this could bring the US into confrontation with Beijing.
Tensions have risen to a level not been seen since 2014, when the Philippines airdropped food and water to Second Thomas Shoal to overcome a China-imposed blockade, said Harrison Pretat, associate director and associate fellow, of the Asia Maritime Transparency Initiative at The Center for Strategic and International Studies, a Washington-based thinktank.
Some have questioned if an airdrop could be used again to deliver supplies, but analysts say it is not a sustainable option. The Manila-based think tank Stratbase ADR Institute this week called for Manila to consider joint patrols with the US and other partners, with its president Dindo Manhit saying, “Only by working together can the Philippines successfully assert its right.”
Joint patrols, too, would raise difficult questions, said Pretat.
“If a US ship starts to accompany the resupply missions, are they going to continue to accompany them for every resupply mission in the future?” says Pretat, who added that such missions happen once or even twice a month.
It’s also unclear what a joint patrol would look like in practice, and these could risk further heightening tensions.
Patrols with partner countries other than the US could help tackle Beijing’s narrative that Washington is using the Philippines to stir trouble in the region, says Naval.
“The Chinese are trying to oversimplify the narrative [suggesting that] it’s just a battle between two big elephants. It’s not.”
Under president Ferdinand Marcos Jr, the Philippines has revived its alliance with the US, which had soured under his predecessor Rodrigo Duterte, but it has also strengthened ties with Japan and Australia.
Last week, General Romeo Brawner, chief of staff of the armed forces of the Philippines, said that it had begun superficial repairs on the ship.
It was sad to see the state of the living conditions where the small contingent of troops were staying, he said.
“We’re trying to improve that by making sure they have at least decent sleeping facilities, decent dining facilities, Internet,” Brawner said.
Naval has, in the past, interviewed soldiers who were deployed to the ship.
“Simply put, it makes you mad,” he says. Soldiers stay in small quarters, “eyeball to eyeball with everyone,” for months, he says.
Storms are severe and there is little comfort, other than a battery-powered TV playing the same movies on repeat.
Given the dilapidated state of the Sierra Madre, it’s unclear to what extent it can be salvaged, says Powell, who added that abandoning the ship, and surprising Beijing by running another vessel aground at a nearby shoal, could be an alternative option. Troops could be moved over to a new ship at an atoll nearer to the coast of Palawan, such as Sabina Shoal, he adds.
“It would be a defeat of sorts, but at the same time it would be a victory of sorts because they’d get to start afresh,” he says, adding that materials for long-term maintenance could be brought on board.
If the atoll were left unoccupied, it’s not clear whether China would seek to build on it, given that Mischief Reef is about 30km away, says Pretat.
Nobody knows how long the Sierra Madre has left before it succumbs to the elements, but Powell says there are concerns its collapse could come within months, not years.
“We have to be ready for the idea it could start tomorrow.”
Much attention is being paid to increasing security ties between Taiwan and the Philippines, and rightfully so. The stakes are potentially existential, as explored in “ Donovan’s Deep Dives: Taiwan, Japan and the Philippines need to face the common threat from Beijing” (Sept. 12, page 12). Getting less attention is that across the board the relationship is growing stronger, and both sides appear to be planning to put more of their eggs in each other’s baskets. Minister of Foreign Affairs Lin Chia-lung (林佳龍) in August last year confirmed plans to open a second Taipei Economic and Cultural Office (TECO) representative
On Oct. 2, after years of delays, Taiwan’s air force took delivery of the first two F-16V Block 70 fighter jets at Chihhang Air Base in Taitung County. In a sign of how eagerly anticipated this arrival was, speculation and rumors had been flying as to why they had been sitting for weeks in Hawaii en route to Taiwan. These are part of a total of 66 F-16V Block 70s on order. There are hopes the rest will arrive by the end of next year, but no one will be surprised if that extends into 2029 or even later. Worse,
Last week North Korea hit the headlines with a vow to fire up its loudspeaker systems to blare propaganda into the South, but the latest dispute comes against a backdrop of militarization of the border by Kim Jong-un that has been years in the making. Since April 2024, North Korea has been working on building a permanent fortified border through the demilitarized zone (DMZ) that divides the two sides, work that has led to a mine explosion that injured three South Korean soldiers and plunged ties to new lows. Here’s a brief guide to what is being built, what Pyongyang says it’s
Several years ago, the Ministry of Economic Affairs began encouraging legacy manufacturing enterprises to reposition themselves as tourist factories. In these places — which draw busloads of Taiwanese tourists but few international travelers — visitors can learn about the history of particular industries, observe production, join DIY workshops and gain an appreciation of the unglamorous but valuable skills that underpin Taiwan’s economy. Among the country’s most successful tourist factories are sites which make balloons, braised foods, cookies, fishing gear, ribbons and whisky. Few are so closely tied to local traditional culture, however, as Singang Incense Artistic Culture Garden (新港香藝文化園區) in
