Fortified South China Sea artificial islands project Beijing’s military reach and power, say observers
- Filipino photographer brings fresh attention to island bases which analyst says act as ‘unsinkable aircraft carriers’ for PLA to hunt submarines
- But experts also see outposts as vulnerable to foreign forces during a conflict and challenges of isolation and distance from mainland China
Images taken by Philippines-based photographer Ezra Acayan revealed docks, radars, airports, military camps and large aircraft hangars on the seven Chinese artificial islands.
The photos, released by Acayan on social media last week, also showed multi-storey buildings, paved roads, sports fields, and basketball and tennis courts.
One photo on Mischief Reef showed two Type 22 catamaran missile boats, which incorporate stealth features and can carry up to eight YJ-83 subsonic anti-ship missiles.
These boats reportedly chased away Philippine news crews who tried to monitor Chinese movement in the region last year, according to Philippine media reports.

The photographer also captured an image of one medium-sized medium-range Y-8 transport aircraft in a hangar on Mischief Reef.
The Y-8, which has been continuously upgraded and produced, is a popular transport aircraft with many variants. The hangar where the Y-8 was stationed can shelter aircraft against hot, humid and high salinity environments but its construction does not appear strong enough to defend against enemy strikes.
On a corner of Cuarteron Reef, weapon systems similar to the Type H/PJ-26 76mm naval gun and H/PJ-13B defence gun – along with several soldiers - were seen on the top of two towers which provide basic anti-sea and anti-air firepower, and would serve as the last line of defence in a confrontation.
In the same image of Cuarteron Reef, a large radar similar to the SLC-7 three-dimensional early warning radar was seen on the ground. The anti-stealth radar could detect and track multiple targets and was capable of resisting saturation attacks, Chinese state media reported last year.

Two medical landing pads – with a red cross painted on a white square pad – could be seen on both Mischief Reef and Fiery Cross Reef. However, there was no visible human presence nearby.
“Looking at the images, the first thing that strikes me is that there’s not a lot of activity occurring in these bases. Clearly there are people there, but most of the images suggest a quiet rather than bustling or busy military base. Some of the structures also look in a state of disrepair,” said Malcolm Davis, a senior analyst from the Australian Strategic Policy Institute.
“Having said that – clearly the Chinese have made some progress in terms of making the bases a bit more hospitable,” Davis said, referring to the appearance of more trees on the islands.
“In terms of tactical use, these bases allow the PLA Air Force to forward deploy in a crisis to prepared bases, fully equipped with hardened aircraft shelters and other supporting infrastructure, for operations into the South China Sea.
“I think they also act as unsinkable aircraft carriers for the Chinese air force and navy’s anti-submarine warfare platforms to hunt submarines in the area.”
However, Davis said it was not known how well these bases would survive in a real war.
He said they could be used strategically to contest the transit of another state’s aircraft and vessels “potentially under declaration of an air defence identification zone, or more seriously, a blockade”.

Brad Martin, a retired US Navy officer and a senior policy researcher at the US think tank Rand Corporation, echoed Davis’ views.
“The PLA having a presence on these islands expands its ability to conduct surveillance, potentially threaten shipping, and even reduce warning time should it decide to take military action against the Philippines or [another] littoral state.”
Martin, too, believed the strategic advantage offered by the island bases might be offset by their vulnerability during a conflict.
“The islands must be resupplied and reinforced, and the PLA might find that a challenge,” he said.
What are rival claimants building on South China Sea islands and reefs?
China has built seven artificial islands in the South China Sea, creating more than 1,000 hectares (2,470 acres) of new land since 2013, according to the CSIS Asia Maritime Transparency Initiative. And such moves have heightened fears among rival South China Sea claimants, such as Vietnam and the Philippines.
However, despite the islands being militarised, a Chinese military magazine has openly highlighted their weaknesses because of their considerable distance from the Chinese mainland, their small size and the multiple routes from which they could be attacked.
