Subi Reef, China, Spratly Islands
Updated August 29 2024
Subi Reef, China
Subi Reef is an advanced military island developed, maintained and operated by the People's Republic of China (PRC). This island should be considered in context of being one of three Chinese military islands in the Spratlys in an equilateral triangle, along with Fiery Cross Reef and Mischief Reef.
This island is shaped as a "C" around a 3.82 mile diameter coral atoll. The island is 3.45 miles in diameter, with an extensive lagoon. It extends approximately 60% around the outside. It has a significant airport and aircraft facilities. When we see current photographs in the news (not reproduced here), it reminds me of Atlantic City, Macao, or even O'Hare Airport. Dense, modern buildings, lots of construction activity, and airport technologies are visible. There are four navigation lights demarking the channel into the reef.
The single island is in the shape of a C or an open mouth, with an overbite. This is different than the development of other atolls, where they fill in the center.
There is a well defined channel carved into the Reef to the south allowing fishing and naval access to the lagoon. We see four boats in the lagoon and one boat along the port dock. Location: 0°54'23"N 114°07’51”E. Satellite Imagery for the center of the island, ending at the tip of the bottom of the "C", is 5/10/2022. The Western portion of the island is 5/16/2022.
At the tip of the bottom of the "C", we see a significant AA Cannon emplacement with at least two cannons, and possibly more. We also a different structure. Missile launchers with retractable covers. These are elevated, and look to be the height of a one to two story building. They have the 'tell-tale' sliding roof that takes up half the space, this time in a uniform standard white, and they are located at the very tip of the bottom "C" at the furthest point on the island. Eight missile launch pods on the bottom of Subi Reef Island.
I am also amazed with the number of hangars connected to the runway that seem to be made of concrete, and could store aircraft. There are at least 24 at the southern end of the runway. From a distance, this is a well laid out island fortress, with living quarters to the North, and aircraft hangers and other military equipment to the south.
Subi Reef is located 14 miles west of Thitu, which is the one Philippine strategic island in the Spratlys.

Subi Reef is located 14 miles west of Thitu, which is the one Philippine strategic island in the Spratlys.
This is a fully militarized island, according to U.S. Admiral John C. Aquilino, in a Reuters news interview given during a tour of the Spratly Islands in a U.S. Navy reconnaissance aircraft that flew near these features, and was published March 21, 2022. According to U.S. Admiral Aquilino, Subi Reef, Mischief Reef and Fiery Cross are fully militarized islands occupied by PRC China.

Subi Reef runway is 1.95 miles long with aircraft parking at either end. We will rotate the image for the next few discussion points. We see 28 aircraft hangars, with 20 of them being smaller than the 8 that appear much larger. We also see many of the white radomes on towers, and we see another cannon building on the Southern end of the airfield, as seen here, and another at the other end by base housing. We also see a helicopter.
At the bottom of the C, at the entrance to the bay, we see a pair of white radomes on towers, a common white / gray building structure we have seen before on many islands with at least one cannon on the roof (the cannon building - image on left). The structure of the building below, what we call the cannon building, is similar and we have seen it on other islands in the South China Sea.
We see a strange formation set into the ground, with a rectangle etched with concentric circles, a small rectangular box in the center, and one to the left. This is the first time I have seen this and it looks important. Image on right.

At the Northern end of Subi Reef we see base housing, two hospital facilities, and some communication towers. We see a mandarin character in the grass just East of the running track and ten basketball / soccer courts.
We have seen something like this blue rectangle, which appears to be almost at ground level, and close to the water. Not sure what it is...but it is on one of the other fortified PRC islands near a pier.
