Airbus Defence and Space imagery shows changes to Fiery Cross Reef observed between February and March 2015. Noteworthy is the beginning of airfield installation in March, and the relocation of some dredging activity out of the harbour. ( CNES 2015, Distribution Airbus DS / Spot Image / IHS) 1569026

Satellite imagery shows that China has begun building a runway on reclaimed parts of Fiery Cross Reef in the Spratly Islands
The imagery, provided by Airbus Defence and Space, also shows China building islands on Subi Reef that if linked up would provide enough land for another airstrip
China has begun to build its first airstrip in the Spratly Islands, according to IHS Jane’s analysis of Airbus Defence and Space satellite imagery taken in March.

The 23 March images show a paved section of runway 503 m by 53 m on the northeastern side of Fiery Cross Reef, which China began to turn into an island in late 2014. Paving and ground preparation of other sections of the runway has also begun further along the island. In addition, workers have paved about 400 m by 20 m of apron.

Other imagery taken in March also shows China could be building a second airstrip-capable island on Subi Reef.

China’s island building at Fiery Cross Reef has created a landmass that is capable of housing a runway about 3,000 m long. This would be well within the parameters of existing People’s Liberation Army Air Force runways on mainland China, which vary in length from about 2,700 m to 4,000 m at most.

The runway at Woody Island in the Paracel Islands was about 2,300 m before upgrade work started there in 2014; satellite imagery suggests China is also expanding that to be about 3,000 m long.

The 23 March imagery of Fiery Cross Reef also shows further dredging on the new island’s southwestern side, close to the extant platform that China originally built on the reef. The imagery also shows floating cranes consolidating the integrity of new island’s harbour by placing concrete blocks on the interior walls; an exterior sea wall has also been extended, presumably to provide better protection for ships in port.

Airbus imagery taken of Subi Reef – also in the Spratlys – on 6 February and 5 March shows land reclamation on this site too. The 6 February image shows three islands being created. By 5 March, at least nine dredgers are creating larger landmasses on the reef that if joined together could create enough land for another 3,000 m-long airstrip.

While Fiery Cross Reef is to the west of the Spratly Islands archipelago, Subi Reef is on the north side of the island group and is only 25 km from Thitu/Pagasa island, which is occupied by the Philippines and has a civilian population.

中国在南沙群岛的第一条机场跑道，正在建设中。2015年2月和3月拍摄的永暑礁卫星图片对比显示，机场安装已于3月开始 

卫星图片还显示渚碧礁上的建设如果连接起来，能提供足够的土地给另一个简易机场。

3月23日的卫星图片显示，铺设在永暑礁东北侧的503米*53米的跑道的一段，跑道其他部分的铺设和地面准备正在沿岛进一步展开。此外，工人已经铺设400米*20米的停机坪 

永暑礁吹砂造陆之后，足够容纳一条3000米长的跑道。这和中国大陆上的军用跑道长度很吻合，那些军用跑道大约在2700米到4000米之间。西沙永兴岛的机场跑道在14年升级之前，约2300米，卫星图片显示现在已经升级到3000米长 

卫星图片显示永暑礁新岛的西南部正在进一步的疏浚，靠近永暑礁之前的堡垒建筑。浮吊正在内墙码放水泥块以巩固新岛港的完整性，外堤也已延伸，为在港船舶提供更好的保护。 

2月6日拍摄的渚碧礁上卫星图片显示，3个小岛正被创造出来。到了3月5日，至少9艘挖泥船正在创造一个更大的陆地，如果连接起来，有足够的陆地容纳一个3000米长简易跑道。 

永暑礁位于南沙群岛的西部，渚碧礁位于北部，距离菲律宾非法侵占的中国中业岛只有25公里。
