The Washington Post reports China has finished its first airstrip in the hotly-contested Spratly Island chain in the South China Sea, according to new satellite photos released by IHS Janes. The airstrip, located on Fiery Cross Reef, is more than 3,000 meters long and appears to be complete due to the new presence of runway heading markings and helipad designators. Fiery Cross is just one of three reefs in the Spratly group of islands that China has built airstrips on. Currently, airstrips of the same length are under construction on Mischief Reef and Subi Reef. According to IHS Janes, a defense analysis company, the completion of the runway indicates that China will soon be able to ferry in more supplies and start air patrols over the disputed island chain.
