Chinese researcher attributed Hainan’s strategic location, its complete defense facilities and the effectiveness of deploying guided missile nuclear submarines as the major three reasons behind China’s decision to build its second aircraft carrier base in Hainan Island.

Canada-based Kanwan Defense Review reported recently that the basic construction of China's second People's Liberation Army Navy aircraft carrier base on Hainan was completed in November 2014. The base incorporates a pier which can dock large ships on both sides, suggesting that both carriers can dock at the PLA Navy's carrier bases at the same time. The new base is 700 meters long, making it the longest carrier berths in the world.

Ma Yao, a researcher with Shanghai International Studies University, made the analysis published by thePaper.cn. First reason Ma said was that Hainan navy base is comparatively close to the three strategically important straits -- Malacca Strait, Lombok Strait and Sunda Strait, making it easier for its naval fleet’s composition. Ma also said the base can protect its comparatively weak oil passage to ensure its economic development.

Second reason was that Hainan Island has equipped with quite advanced defense facilities after years of development, providing enough support to the naval base.Submarines are an inseparable underwater forces for naval fleet’s composition, Ma said, adding that the South China Sea is the best place for submarines among all four seas surrounding China.

Thirdly, the Hainan base is good for the effectiveness of navy’s nuclear force with its deeper waters and wider rims. That was why China has in recent years deployed guided missle nuclear submarines in the South China Sea, Ma pointed out.
