The Fujian is equipped with an electromagnetic aircraft launch system (EMALS), making it the world's second aircraft carrier to use electromagnetic catapults, after the US Navy's USS Gerald R Ford.China's first carrier, the Liaoning, a refit of a Soviet-era ship, was commissioned in 2012, followed by the indigenously built Shandong in 2019.The Fujian is the largest of China's three carriers, with a full-load displacement of more than 80,000 tonnes. Fujian-based aircraft including the J-15T, J-35 and KJ-600 have successfully completed catapult-assisted take-off and arrested landing training on the carrier, according to China's Defence Ministry.All three Chinese carriers - Liaoning, Shandong and Fujian - are conventionally powered.Analysts say that with tensions on the rise with the US, China may build more aircraft carriers to operate on various global maritime routes, including the Indian Ocean.The CSIS report says submarines and other forces could be used to threaten Chinese navy carrier groups as they pass through strategic waterways.Further out to sea, carrier-based aircraft could also be used to strike Chinese carriers, with satellites supporting surveillance and targeting, while attacks on sensors
and communications could disrupt PLA operations.Christopher Sharman, director of the China Maritime Studies Institute at the US Naval War College, told the Post that the undersea vulnerability identified in the report "remains significant today", although it was "not a static weakness".In recent years, the PLAN (People's Liberation Army Navy) has invested heavily in capabilities intended to improve its awareness of and ability to predict the undersea operating environment, Sharman said.However, he added that important gaps remained, saying PLAN-affiliated authors acknowledge that China's meteorological and oceanographic capabilities still lag those of the US Navy."This comparative lack of knowledge about the undersea ocean battlespace remains an impediment to PLAN submarine and anti-submarine warfare operations, particularly beyond the first island chain," Sharman was quoted as saying by the Post.Timothy Heath, head of defence research firm Perceptum, said anti-submarine warfare remained a challenge for China, particularly because US submarines are among the quietest in the world.He also said Japanese intervention in any conflict over Taiwan would raise the stakes, because Japan could seek to target Chinese warships operating near its coast, according
