BEIJING • China's domestically developed AG600, the world's largest amphibious aircraft, performed its maiden flight yesterday, from an airport on the shores of the South China Sea, the latest step in a military modernisation programme.
Beijing has stepped up research on advanced military equipment as it adopts a more muscular approach to territorial disputes in places such as the disputed South China Sea, rattling nerves in the Asia-Pacific region and the United States.
State television showed live images of the AG600 lifting off from Zhuhai airport in the southern province of Guangdong.
Xinhua news agency said the aircraft, code named "Kunlong", was the "protector spirit of the sea, islands and reefs".
It had previously been scheduled to make its first flight earlier this year, but it is unclear why it was delayed after ground tests took place in April.
State-owned Aviation Industry Corp of China spent almost eight years developing the aircraft, which is roughly the size of a Boeing 737 and is designed to carry out rescues at sea as well as battle forest fires.
However, state media has also noted the plane's potential use in the South China Sea, where China, Vietnam, Malaysia, the Philippines, Taiwan and Brunei all have overlapping claims.
The AG600's chief designer, Mr Huang Lingcai, was quoted in the official China Daily earlier this month as saying the plane can make round trips without refuelling from the southern island province of Hainan to James Shoal, claimed by China, but which is located close to Sarawak in Malaysian Borneo.
Powered by four turboprop engines, the AG600 can carry 50 people during maritime search-and-rescue missions, and can scoop up 12 tonnes of water within 20 seconds for fire-fighting trips, according to state media.
The aircraft has received 17 orders from China's government departments and Chinese companies. It has a maximum flight range of 4,500km and a maximum take-off weight of 53.5 tonnes. It can use conventional airports and also land and take-off from the sea.
China is in the midst of a massive military modernisation programme, ranging from testing anti-satellite missiles to building stealth fighters and the country's first indigenous aircraft carrier, to add to an existing one bought from Ukraine.
