China’s indigenously-developed AG600 large amphibious seaplane conducted its first sea-based test flight on Sunday morning in Qingdao, east China’s Shandong Province, marking a new milestone in the program. The seaplane sailed on the waters and then took off at 10:18 am to fly back to Shanzihe Airport. The AG600 prototype used for the test flight, operated by four crew members, took off at 9:28 am from Shanzihe Airport in Rizhao, Shandong province, and landed at 10:14 am on a designated area of the Yellow Sea off the neighboring city of Qingdao after a 46-minute flight. It completed a number of test assignments during the operation.
The AVIC AG600 Kunlong (Kun Dragon) is a large amphibious aircraft designed by AVIC and assembled by CAIGA. The AG600 is China’s second amphibious aircraft, after the SH-5, which was developed in the 1970s for military purposes and has been retired for a long time. With a length of 37 meters and a wingspan of 38.8 meters, the AG600 is roughly the size of a Boeing 737. Powered by four domestically designed WJ-6 turboprop engines, it has a maximum takeoff weight of 53.5 metric tons. These specifications make it the world’s biggest amphibious aircraft, surpassing Japan’s ShinMaywa US-2 and Russia’s Beriev Be-200. Currently, there are two AG600 prototypes under testingï¼one in flight tests and the other in ground-based static tests.

Once in service, it will put an end to the absence of a large rescue aircraft in China and will be very useful in the national emergency rescue and disaster relief systems. It also can be refitted to conduct marine environmental inspections and marine resource surveys, as well as personnel and supply transportation. The aircraft is designed for land and water takeoffs and landings and has an operational range of more than 4,000 kilometers. It can rescue up to 50 people during a maritime search and rescue mission. For forest fire-fighting, it can collect 12 tons of water from a lake or sea in 20 seconds and use it to douse blazes over an area of about 4,000 square meters
The amphibious plane is one of three large-size aircraft to emerge from the nation’s efforts to become a top-tier player in the global aviation sector, joining the Y-20 strategic transport planeï¼delivery of which began in July 2016 to the Chinese Air Forceï¼and the C919 narrow-body jetliner, which is being flight-tested. Development of the AG600 was approved by the central government in June 2009 and began in September that year. Tens of thousands of researchers and engineers from more than 160 domestic institutes, enterprises and universities took part in the program.
Compared with other rescue platforms such as helicopters and ships, the AG600 is faster and has a longer range and greater flexibility.
