The AVIC AG600 (Kunlong, 鲲龙) is a large amphibious aircraft designed by AVIC and assembled by CAIGA. Powered by four WJ-6 turboprops, it is one of the largest flying boats with a 53.5 t (118,000 lb) MTOW. After five years of development, assembly started in August 2014, it was rolled out on 23 July 2016 and it made its first flight from Zhuhai Airport on 24 December 2017; it should be certificated in 2021, with deliveries starting in 2022.

Development

The AG600 was previously known as the TA-600;[2] it was designated the Dragon 600 before TA-600.[3] After five years of development, CAIGA started to build the aircraft in August 2014, for a first flight targeted at the time for 2015.[4] Assembly was still on its way in October 2015.[5] The prototype was rolled out on 23 July 2016 at the Zhuhai AVIC factory.[6] At the roll-out, AVIC targeted a maiden flight by the end of 2016 and it has then gathered 17 orders, all from the Chinese government including the China Coast Guard, AVIC does not expect to produce it in large numbers.[2] Target markets also include export sales, with island countries such as New Zealand and Malaysia having expressed an interest.[7]

On 24 December 2017, it made its maiden flight from Zhuhai Jinwan Airport.[1] In May 2018, AVIC planned to have Civil Aviation Administration of China type certification completed by 2021 and deliveries starting in 2022.[8] After transfer from Zhuhai to Jingmen, the prototype started low-speed taxiing on the Zhanghe reservoir on 30 August 2018, it should takeoff from water before the end of 2018.[9] It completed high speed water taxi tests in October 2018.[10]

Further variants may be developed for maritime surveillance, resource detection, passenger and cargo transport.[11] It is one of the three big plane projects approved by the State Council of China, with the Xi'an Y-20 military transport and the Comac C919 airliner.[12]

Design

The AG600 amphibious aircraft has a single body flying boat fuselage, cantilevered high wings, four WJ-6 turboprops and tricycle retractable landing gear.[11] It can operate from 1,500 by 200 m (4,920 by 660 ft) stretches of water 2.5 m (8.2 ft) deep,[6] and should be able to conduct Sea State 3 operations with 2 m (6.6 ft) waves.[12] It was developed for aerial firefighting, collecting 12 t (26,000 lb) of water in 20 seconds and transporting up to 370 t (820,000 lb) of water on a single tank of fuel (31 rotations), and search and rescue, retrieving up to 50 people at sea.[6]

Assembled by CAIGA, it is 36.9m long and has a 38.8m wingspan, its MTOW is 53.5 t (118,000 lb) from paved runways or 48.8 t (108,000 lb) from choppy sea.[2] AVIC claims it is the largest amphibious aircraft.[6] It is heavier than the 41 t (90,000 lb) MTOW Beriev Be-200 or the 47.7 t (105,000 lb) ShinMaywa US-2, but lighter than the prototype-only 86 t (190,000 lb) Beriev A-40. Previous seaplanes were heavier, as the 75 t (165,000 lb) Martin JRM Mars or the prototypes 100 t (220,000 lb) Blohm & Voss BV 238, 156 t (345,000 lb) Saunders-Roe Princess or 180 t (400,000 lb) Hughes H-4 Hercules.

It could access remote atolls in the South China Sea’s Spratly Islands, claimed by several bordering nations,[3] as the South China Sea is subjected to territorial disputes.[13] It can fly in four hours from the southern city of Sanya to James Shoal, the southernmost edge of China’s territorial claims.[14]
