China has completed production of the world's largest amphibious aircraft, state media has said, the latest effort in the country's program to wean itself off dependence on foreign aviation firms.

The state-owned Aviation Industry Corporation of China (AVIC) unveiled the first of the new planes, dubbed the AG600, Saturday in the southern port city of Zhuhai, the official Xinhua news agency reported.

The aircraft, which has a maximum range of 4,500 km (2,800 miles), is intended for fighting forest fires and performing marine rescues, it said.

At around the size of a Boeing 737, it is far larger than any other plane built for marine take off and landing, Xinhua quoted AVIC's deputy general manager Geng Ruguang as saying.

However, its wingspan is considerably smaller than that of the H-4 Hercules, known as the Spruce Goose, which was designed in the 1940s to carry Allied troops into battle. It is regarded as by far the largest seaplane ever built although it only ever made one flight, in 1947.
