Description
The Harbin SH-5 is a Chinese four-engine amphibious maritime patrol aircraft designed for anti-submarine warfare, air-sea rescue, and aerial firefighting. Manufactured by Harbin, the aircraft entered service with the People's Liberation Army Naval Air Force in 1986. It is known as China's first indigenously developed large amphibious military aircraft.
Development
The PLANAF initiated research for a new amphibious aircraft in 1968 to replace its fleet of Beriev Be-6 seaplanes. Design personnel were reassigned to the project from the "Objective 3/17" supersonic fighter program. The first prototype completed its maiden flight in 1976. Production aircraft were delivered between 1986 and 1990, with total production reaching seven units across all variants and prototypes.
Design
The SH-5 is powered by four Dongan WJ5A turboprop engines rated at 2,350 kW (3,150 hp) each, driving four-bladed constant-speed reversible propellers measuring 3.8 meters in diameter. The aircraft carries an eight-person crew and incorporates a nose radome housing a Doppler search radar, along with a Magnetic Anomaly Detector boom extending from the tail. It has a wingspan of 36 meters, a length of 38.9 meters, and a maximum takeoff weight of 45,000 kg.
Armament
The aircraft is equipped with four underwing hardpoints capable of carrying up to 6,000 kg of stores. External payload options include C-101 anti-ship missiles, anti-submarine torpedoes, depth charges, mines, and conventional bombs.
Operational History
The PLANAF took delivery of four operational SH-5 aircraft in 1986. All active units were assigned to the North Sea Fleet, operating from a base near Qingdao in Shandong province.
