The Harbin SH-5 is a four-engine, long-range amphibious sea patrol flying boat used by the Chinese naval aviators . The type is used to locate and combat over and underwater targets, the laying of mines , the search and rescue service as well as freight transport. Since the performance of the design was unsatisfactory, production ended after just four series machines. A version as a fire fighting aircraft was tested.
history
Already at the beginning of 1968 a successor to the Beriev Be-6 used in naval aviation - a design from the 1940s - was requested. The tender went to the Harbin aircraft factory, whose design Schuischang Hongzhaji 5 or SH-5 had already been approved by the authorities in December 1968. The detailed draft was completed by February 1970 (according to other sources by June 1969). In October 1970, the production of the first static prototype 01 began, which was completed in October 1971. New manufacturing techniques such as chemical milling of integral carriers, countersunk and sealed rivets and spot welding were used in the construction for Chinese aircraft construction. For unknown reasons, the structural load tests did not begin until August 1974. At the same time, the first flying prototype 02, which was completed in December 1973, was already in production.
The relocation to the flight test site did not take place until October 1974, when tests on water took place there. The first 23-minute flight did not take place until April 3, 1976. After a further development and testing period, which was typically protracted for this period in Chinese aviation, the construction of four series machines began, and a further prototype was not planned. The series machines with the numbers 9113, 9123, 9133 and 9143 were completed by November 1984; the trials continued until 1985. The performance of the type was insufficient, so no further aircraft were built. The series machines went into service in September 1986 with the 3rd Independent Regiment at the Qingdao naval base . In addition to the poor performance, there was no originally planned armament with anti-ship missiles . This and the inadequate propulsion power only made missions possible in the form of surveillance flights at low and medium altitude; the type remained unsuitable for the originally intended long-range anti-ship missions or fast transfers.
At least one machine was converted into a fire-fighting aircraft with a capacity of six tons of extinguishing water.

The fuselage is not designed as a pressurized cabin . The wings of the shoulder wing have an area of 144 m². The maximum speed is 555 km / h and the patrol speed is 230 km / h at a service ceiling of 7000 m. With a maximum fuel load, the range is 4570 km, the empty weight is 26,500 kg and the maximum take-off weight is 45,000 kg.
They are equipped with a type DPL-1 (Type-773) Doppler navigation radar in a small radar nose and an INS navigation system. The distinctive tailspur contains a MAD detector for magnetic anomalies. The armament consists of a twin weapon tower on the back of the hull and four external load carriers under the surfaces for anti-ship missiles or torpedoes (three per pylon). In addition, the internal weapons bays in the rear fuselage to depth charges , mines, bombs, sonar bombs and rescue equipment to record. The possible total weapon load is 6000 kg.
