The Harbin SH-5 (Chinese: 水轰五型, where "水轰" is short for "水上轰炸机"(Shuishang Hongzhaji), literally "seaborne bomber") is a Chinese maritime patrol amphibious aircraft intended for a wide range of duties, including aerial firefighting, anti-submarine warfare (ASW) and air-sea rescue (SAR). They are used for maritime and search and rescue operations. Only 6 units have been built not counting the prototype; all are in active service except one crashed on May 30, 2013. One is outfitted as a firefighting plane.

Design and development[edit]

Research to build a seaplane capable of replacing Beriev Be-6s in service was initiated by the PLANAF in 1968, with designers overhauled from "Objective 3/17", a supersonic canard-wing fighter project. The first prototype flew in 1976; further units were delivered between 1986 and 1990.

Variants[edit]

SH-5
The only production series, 1 prototype and 4 production aircraft built.
SH-5A Maritime patrol aircraft
Some SH-5's converted for ELINT duties.
SH-5B Firefighter
One SH-5 was rebuilt for firefighting duties.[3] It is designated as PS-5.
However, by Chinese source,[4] there were total of 7 SH-5 were produced: 3 SH-5X Prototype, 3 Maritime patrol aircraft, and 1 SH-B Firefighter.
