...... ..The SH-5 (Shuishang Hongzha-5, or ShuiHong-5) is the amphibious aircraft developed by Harbin Aircraft Manufacturing Corporation (HAMC) in the 1980s. As its designation implies, the aircraft was originally intended for anti-surface and anti-submarine warfare, but lack of suitable weapons resulted in only four examples being built for maritime patrol and surveillance role.
