The Harbin SH-5 is a Chinese flying boat used for anti-submarine warfare and search and rescue, with service dated from 1986 through the video's recording in 2020. Its published specifications need caution because some figures appear dramatically inflated while others seem more plausible. The figures provisionally accepted here give an endurance of about fifteen hours on two engines and a maximum-fuel range of roughly 2,568 nautical miles. Those numbers place it in the same broad long-range category as Japan's ShinMaywa US-1A and US-2.
