Looking like an airplane, the “slim girl” with lemon color is actually a underwater glider named “Haiyan”. It is an unmanned underwater vehicle developed independently by Tianjin University with complete intellectual property rights. It can measure sea water temperature, salinity, noise and so on for a long time in a large area.

This “deep sea warrior” can reach a depth of 4500 meters. The manned submersible is the second deep-sea submarine after the “Jiaolong” in China. This scale model is about 1.7 meters long shrunk at 1:40 in comparison with the real submersible. (Translated by Xu Pengfei, Fathom Language Limited)
