The „Shenhai Yongshi“ (Deep-Sea Warrior) can dive to 4,500 m and is considered an important stepping stone to China’s 10,000 m manned submersible which is presently under construction and set for explorations in the Mariana Trench in 2020. 95 % of the Shenhai Yongshi is claimed to be „made-in-China“, with a focus on underwater acoustic doppler velocity log and communication systems.
