China's new manned submersible has finished its first ocean expedition, according to Science and Technology Daily.

The manned submersible, Shenhai Yongshi (Deep Sea Warrior), can reach a depth of 4,500 meters.

It conducted 17 dives in 17 days during the recent expedition, with an average of more than eight hours in the water per dive, the newspaper said. Four dives were conducted within a 52 hour period.

In October 2017, the submersible was loaded aboard the ship Tansuo-1 to carry out its first deep sea tests off the shore of Sanya in southern China's Hainan Province.

The development of the submersible took eight years and involved over 90 Chinese organizations and companies. The submersible will make more than 30 dives in the South China Sea and southwest Indian Ocean.
