Traits of strugglers

Endeavor is a 10,000-meter manned submersible independently designed and integrated by China. Its successful development has significantly improved the capability of manned deep diving technology and equipment and the level of independent innovation in China, promoted the development of submersible to the whole deep sea pedigree and function, and provided another weapon for China to explore the mysteries of deep sea science and protect and rationally utilize marine resources.

In the second phase of the 10,000-meter sea trial mission, the sea trial team overcame difficulties such as typhoon, rainy weather, high temperature and high sea conditions, carried out a number of acceptance tests, and also carried out the joint operation of the deep-sea video lander "Canghai" and "Struggler".
