Jiaolong Manned Submersible: A Decade’s Retrospect From 2002 to 2012

In July 2012, the People’s Republic of China successfully completed a 7,000-m dive in the Mariana Trench, deploying the Jiaolong manned submersible. It took only a decade for China to design, assemble, test, and launch its first national research submersible. The project was started in 2002, followed by 6 years of system design to integration, with dozens of domestic and foreign participants’ cooperation and contributions. Four sea trial cruises were carried out from 2009 to 2012 with the purpose of validating and upgrading system performance. During this time, the deepest dive was 7,062 m, which confirmed the system’s functionality and reliability. Although this research and development program has been very successful, it was a colossal project full of hardships and systematic challenges throughout the decade. This paper is a decade’s retrospect on Jiaolong’s research and development, including the project’s origin, organization and implementation, introduction to system performance, sea trial results, and future prospects.
