While it may not be able to adeptness the aforementioned seven-mile mark as James Cameron's abyssal vessel, the Jiaolong manned submersible could accommodate so abundant more.

The Jiaolong is an 8.2-meter long, 22-ton accurate analysis barge and the aftereffect of years of stealth development by the Chinese government. It was initially devised as allotment of the 863 Plan, a high-tech R&D action allowable in 2002.
The Jiaolong fabricated its aboriginal test-run in 2010, diving to 3000 meters. A consecutive analysis in 2011 saw the sub dive accomplished 5000 meters, authoritative it one of alone 5 submersibles in the apple able of above 3500 meters—the others acceptance to the US, France, Russia and Japan. Tang Jialing, Fu Wentao and Ye Cong comprise the submersible's three-man crew. Ye both helped architecture the barge and has been its pilot on 28 of the antecedent 37 dives.
If the sub does adeptness its operational absolute of 7000 meters during an accessible test-dive in June, the Jialong will become the alone sub of the 5 able of diving above 6500 meters. At 7km beneath the surface, the Jiaolong will accept admission to 99.8 percent of the seafloor—assuming it can bear the crushing pressure.
With that array of range, the Jiaolong will play an capital role in abyssal exploration, both accurate and commercial. The aggregation that helped architecture and body the submersible, the China Ocean Mineral Assets R&D Association (COMRA) has affairs with the International Seabed Authority to photgraph and analysis 75,000km swaths of the seabed in acknowledgment for rights to "explore minerals and added assets for bartering purposes in this breadth already the technology matures," said Jin Jiancai, COMRA's secretary-general.
And as the amount of adored metals and attenuate apple aspect bolt steadily rise, the adeptness to analyze around the absolute undersea landscape, which covers 70 percent of the Earth, and abundance consecutive discoveries are abiding to accommodate a ample compensation for any country able to adeptness them. "The ambit amid 6,000 and 7,000 meters beneath sea akin is affluent in resources," Yan Kai, the team's arch architect said. "Therefore, we charge to accept our submersibles analyze and conduct analysis in this range." [Jiaolong Wiki, BBC News, WSJ, Old Salt Blog, Asian Scientist, Subsea Apple News]
