This papercraft is designed by oniya. The Shinkai 6500 is a manned research submersible that can dive up to a depth of 6,500 m. It was completed in 1990 and has the greatest depth range of any manned research vehicle in the world. The only manned expeditions to have gone deeper were the dives of the Trieste bathyscaphe in 1960 and the dive of the Deepsea Challenger in 2012, both diving to Challenger Deep. However, the vessel could not navigate along the bottom of the sea bed. The Shinkai 6500 is owned and run by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and it is launched from the support vessel Yokosuka.
Two pilots and one researcher operate within a 73.5 mm thick titanium pressure hull with an internal diameter of 2.0 m. Buoyancy is provided by syntactic foam.
Three 14 cm methacrylate resin view ports are arranged at the front and on each side of the vehicle.
