Here are some images of Bandai's 1/48 scale Jamstec Shinkai 6500 Manned Research Submersible.
This is one of the best kits I have seen in a long time. The detail is amazing plus there are lots of moving parts and removable panels. It even comes with a lighting pack.
What I found interesting is the lack of glue that was required in assembling such a complex kit.
It also comes with one of the most complex display stands I've seen.
However this kit isn't cheap. It retails at around $100 CDN.
The Shinkai 6500 (しんかい) 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 expedition to have gone deeper was the dive of the Trieste bathyscaphe in 1960. 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.
