Shinkai 6500
Sunlight penetrates only 200 meters below the surface of the sea. But around 95% of the water in the oceans is deeper than 200 meters. This display features an actual-size model of the Shinkai 6500, the world's deepest manned research submersible, ready for you to climb into the cockpit and take a dive.

The LE-7A is a high performance engine that obtains thrust by burning mixed gases of liquid hydrogen and liquid oxygen, and is used for the first stage of Japan's main rocket, the H-IIA.
