LemonHead asked:
......is X20. Is that evaporated water?
No, it is a secret experimental Mini Sub desiged to break the H2O Barrier. It is launched from the torpedo tube in a regular sub. The initial drive is an H2O2 turbine driven propellor. This drive is dropped after cavitation on the propellor starts. The final drive is a type of Aquatic Ramjet, using pure HTP with a secret catalist, transforming compressed seawater into superheated steam.
The researchers AIM for 1 M2O(1 Mach in H2O)
