The case of $$$ isn't that important if the concept would be approoved by the strategists and it would be profitable. Also, it always can be a Navy
black program.
The idea is actually very good, today there is a chance to build sub supercariers, but carrying small, fast and easy to manouver units.
Of course, this changes the entire concept of underwater war. Todays subs are too big to be carried by an even bigger submarine, but if submarine
units like jet fighters were introduced, war underwater would look just like air war.
This is a very interesting article, about the effect of supercavitation, which actually can revolutionise naval war.
