You can get whole PDF paper but it's mostly in japanese. Still the abstract says it all.

But it took me an hour.

Interesting abstract.....

I can not confirm nor deny....

Non sence... The little prop powers the turbo drive that lets it travel at the speed of sound underwater...:rotfl:

of course... The article could be right... I guess the large prop helps it stay quiet, and produce speed effectivly because of its shape... and maby the smaller prop does like the artical says... or is some kind of thing to fool a distroyers listening equipments... to make it sound faster than it is... could also be there to fool homeing torpedos... (noise fools them...) may add to its speed when staying quiet... but im just guessing... I could keep speculating...
