Is this an attempt to silence the perception and to rid any worries about how US wouldn't allow the BYG to be integrated into the Shortfin Barracuda?
Another interesting sales pitch here:
Arguably the best platform? Don't know 'bout the hydrodynamic noise and can't comment how how good it will be compared to the Soryu's, but I like their pumpjet
Finally with to end with a bit of French flair, DCNS made this interesting comment:
"Germany and Japan hope the Barracuda Shortfin is indeed the most advanced submarine you’ll never see."
I say, Let the race begin!
