Yes, and it’s not 1957 any more.... :P
Say hello to the 200-knot-plus VA-111 Shkval torpedo. Currently on the world arms market for anyone with the bucks. https://en.wikipedia.org/wiki/VA-111_Shkval
We don’t have a supercavitating torpedo - our guided torpedoes go about 55kts and have about an 8km range. But we’re promised one Real Soon Now®.
Did I mention the Shkval is in its second iteration and has twice the range of our torpedoes?
