Even if it failed he called it the greatest succes in history
For all we know, the drone originally was meant to be used above water
The terrorist state does it again.
I don’t think that it has a lot of direct relevance for Ukraine. The two projects in question (tsunami weapon on a torpedo for undersea delivery, nuclear-powered cruise missile) will exist to try to retain a credibile delivery platform for Russia’s nuclear deterrent in the face of US anti-ICBM stuff. The idea would be that if the US does a first strike on Russia, the US couldn’t necessarily intercept all of the response if the response includes unconventional delivery platforms.
EDIT: I’d also add that I’m skeptical that they’re going to be very reliable themselves as a counter to the US — I am very comfortable saying that if the US can shoot down fast-moving aircraft and counter submarines capable of firing depressed-trajectory SLBMs, that that it can probably manage to counter nuclear-powered cruise missiles and intercontinental nuclear torpedoes. Still, adding a new delivery platform might impose asymmetric costs on the US. Easier to develop a system that can shoot a bullet at someone than to develop one that can reliably shoot it out of the air mid-flight.
