I can’t vouch for the author at all, but this seems like a nice detailed, technical look at the difference between the two.
TL;DR the 212CD is very good at what in biology would be called “sit and wait predation”. It’s designed to sneak into an ocean floor crevice and hang out there, possibly for for weeks until something comes by, and then attack it. The Hanwha offering, on the other hand, is less superlatively stealthy and maneuverable, but is much more flexible, allowing missile launches and likely having a much longer range.
Ukraine made a deal with America to disarm back when America was a little trustworthy. Things have changed, and I say they’re good to resume nukes.
Close.Ukraine made a deal with Russia to return their nukes in exchange for non-invasion with US and European signatories as guarentors. (Because Russia has never been trustworthy.)
It’s why Nato supplying Ukraine is legitimate. Russia renegged on the non-invasion treaty knowing full well what happens.
Edit: Ukraine has no nuclear building capabilities in the short to medium term. Long term , who knows?
