While I'm far from a specialist, I suspect a nuclear detention on land delivered from a MIRV, which would each be in the Kt not Mt, wouldn't impact too much.
Well, likely, but also - if you can afford the extra safety...
See the reply from @Dylan Should answer your question
Not as thick as you'd think. It has to be baby (first year) ice (think 6ft for US boats, maybe 12 feet for the Russian Typhoon's)
I know what you mean but at the end of the day if a sub did fire off it’s nukes maybe the crew would survive but then there would be nothing to go home to once the inevitable retaliatory strikes went in. All pretty pointless really but that’s the game I suppose ?
Genuinely, why "the Ukraine"? This has probably been asked here before but still...
That's the general US take. MIRVs in the 80-ish kt range. With high CEP's they are incredibly accurate and can (and will, if needed) be used for pin-point surgical strikes on strategic targets. We stay away from the air-burst city busters these days (though they do still exist)
Don't get me wrong, nukes can wreak damage like no other, but I think thanks to movies people vastly over estimate the immediate damage. Even Tsar Bomba (the 50Mt weapon the Soviets tested) would flatten a city, and the pressure wave would travel for several miles killing a lot of people, they won't gouge out huge holes in the planet.
Well aware, but what I meant - maybe might be safer back in the water.
not sure. I know that the western Canadian province of Yukon is known as 'The Yukon' and has been for ages.
It means borderlands and saying "the ukraine" would've been normal... when they weren't a country.
A dear departed friend used to be away for months at a time secretly hiding under the ice sheets ready for, as he used to say, "the day Russia kick off."

A shockwave from a land based weapon wouldn't create any meaningful sub-surface wave. And even if it did, it wouldn't effect a sub in the slightest. The nuke would have to detonate underwater, i would probably say less than 10 miles from the sub for it to be a danger.....(though that is purely speculation, AFAIK it isn't something that has been tested (or at least release publicly))
