Would a nuclear torpedo be practical?

Question

Does anyone else think a nuclear or thermonuclear torpedo be practical and effective. Just think, while your submerged and safe you could fire just one at a Nimitz class Aircraft Carrier and watch it vaporise in the beautiful and spectacular explosion that is a mushroom cloud, instead of risking lots of planes and pilots with a bombing run or shooting hundreds of missiles.

It could just be a gun-assembly warhead since you don't really need 20 Megatons to destroy a carrier.

So anyone else think it would be practical to create a nuclear torpedo?

Answer 1

It is a cover story and US  military still likes to  vaporize cities instead.

Answer 2

The US had nuclear torpedoes at one time and the Russians still have them.

Answer 3

I guess it could work, but the Nimitz (and every other carrier in the fleet) carries anti-submarine aircraft and it has long range sonar, so the sub would be destroyed before it could get in range.

Answer 4

that would be a bit overkill don't you think

Answer 5

Could you fire it from 50 or 100 miles away?  That's the distance you would need to be to not get vaporised yourself. Maybe not such a great idea I think. The reason they used planes (long live Enola g*y) to deliver the bombs to Japan in WWII was because that was the fastest get away mechanism they had in those days. a Sub could not move away quickly enough.
