No Sandwich

Thatโ€™s probably the Dmitry Donskoy, the only one of the Typhoon-class still in active service. Three are already retired and two are laid up (this means they could be redeployed with fairly short notice).

That sub is 574 feet long, the largest submarine ever deployed. The new Columbia-class US subs will be nearly that long, at 560 feet.

Iโ€™m not sure about the concern about what happens to those subs if Russia collapses, though. Theyโ€™d sit in port, just like the others already are?
