It you have a few bucks to spare, you can buy this private submarine for $2 Billion. It is about 265 feet long, can sink to about a thousand feet and stay under water for 10 days at a time.
Probably enough to outlast the initial effects of the nuclear war we are about to have with Russia.
I want one.
$2 billion private submarine concept has a helipad and can lurk underwater for weeks
