Sweden: Another near-miss in Baltic skies

14. The worst ones are submerged!

Your other photos also looks like decommissioned subs to me. Old ones from Soviet time. Russia has hundreds of these old rusty ones parked everywhere, and only a few of them has mostly voluntary caretakers keeping them alive for fun.

The very worst place are at the Barents Sea, where many of the nuclear ones has just been cut in half, and the reactor core just left at the bottom of the sea up there.

That is real stuff to be scared of.

Remember that Russian only uses less than ten percent of what NATO spends on the military, and that was before they lost the main part of income from their oil, on top of the international sanctions. Russia are lacking money for everything.
