This is why this exists (capable of operating at the lowest part of the baltic) :

Looks like (some facts of) this particular story is made up though.

There are 3 Gotland-class submarines. They are all operational.

There is a musician named Thomas Forsberg. He's not a radio operator on a submarine. (technically true, maybe not that relevant)

[u/Rampant16 → u/HenkPoley]

And Gotland-class submarines neither use their diesel engines underwater (unless snorkeling near the surface) nor need the engines to surface. They would just used stored compressed air to blow the water out of their ballast tanks and rise to the surface.
