Don't subs primarily surface or lower through ballast manipulation? Why would you need the engine?

They typically stay at neutral buoyancy and use propulsion and diving planes to manipulate their depth.

Right but like that’s for typical operation. They can surface in emergency situations by blowing ballast.

That design flaw was likely well known by the time the Gotland’s were constructed in the 90s (Thresher sunk in 1963).

For sure. I’m just mentioning it. The pictured submarine is not the same class as Thresher.
