Not like an aircraft, but HMS Dreadnought was the only submarine in the world that could achieve the phenomenon whilst on the surface - due to its unique shape.
The order was “bring the plant to the full power state, uncotter 3,4 and 5 main ballast tank vents”
Whilst winding on max revs for surface running, 10 degrees of rise were set on the foreplanes and aft planes, open aft main vents for ten seconds to dig the stern in.
At a certain speed, with the reactor at 100% the boat would rise up forward and settle stern down putting up a 12ft high wake - semi-submerged but still maintaining positive buoyancy.
Then, the magic happened - at 23knots the reactor power would reduce on its own and settle at 70%. Accordingly, it was deemed our most economical speed !
I’ll leave the experts to work out how it could happen.
Incidentally, it must be the only power driver that can operate at full chat and remain totally silent - if you could stand beside it. Access over the reactor compartment is via a shielded tunnel.

Antagonise no man, for you never know the hour when you may have need of him.
