This makes absolutely no sense..

Yes the Submarine is like an Airplane with the Diveplanes in the sense that they "drive" the Submarine to a lower depth. Just as an Aircrafts Ailerons, Rudder and Elevators help it achieve its altitude.

The difference between a Submarine and an Aircraft though is that the Aircraft needs to be constantly moving at a certain speed and angle of attack to keep flight.

The submarine needs lower speeds (obviously it cannot reach the same speeds as an aircraft but in perspective). And has the advantage of buoyancy. If a submarine is badly trimmed and has negative or positive trim then it will have to keep up a higher speed and make more use of its dive planes.. if it has neutral buoyancy then all it needs to do is maintain steerageway so that the helm does not lose control..
