Unlikely seems such a strong word when, as you say, the laws of physics are applied to something unique, big and moving. Newton's third law ensures that a submarine's interaction with water will always have an effect.
If someone had mentioned using radar to look for the disturbance caused by a submerged contact 20 years ago I would have laughed. Moore's Law has already sucked away all remaining humour from this concept.
Having failed to see this coming I am clearly not ready to predict what will happen over the next 20 years....
