It depends but could be very difficult.
In daytime you have to surface at visual range of the ship, and prepare the gun to fire, it could take several seconds , enough time for the ship to use the radio .
In the case that your crew is very fast and can fire in seconds you still have to hit the radio at the first shot and know the exact place.

She is made of iron, sir. I assure you, she can. and she will. It is a mathematical certainty.
Strength and honor
