I have a better idea: Turn the automated missile defense system back on.

That's too simple. What about Torpedoes and Iron Bombs. How come someone hasn't invented the force field bubble yet?
oops.... *dummy me*... It'd harm the marine life. :)

They tried that. They haven't figured out how to get the force field to stop forming at the water line. Force field surrounds ship, force field repels water around ship, ship drops to the bottom. Sad, really. Problem is, what they really need is a force field half-bubble. :-)
