The author is not very familiar with how subs work. They are the concealed weapon of international politics. The only way a hostile should find out if a sub is in the area is when it “detects by detonation”.

I'm thinking this is why the old guy suggested a nuke sub. The Argentinians would think twice before sending ships into an area where there might be subs.
