Warship: Life at Sea

Supposedly we are on the brink of war with Russia and have to go to search for a Sub threatening our communication lines in the North Atlantic. Well how did we know exactly where it was in the first place? In a supposedly tense scene in the second episode the sea states changed randomly and regularly along with the captains attire. Editor should consider a new career, if this was a film ( as it is styled) it would be ridiculous. Even the Navy ploughs it's frigate into a mountainous seas with only a rubber seal to protect its main gun. God help us if this is what is supposed to defend us.
