When a torpedo starts coming straight at you, there’s only one thing a submarine crew can do – snap into “full evasion” mode. Captain Ryan Ramsey issues swift orders. His crew responds immediately, twisting the Royal Navy’s Trafalgar-class submarine to manoeuvre the boat beneath the waves in an effort to shake off the weapon bearing down fast on their position.
It would, though, take a miracle for a submarine of nearly 6,000 tons to outrun a torpedo. And that miracle never comes. The torpedo smashes into the fin, the large central structure on the submarine sometimes called the conning tower. As it hits the boat, a loud bang reverberates hard through the hull, a high-strength steel alloy designed to withstand the extreme pressure experienced at the submarine’s maximum – and classified – diving depth.
