old diesel u-boat vs modern navy comedy exercise

Maverick Navy Lieutenant Commander Tom Dodge will never be a textbook officer, but he's a brilliant seaman who's always wanted to command a nuclear submarine — he's been given one last chance to clean up his record. Unfortunately, Admiral Graham, his nemesis, would rather sink the fleet than give Dodge his own boat. So, Graham stacks the deck against him and assigns Dodge to the Stingray, a diesel-powered WW2 submarine that can barely keep afloat. To make matters worse, Dodge's crew is a collection of maladjusted, mistake-prone misfits. Then, he's tagged the "enemy" in a crucial war game, and ordered to take on the U.S. Navy's best.

The East German Navy's newest submarine hunter is presented. Also, a historical excursus about older anti-submarine ships and the hunt for enemy submarines is shown.

January 1943: Admiral Karl Dönitz, head of the Nazis’ U-boat fleet, has brought Britain to the brink of starvation by ruthlessly destroying close to a thousand of their merchant ships. If the transatlantic shipping route is cut off, the Allies will lose their last foothold in Western Europe. The Royal Navy turns to retired war gamer Gilbert Roberts. Roberts is to use war gaming to try to decipher and combat Dönitz’s tactics. To do this, he needs a team, but the Navy can’t spare any men. Instead, he risks the ridicule of high command by turning to the Women’s Royal Navy Service (WRNS) to war game the U-boats’ tactics. In partnership with Jean Laidlaw, one of Britain’s first female chartered accountants, and a small team of resourceful female mathematicians, Roberts acts out naval battles and games the U-boats’ moves on a linoleum floor, using chalk and wooden model ships.

While war was raging on land a whole new breed of war was being waged in the oceans of the world. The German submarine U-Boat threat was a dangerous game of sink or swim against British and American forces. From convoys to merchants the battle saw over 100,000 lives lost at sea in a brutal and terrifying new kind of warfare.
