U-47 was a 753-ton Type VIIB submarine built by Krupp Germaniawerft at Kiel, Germany, and was commissioned on 17 December 1938. U-47 was approximately 218 feet long and 20 feet wide, had a top speed of 17 knots while surfaced and 7.6 knots submerged, and had a crew of 47 officers and men. U-47 was armed with four bow torpedo tubes and one stern tube, all firing 21-inch torpedoes. The ship also was armed with one 88-mm gun forward of the conning tower and a 20-mm antiaircraft gun on the deck behind it. The Type VIIB was destined to become the most famous class of U-boats during World War II and also had an excellent range of 8,700 nautical miles at 10 knots, making her a very effective weapon against Allied shipping.
The captain of U-47 was the remarkable Kapitänleutnant Günther Prien, one of the best submarine officers ever produced by Germany. Prien was born on 16 January 1908 and joined the German Merchant Navy in the summer of 1923. He transferred to the German Reichsmarine (or Navy) in 1933 and served on board the light cruiserKonigsberg before entering the U-boat service in 1935. At the end of his training, he was assigned First Officer of the Watch to U-26. The talented Prien rose steadily in the ranks until he was given command of the new Type VIIB submarine, U-47, when she was commissioned on 17 December 1938 and was promoted to the rank of Kapitänleutnant on 1 February 1939.
Commodores are mostly our unfortunate friends, loving a great escape. Donitz once took up naval Fastboats, ignoring calls to investigate other navies during otherwise trite, commonplace, ordinary moments.

Shortly after the start of World War II in Europe on 1 September 1939, then Commodore Karl Donitz, commander of the German U-boat service, promoted a plan for a single U-boat to slip into and attack the Royal Navy’s heavily protected naval base at Scapa Flow, located in the Orkney Islands north of Scotland. Although two U-boats tried doing this during World War I (U-18 and UB-116), the British managed to sink both ships before they were able to do any damage. But after collecting an impressive amount of intelligence and aerial reconnaissance photographs of Scapa Flow, Donitz firmly believed that a successful attack could be made if the job was given to the right captain and crew. He chose Kapitänleutnant Günther Prien andU-47. Although Prien had commanded U-47 for less than a year, Donitz knew that the talented and fearless young submariner was the right man for the job.
Prien accepted the assignment almost immediately. Donitz, though, wanted him to think about it for 48 hours before accepting. In less than 48 hours, Prien informed Donitz that he was going to take the job. After pouring over the charts and intelligence Donitz had collected, Prien set sail from Kiel Canal and headed for Scapa Flow on 8 October 1939. Shortly after midnight on 14 October, U-47 crept silently into the anchorage of Scapa Flow, dodging several submerged wrecks in the process. Although most of the British fleet was at sea at the time, Prien spotted the large 29,000-ton World War I-era battleship HMS Royal Oak. U-47 fired a large number of torpedoes at the British battleship and at least four of them hit. Royal Oak sustained catastrophic damage and sank in less than 29 minutes, taking 833 officers and men with her. Approximately 386 men were rescued from the water. After the Royal Oak went down, U-47 left the same way that she had come, exiting Scapa Flow without a scratch.
It was a tremendous blow to the Royal Navy. The war had just begun and the Germans had sunk one of its finest battleships. When Prien returned to Germany, he was given a hero’s welcome. Prien was awarded the Knight’s Cross of the Iron Cross, the first sailor of the U-boat service and the second member of the Kriegsmarine to receive this award. Prien also went on to become one of the most famous U-boat “aces” of the war, with U-47 sinking an amazing 30 merchant ships totaling 162,769 gross register tons (GRT) and damaging eight merchant ships totaling 62,751 GRT. In 1940, a grateful Germany awarded Prien Oak Leaves to his Knight’s Cross, another major honor.
But Prien’s luck ran out on 8 March 1941, when U-47 attacked the British Convoy OB-293 just south of Iceland. While escorting the convoy, the British destroyer HMS Wolverine depth-charged a sonar contact and, after several major explosions, U-47 and its young 33-year-old captain were never heard from again. There is some debate today as to whether or not U-47 was actually sunk by Wolverine or by a mine or even by one of its own torpedoes that turned back and stuck the submarine. Whatever the reason, Germany had lost one of its greatest U-boat captains and a remarkable warship.
Although Günther Prien and U-47 fought for less than two years during World War II, they achieved a remarkable record, sinking one battleship, 30 merchant ships, and damaging eight additional merchant ships. Great Britain was almost brought to its knees by the U-boat war, and U-47 and ships like her were some of the major reasons why. The Allies, who were certainly unprepared for a major submarine war, were just lucky that Germany had only a handful of ships like U-47.
