Submarine U-14 (LOC) (6358166395)
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convoy HX 79
HX 79 was an Allied North Atlantic convoy of the HX series which ran during the Battle of the Atlantic in World War II. It suffered major losses from a U-boat attack, and, with the attack on convoy SC 7 the previous day, represents the worst two days shipping losses in the entire Atlantic campaign. Prelude HX 79 was an east-bound convoy of 50 ships which sailed from Halifax on 8 October 1940 making for Liverpool. On 19 October, 4 days from landfall, HX 79 was entering the Western Approaches, and had caught up with the position of SC 7, which was under attack. The escort for the crossing had been meagre, being provided by two armed merchant cruisers against the possibility of attack by a surface raider, but these had departed when HX 79 was sighted by , commanded by ''Kapitänleutnant'' Günther Prien. At this point HX 79 was unescorted; Prien sent a sighting report and set to shadowing the convoy, while ''Konteradmiral'' Karl Dönitz ordered the pack to assemble. Those U-b ...

Convoy SC 7
SC 7 was the code name for a large Allied World War II convoy of 35 merchant ships and six escorts, which sailed eastbound from Sydney, Nova Scotia, for Liverpool and other United Kingdom ports on 5 October 1940. While crossing the Atlantic, the convoy was intercepted by one of the first ''Kriegsmarine'' submarine wolfpacks. During the ensuing battle, the escort was completely overwhelmed and 20 of the 35 cargo vessels were sunk and 2 more damaged, with 141 lives lost. The disastrous outcome of the convoy demonstrated the German submarines' potential of being able to work more efficiently using wolfpack tactics and the inadequacy of British anti-submarine tactics at the time. Ships of the convoy The slow convoy SC 7 left Sydney, Nova Scotia on 5 October 1940 bound for Liverpool and other British ports. The convoy was supposed to make but several merchant ships were much slower, necessitating a further reduced speed. The convoy consisted of older, smaller ships, mostly with ...

Joachim Schepke
Joachim Schepke (8 March 1912 – 17 March 1941) was a German U-boat commander during World War II. He was the seventh recipient of the Knight's Cross of the Iron Cross with Oak Leaves. Schepke is credited with having sunk 36 Allied ships. During his career, he gained notoriety among fellow U-boat commanders for exaggerating the tonnage of ships sunk. Career Schepke joined the ''Reichsmarine'' in 1930. In 1934, he was assigned to the newly created U-boat arm, and in 1938 he commanded . After a short stint commanding and serving in a staff position, Schepke received the command of , a Type VIIB boat.

Günther Prien
Günther Prien (16 January 1908 – presumed 8 March 1941) was a German U-boat commander during World War II. He was the first U-boat commander to receive the Knight's Cross of the Iron Cross and the first member of the ''Kriegsmarine'' to receive the Knight's Cross of the Iron Cross with Oak Leaves of Nazi Germany. It was Germany's highest military decoration at the time of its presentation to Prien. Under Prien's command, the submarine was credited with sinking over 30 Allied ships totalling about , along with the British battleship at anchor in the Home Fleet's anchorage in Scapa Flow. Early life and career Prien was one of three children of a judge and completed his basic education. At the age of five, Prien had been living with relatives, the notary Carl Hahn and his wife, in Lübeck. There he attended the Katharineum, a humanistic secondary school.

Otto Kretschmer
Otto Kretschmer (1 May 1912 – 5 August 1998) was a German naval officer and submariner in World War II and the Cold War. From September 1939 until his capture in March 1941 he sank 44 ships, including one warship, a total of 274,333 tons. For this he received the Knight's Cross of the Iron Cross with Oak Leaves and Swords, among other awards. He earned the nickname "Silent Otto", both for his successful use of the " silent running" capability of U-boats and for his reluctance to transmit radio messages during patrols. After the war he served in the German Federal Navy, from which he retired in 1970 with the flag rank of commodore. Early life and career Kretschmer was born in Heidau near Neisse, then in the German Empire on 1 May 1912 to Friedrich Wilhelm Otto and Alice (née Herbig) Kretschmer. His father was a teacher at the local ''Volkschule'' (primary school), which Otto attended from 1918 to 1921. He then moved to a ''Realgymnasium'' ( secondary school). In the aftermath ...

Wolfpack (naval Tactic)
The wolfpack was a convoy attack tactic employed in the Second World War. It was used principally by the U-boats of the during the Battle of the Atlantic, and by the submarines of the United States Navy in the Pacific War. The idea of a co-ordinated submarine attack on convoys had been proposed during the First World War but had no success. In the Atlantic during the Second World War the Germans had considerable successes with their wolfpack attacks but were ultimately defeated by the Allies. In the Pacific the American submarine force was able to devastate Japan’s merchant marine, though this was not solely due to the wolfpack tactic. Wolfpacks fell out of use during the Cold War as the role of the submarine changed and as convoys became rare. World War I During the (German war on trade) Allied ships travelled independently prior to the introduction of the convoy system and were vulnerable to attacks by U-boats operating as 'lone wolves'. By gathering up merchant ships into con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
