Operation Doppelschlag (Operation Double Blow/) was a German plan for a sortie in 1942 during the Second World War into the Arctic Ocean by the . The operation followed Operation Rösselsprung (1942), Operation Rösselsprung, against Convoy PQ 17 in July 1942 to attack convoy PQ 18 the next Arctic convoys of World War II, Arctic convoy of the Western Allies. Background Following the victory over Convoy PQ 17, the was keen to repeat the blow to assist German military operations. A plan was made to bring a strong force of capital ships and destroyers against the next supply convoy to destroy it. The commanders of the surface forces were disappointed they had been unable to take a more active part in the attack on PQ 17 and were determined to do better. The Allies wished to avoid running another convoy in the continuous daylight of the Midnight sun, Arctic summer and deferred passage of PQ 18 until later in the year. The German forces spent over two months at readiness before PQ 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sortie
A sortie (from the French word meaning ''exit'' or from Latin root ''surgere'' meaning to "rise up") is a deployment or dispatch of one military unit, be it an aircraft, ship, or troops, from a strongpoint. The term originated in siege warfare. In aviation In military aviation, a sortie is a combat mission of an individual aircraft, starting when the aircraft takes off. For example, one mission involving six aircraft would tally six sorties. The sortie rate is the number of sorties that a given unit can support in a given time. In siege warfare In siege warfare, the word ''sortie'' refers specifically to a sudden issuing of troops against the enemy from a defensive position—that is, an attack launched against the besiegers by the defenders. If the sortie is through a sally port, the verb ''to sally'' may be used interchangeably with ''to sortie''. Purposes of sorties include harassment of enemy troops, destruction of siege weaponry and engineering works, joining the relief ...

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] |
Battle Of The Barents Sea
The Battle of the Barents Sea was a World War II naval engagement on 31 December 1942 between warships of the German Navy (''Kriegsmarine'') and British ships escorting convoy JW 51B to Kola Inlet in the USSR. The action took place in the Barents Sea north of North Cape, Norway. The German raiders' failure to inflict significant losses on the convoy infuriated Hitler, who ordered that German naval strategy would henceforth concentrate on the U-boat fleet rather than surface ships. Background JW 51B Convoy JW 51B comprised fourteen merchant ships carrying war materials to the USSR — some 202 tanks, 2,046 vehicles, 87 fighters, 33 bombers, of fuel, of aviation fuel and just over of other supplies. They were protected by the destroyers , , , , and ; the s and ; the minesweeper ; and trawlers and . The escort commander was Captain Robert Sherbrooke RN (flag in ''Onslow'').

Convoy JW 51B
Convoy JW 51B was an Arctic convoy sent from United Kingdom by the Western Allies to aid the Soviet Union during World War II. It sailed in late December 1942, reaching the Soviet northern ports in early January 1943. JW 51B came under attack by German surface units, engaged in Operation Regenbogen, on 31 December. In the clash that ensued, one defending minesweeper and one attacking destroyer were sunk with all hands and a defending destroyer was sunk; no ships were lost from the convoy. This engagement became known as the Battle of the Barents Sea. Forces JW 51A consisted of 15 merchant ships which departed from Loch Ewe on 22 December 1942. Close escort was provided by the minesweeper , two corvettes and two armed trawlers. The close escort was supported by six Home Fleet destroyers led by (Capt Robert Sherbrooke commanding).

Operation Regenbogen (Arctic)
Operation Regenbogen (Operation Rainbow) was a sortie in 1942 into the Arctic Ocean by warships of the Nazi Germany (German navy) during the Second World War. The operation culminated in the Battle of the Barents Sea. Background Following the hard-fought PQ 18 and the disastrous PQ 17 battles in the autumn and summer of 1942 the Allied supply convoys to the Soviet Union had been temporarily suspended. In December 1942 they started again with a new JW/RA convoy series. Against this possibility the had concentrated a large force of surface vessels and U-boats, supported by aircraft from the (German Air Force). German plan was based on a plan to intercept the next Allied convoy to Murmansk. A patrol line of four U-boats was established off Bear Island and a surface force consisting of cruisers ''Hipper'', ''Lützow'' and six destroyers was assembled at Altafjord. In the event of a convoy report the fleet would sail as two battle-groups; one to engage the expected cruiser e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The was one of three official branches, along with the and the , of the , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines (U-boats ...

Luftwaffe
The ''Luftwaffe'' () was the aerial-warfare branch of the German ''Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the ''Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabteilung'' of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the ''Luftwaffe''s existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a ''Luftwaffe'' detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing grou ...

Norwegian Sea
The Norwegian Sea ( no, Norskehavet; is, Noregshaf; fo, Norskahavið) is a marginal sea, grouped with either the Atlantic Ocean or the Arctic Ocean, northwest of Norway between the North Sea and the Greenland Sea, adjoining the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe Islands. To the north, the Jan Mayen Ridge separates it from the Greenland Sea. Unlike many other seas, most of the bottom of the Norwegian Sea is not part of a continental shelf and therefore lies at a great depth of about two kilometres on average. Rich deposits of oil and natural gas are found under the sea bottom and are being explored commercially, in the areas with sea depths of up to about one kilometre. The coastal zones are rich in fish that visit the Norwegian Sea from the North Atlantic or from the Barents Sea (cod) for spawning. The warm North Atlantic Current ensures relatively stable and high wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
