PQ 17
PQ 17 was the code name for an Allies of World War II, Allied Arctic convoys, Arctic convoy during the Second World War. On 27 June 1942, the ships sailed from Hvalfjörður, Iceland, for the port of Arkhangelsk in the Soviet Union. The convoy was located by Nazi Germany, German forces on 1 July, after which it was shadowed continuously and attacked. The First Sea Lord Admiral Dudley Pound, acting on information that Kriegsmarine#Surface ships, German surface units, including the German battleship Tirpitz, German battleship ''Tirpitz'', were moving to intercept, ordered the covering force built around the Allied battleships HMS Duke of York (17), HMS ''Duke of York'' and the USS Washington (BB-56), USS ''Washington'' away from the convoy and told the convoy to scatter. Because of vacillation by ''Oberkommando der Wehrmacht'' (OKW, German armed forces high command), the ''Tirpitz'' raid never materialised. The convoy was the first large joint Anglo-American naval operation under Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Arkhangelsk

Midnight Sun
The midnight sun is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight. When the midnight sun is seen in the Arctic, the Sun appears to move from left to right, but in Antarctica the equivalent apparent motion is from right to left. This occurs at latitudes from 65°44' to 90° north or south, and does not stop exactly at the Arctic Circle or the Antarctic Circle, due to refraction. The opposite phenomenon, polar night, occurs in winter, when the Sun stays below the horizon throughout the day. Details Around the summer solstice (approximately 21 June in the Northern Hemisphere and 21 December in the Southern Hemisphere), in certain areas the Sun does not set below the horizon within a 24-hour period. Geography Because there are no permanent human settlements south of the Antarctic Circle, apart from research stations, the countries and territo ...

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] |
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 ...

USS Washington (BB-56)
USS ''Washington'' (BB-56) was the second and final member of the of fast battleships, the first vessel of the type built for the United States Navy. Built under the Washington Treaty system, ''North Carolina''s design was limited in displacement and armament, though the United States used a clause in the Second London Naval Treaty to increase the main battery from the original armament of nine guns to nine guns. The ship was laid down in 1938 and completed in May 1941, while the United States was still neutral during World War II. Her initial career was spent training along the East Coast of the United States until after Japan attacked Pearl Harbor on 7 December 1941, bringing the United States into the war. ''Washington'' was initially deployed to Britain to reinforce the Home Fleet, which was tasked with protecting convoys carrying supplies to the Soviet Union. She saw no action during this period, as the German fleet remained in port, and ''Washington'' was recalled to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Duke Of York (17)
HMS ''Duke of York'' was a battleship of the Royal Navy. Laid down in May 1937, the ship was constructed by John Brown and Company at Clydebank, Scotland, and commissioned into the Royal Navy on 4 November 1941, subsequently seeing combat service during the Second World War. In mid-December 1941, ''Duke of York'' transported Prime Minister Winston Churchill to the United States to meet President Franklin D. Roosevelt. The journey through the seas were rough even for the North Atlantic, Churchill wrote to his wife "Being in a ship in such weather as this is like being in a prison, with the extra chance of being drowned." Between March and September 1942 ''Duke of York'' was involved with convoy escort duties, including as flagship of the Heavy Covering Force of Convoy PQ-17, but in October she was dispatched to Gibraltar where she became the flagship of Force H. In October 1942, ''Duke of York'' was involved in the Allied invasion of North Africa, but saw little action as he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covering Force
A covering force is a military force tasked with operating in conjunction with a larger force, with the role of providing a strong protective outpost line (including operating in advance of the main force), searching for and attacking enemy forces or defending the main force from attack. The United States Army field manual "FM 3-90.6 Brigade Combat Team" provides the following definition of the role of a covering force: During World War II, the main body of the British Home Fleet regularly sortied into the Norwegian Sea to provide a heavy covering force to protect Arctic convoys from attack by German warships stationed in occupied Norway. The Battle of Driniumor River The Battle of Driniumor River, also known as the Battle of Aitape, 10 July – 25 August 1944, was part of the Western New Guinea campaign of World War II. During the fighting, Japanese forces launched several attacks on United States force ... also provides an example of a covering force action. References ...

German Battleship Tirpitz
''Tirpitz'' was the second of two s built for Nazi Germany's ''Kriegsmarine'' (navy) prior to and during the Second World War. Named after Grand Admiral Alfred von Tirpitz, the architect of the ''Kaiserliche Marine'' (Imperial Navy), the ship was laid down at the Kriegsmarinewerft Wilhelmshaven in November 1936 and her hull was launched two and a half years later. Work was completed in February 1941, when she was commissioned into the German fleet. Like her sister ship, , ''Tirpitz'' was armed with a main battery of eight guns in four twin turrets. After a series of wartime modifications she was 2000 tonnes heavier than ''Bismarck'', making her the heaviest battleship ever built by a European navy. After completing sea trials in early 1941, ''Tirpitz'' briefly served as the centrepiece of the Baltic Fleet, which was intended to prevent a possible break-out attempt by the Soviet Baltic Fleet. In early 1942, the ship sailed to Norway to act as a deterrent against an Allied inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kriegsmarine
The (, ) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic. 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-boat ...

Dudley Pound
Admiral of the Fleet Sir Alfred Dudley Pickman Rogers Pound, (29 August 1877 – 21 October 1943) was a British senior officer of the Royal Navy. He served in the First World War as a battleship commander, taking part in the Battle of Jutland with notable success, contributing to the sinking of the German cruiser . He served as First Sea Lord, the professional head of the Royal Navy, for the first four years of the Second World War. In that role his greatest achievement was his successful campaign against the German U-boats and the winning of the Battle of the Atlantic but his judgment has been questioned over the failed Norwegian Campaign in 1940, and his dismissal of Admiral Dudley North in 1940. His order in July 1942 to disperse Convoy PQ 17 and withdraw its covering forces, to counter a threat from heavy German surface ships, led to its destruction by submarines and aircraft. His health failed in 1943 and he resigned, dying shortly thereafter. Early life Born the son of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
