Wunderwaffen
''Wunderwaffe'' () is German word meaning "wonder-weapon" and was a term assigned during World War II by Nazi Germany's propaganda ministry to some revolutionary "superweapons". Most of these weapons however remained prototypes, which either never reached the combat theater, or if they did, were too late or in too insignificant numbers to have a military effect. The V-weapons, which were developed earlier and saw considerable deployment, especially against London and Antwerp, trace back to the same pool of highly inventive armament concepts. Therefore, they are also included here. As the war situation worsened for Germany from 1942, claims about the development of revolutionary new weapons which could turn the tide became an increasingly prominent part of the propaganda directed at Germans by their government. In reality, the advanced weapons under development generally required lengthy periods of design work and testing, and there was no realistic prospect of the German milit ...

H-class Battleship Proposals
The H class was a series of battleship designs for Nazi Germany's ''Kriegsmarine'', which were intended to fulfill the requirements of Plan Z in the late 1930s and early 1940s. The first variation, "H-39," called for six ships to be built, essentially as enlarged s with guns and diesel propulsion. The "H-41" design improved the "H-39" ship with still larger main guns, eight weapons, and reinforced deck armor. The Construction Office of the ''Oberkommando der Marine'' (''OKM'') concluded their work with the "H-41" design, and were not involved in subsequent plans. Two of them, "H-42" and "H-43", increased the main battery yet again, with pieces, and the enormous "H-44" design ultimately resulted with guns. The ships ranged in size from the "H-39", which was long on a displacement of , to the "H-44", at on a displacement of . Most of the designs had a proposed top speed in excess of . Due to the outbreak of World War II in September 1939, none of the ships were ever completed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tallboy (bomb)
Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War."Medium capacity" refers to the ratio of bomb case to explosive filling; in the case of the Tallboy, this was less than 50 per cent explosive by weight, in contrast to "high capacity" bombs like the Blockbuster bombs, in which up to three-quarters of their weight was the explosive. At , it could be carried only by a modified model of the Avro Lancaster heavy bomber. It proved to be effective against large, fortified structures against which conventional bombing had proved ineffective. History Wallis presented his ideas for a 10-ton bomb in his 1941 paper "A Note on a Method of Attacking the Axis Powers", which showed that a very large bomb exploding deep underground next to a target would transmit the shock into the foundations of the target, particularly since shock waves are trans ...

Blockbuster Bomb
A blockbuster bomb or cookie was one of several of the largest conventional bombs used in World War II by the Royal Air Force (RAF). The term ''blockbuster'' was originally a name coined by the press and referred to a bomb which had enough explosive power to destroy an entire street or large building through the effects of blast in conjunction with incendiary bombs. Design The bombs then called ''Blockbusters'' were the RAF's HC (high capacity) bombs. These bombs had especially thin casings that allowed them to contain approximately three-quarters of their weight in explosive, with a 4000 lb bomb (nominal weight) containing about of explosive (Amatol, RDX or Torpex). Most general-purpose bombs, termed "medium capacity'" (MC) by the RAF, contained 50% explosive by weight, the rest being made up of the fragmentation casing. Larger Blockbusters were made later in the war, from the original version, up to . The 4000 lb High Capacity Mark I bomb – actual weight around – was ...

Avro Lancaster
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive-bombing attacks. Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one of the versions, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic bom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF Bomber Command
RAF Bomber Command controlled the Royal Air Force's bomber forces from 1936 to 1968. Along with the United States Army Air Forces, it played the central role in the strategic bombing of Germany in World War II. From 1942 onward, the British bombing campaign against Germany became less restrictive and increasingly targeted industrial sites and the civilian manpower base essential for German war production. In total 364,514 operational sorties were flown, 1,030,500 tons of bombs were dropped and 8,325 aircraft lost in action. Bomber Command crews also suffered a high casualty rate: 55,573 were killed out of a total of 125,000 aircrew, a 44.4% death rate. A further 8,403 men were wounded in action, and 9,838 became prisoners of war. Bomber Command stood at the peak of its post-war military power in the 1960s, the V bombers holding the United Kingdom's nuclear deterrent and a supplemental force of Canberra light bombers. In August 2006, a memorial was unveiled at Lincoln Cathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Torpedo Bomber
A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous Second World War battles, notably the British attack at Taranto, the sinking of the German battleship ''Bismarck'', and the Japanese attack on Pearl Harbor. Types Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedoes specifically designed for air launch, which were smaller and lighter than those used by submarines and surface warships. Nonetheless, as an airborne torpedo could weigh as much as , more than twice the bomb load of contemporary single-engined bombers, the aircraft carrying it usually needed to be specially designed ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last Battle Of The Battleship Bismarck
The last battle of the German battleship ''Bismarck'' took place in the Atlantic Ocean approximately west of Brest, France, on 26–27 May 1941 between the and naval and air elements of the British Royal Navy. Although it was a decisive action between capital ships, it has no generally accepted name. On 24 May, before the final action, ''Bismarck''s fuel tanks were damaged and several machinery compartments, including a boiler room, were flooded in the Battle of the Denmark Strait. Her captain's intention was to reach the port of Brest for repair. Late in the day ''Bismarck'' briefly turned on her pursuers ( and the heavy cruisers and ) to cover the escape of her companion, the heavy cruiser to continue further into the Atlantic. Early on 25 May the British forces lost contact with ''Bismarck'', which headed ESE towards France while the British searched northeast, presuming she was returning to Norway. Later on 25 May the commander of the German force, Admiral Günther Lü ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Battleship Bismarck
''Bismarck'' was the first of two s built for Nazi Germany's . Named after Chancellor Otto von Bismarck, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. ''Bismarck'' and her sister ship were the largest battleships ever built by Germany, and two of the largest built by any European power. In the course of the warship's eight-month career, ''Bismarck'' conducted only one offensive operation that lasted 8 days in May 1941, codenamed . The ship, along with the heavy cruiser , was to break into the Atlantic Ocean and raid Allied shipping from North America to Great Britain. The two ships were detected several times off Scandinavia, and British naval units were deployed to block their route. At the Battle of the Denmark Strait, the battlecruiser initially engaged ''Prinz Eugen'', probably by mistake, while engaged ''Bismarck''. In the en ...

Yamato-class Battleship
The were two battleships of the Imperial Japanese Navy (IJN), and , laid down leading up to World War II and completed as designed. A third hull laid down in 1940 was converted to an aircraft carrier, , during construction. Displacing nearly at full load, the completed battleships were the heaviest ever constructed. The class carried the largest naval artillery ever fitted to a warship, nine 460-mm (18.1 in) naval guns, each capable of firing shells over . Due to the threat of U.S. submarines and aircraft carriers, both ''Yamato'' and ''Musashi'' spent the majority of their careers in naval bases at Brunei, Truk, and Kure—deploying on several occasions in response to U.S. raids on Japanese bases. All three ships were sunk by the U.S. Navy; ''Musashi'' while participating in the Battle of Leyte Gulf in October 1944, the ''Shinano'' while under way from Yokosuka to Kure for fitting out in November 1944, and the ''Yamato'' while en route from Japan to Okinawa as pa ...
