Rocket U-boat
The Rocket U-boat was a series of military projects undertaken by Nazi Germany during the Second World War. The projects, which were undertaken at Peenemünde Army Research Center, aimed to develop submarine-launched rockets, flying bombs and missiles. The German Navy did not use submarine-launched rockets or missiles from U-boats against targets at sea or ashore. These projects never reached combat readiness before the war ended. From May 31 to June 5, 1942, a series of underwater-launching experiments of solid-fuel rockets were carried out using submarine as a launching platform. The rocket system was first envisaged as a weapon against convoy escorts but with no effective guidance system, the arrangement was ineffective against moving targets and could only be used for shore bombardment. Development of this system ended in early 1943 because it decreased the U-boats' seaworthiness. Plans for the rocket U-boat involved an attack on New York City using newly invented V-2 ro ...

V2 U-boat Rocket
V, or v, is the twenty-second and fifth-to-last letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''vee'' (pronounced ), plural ''vees''. History The letter V ultimately comes from the Phoenician letter ''waw'' by way of U. See U for details. During the Late Middle Ages, two minuscule glyphs of U developed which were both used for sounds including and modern . The pointed form "v" was written at the beginning of a word, while a rounded form "u" was used in the middle or end, regardless of sound. So whereas "valour" and "excuse" appeared as in modern printing, "have" and "upon" were printed as "haue" and "vpon". The first distinction between the letters "u" and "v" is recorded in a Gothic script from 1386, where "v" preceded "u". By the mid-16th century, the "v" form was used to represent the consonant and "u" the vowel sound, giving us the modern letter V. ...

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...

The Blitz
The Blitz was a German bombing campaign against the United Kingdom in 1940 and 1941, during the Second World War. The term was first used by the British press and originated from the term , the German word meaning 'lightning war'. The Germans conducted mass air attacks against industrial targets, towns, and cities, beginning with raids on London towards the end of the Battle of Britain in 1940 (a battle for daylight air superiority between the Luftwaffe and the Royal Air Force over the United Kingdom). By September 1940, the Luftwaffe had lost the Battle of Britain and the German air fleets () were ordered to attack London, to draw RAF Fighter Command into a battle of annihilation.Price 1990, p. 12. Adolf Hitler and Reichsmarschall Hermann Göring, commander-in-chief of the Luftwaffe, ordered the new policy on 6 September 1940. From 7 September 1940, London was systematically bombed by the Luftwaffe for 56 of the following 57 days and nights. Most notable was a large dayligh ...

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 ...

Coventry Blitz
The Coventry Blitz (blitz: from the German word ''Blitzkrieg'' meaning "lightning war" ) or Coventration of the city was a series of bombing raids that took place on the British city of Coventry. The city was bombed many times during the Second World War by the German Air Force (''Luftwaffe''). The most devastating of these attacks occurred on the evening of 14 November 1940 and continued into the morning of 15 November. Background At the start of the Second World War, Coventry was an industrial city of around 238,000 people which, like much of the industrial West Midlands, contained metal and wood-working industries. In Coventry's case, these included cars, bicycles, aeroplane engines and, since 1900, munitions factories. In the words of the historian Frederick Taylor, "Coventry was therefore, in terms of what little law existed on the subject, a legitimate target for aerial bombing". During the First World War, the advanced state of the mechanical tooling indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Incendiary Bomb
Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires or destroy sensitive equipment using fire (and sometimes used as anti-personnel weaponry), that use materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often known as bombs, they are not explosives but in fact are designed to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm for example, is petroleum especially thickened with certain chemicals into a 'gel' to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression. Pre-modern history A range of early thermal weapons were utilized by ancient, medieval/post-classical and early modern armies, including hot pitch, oil, resin, animal fat and other similar compounds.

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".
