No. 172 Squadron RAF
No. 172 Squadron RAF was a Second World War Royal Air Force anti-submarine squadron that operated the Vickers Wellington equipped with the Leigh Light. History The squadron was formed on 4 April 1942 at RAF Chivenor from No. 1417 (Leigh Light) Flight, and was part of 19 Group, Coastal Command. The squadron had been formed to continue the work of the development flight to use the new Leigh Light in conjunction with ASV radar on anti-submarine patrols. The Leight Light was a powerful (22 million candles) searchlight used to illuminate the surface of the sea and any submarines caught on the surface. It operated from bases such as Malta, Gibraltar and the Azores to exploit the new invention and it was also used to attack surface vessels. The squadron re-equipped with the Wellington Mark XIII and the rate of sorties increased, although the aircraft losses also increased as they were hunted by German night-fighters in the Western Approaches. The Wellington Mk XIII and later XII a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heraldic Badges Of The Royal Air Force
Heraldic badges of the Royal Air Force are the insignia of certain commands, squadrons, units, wings, groups, branches and stations within the Royal Air Force. They are also commonly known as crests, especially by serving members of the Royal Air Force, but officially they are badges. Each badge must be approved by the reigning monarch of the time, and as such will either have a Tudor Crown (heraldry), King's or St Edward's Crown, Queen's Crown upon the top of the badge, dependent upon which monarch granted approval and the disbandment date of the unit.Most units/squadrons and bases had their badges updated to the Queen's Crown sometime after her accession, (although in some cases many years elapsed before the badge was updated). Most of the flying units were disbanded after the Second World War, so their badges retained the King's Crown. Queen Elizabeth II promulgated an order in October 1954 detailing that all current badges in use, and from that date on, were to use the Queen's ...

RAF Coastal Command
RAF Coastal Command was a formation within the Royal Air Force (RAF). It was founded in 1936, when the RAF was restructured into Fighter, Bomber and Coastal Commands and played an important role during the Second World War. Maritime Aviation had been neglected in the inter-war period, due to disagreements between the Royal Navy (RN) and RAF over the ownership, roles and investment in maritime air power. The Admiralty's main concern until 1937 was the return of the Fleet Air Arm to the Royal Navy while the RAF prioritised the development of a bombing force to provide a deterrent. Coastal Command was referred to as the "Cinderella Service" by A V Alexander, the First Lord of the Admiralty in November 1940. Soon after RAF Coastal Area was elevated to Coastal Command, its headquarters moved from Lee-on-Solent to Northwood in northwest London. During the Second World War, Coastal Command's most important contribution was the protection of Allied convoys from attacks by the Germ ...

Vickers Wellington
The Vickers Wellington was a British twin-engined, long-range medium bomber. It was designed during the mid-1930s at Brooklands in Weybridge, Surrey. Led by Vickers-Armstrongs' chief designer Rex Pierson; a key feature of the aircraft is its geodetic airframe fuselage structure, which was principally designed by Barnes Wallis. Development had been started in response to Air Ministry Specification B.9/32, issued in the middle of 1932, for a bomber for the Royal Air Force. This specification called for a twin-engined day bomber capable of delivering higher performance than any previous design. Other aircraft developed to the same specification include the Armstrong Whitworth Whitley and the Handley Page Hampden. During the development process, performance requirements such as for the tare weight changed substantially, and the engine used was not the one originally intended. The Wellington was used as a night bomber in the early years of the Second World War, performing as one o ... [...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] |
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".

Vickers Wellington At Lajes - Royal Air Force Coastal Command - No
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.

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] |
