Butterfly Bomb
A Butterfly Bomb (or ''Sprengbombe Dickwandig 2 kg'' or SD 2) was a German anti-personnel submunition used by the Luftwaffe during the Second World War. It was so named because the thin cylindrical metal outer shell which hinged open when the bomblet deployed gave it the superficial appearance of a large butterfly. The design was very distinctive and easy to recognise. SD 2 bomblets were not dropped individually, but were packed into containers holding between 6 and 108 submunitions e.g. the AB 23 SD 2 and AB 250-3 submunition dispensers. The SD 2 submunitions were released after the container was released from the aircraft and had burst open. Because SD 2s were always dropped in groups (never individually) the discovery of one unexploded SD 2 was a reliable indication that others had been dropped nearby. This bomb type was one of the first cluster bombs ever used in combat and it proved to be a highly effective weapon. The bomb containers that carried the SD 2 bomblets and ...

Ipswich
Ipswich () is a port town and borough in Suffolk, England, of which it is the county town. The town is located in East Anglia about away from the mouth of the River Orwell and the North Sea. Ipswich is both on the Great Eastern Main Line railway and the A12 road; it is north-east of London, east-southeast of Cambridge and south of Norwich. Ipswich is surrounded by two Areas of Outstanding Natural Beauty (AONB): Suffolk Coast and Heaths and Dedham Vale. Ipswich's modern name is derived from the medieval name ''Gippeswic'', probably taken either from an Anglo-Saxon personal name or from an earlier name given to the Orwell Estuary (although possibly unrelated to the name of the River Gipping). It has also been known as ''Gyppewicus'' and ''Yppswyche''. The town has been continuously occupied since the Saxon period, and is contested to be one of the oldest towns in the United Kingdom.Hills, Catherine"England's Oldest Town" Retrieved 2 August 2015.

Thermos Bomb
''Thermos bomb'' was the informal name for the AR-4, an air dropped anti-personnel mine used by the Italian Air Force during World War II. Large numbers were used against Malta and in the Middle East. It was named for its superficial appearance to a Thermos bottle, a popular brand of vacuum flask. The bomb was a cylinder long and weighing . It could be fitted with a very sensitive motion-sensitive fuze that would detonate Detonation () is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with ... if any attempt was made to move it. It could be lethal in the open to approximately . Because of this, unexploded Thermos bombs were normally destroyed where they fell, either by attaching a long piece of string to them and giving it a jerk, or detonating a small explosive charge near them. A later variant of ...

M29 Cluster Bomb
The M29 cluster bomb was a cluster bomb used by the United States Air Force during World War II against troops, unarmoured vehicles and artillery. The weapon contained ninety M83 fragmentation submunitions - a direct copy of the earlier German Butterfly Bomb - in 9 ten-bomb "wafers". The M28 was a equivalent of the M29 containing 24 bomblets. Both bombs contained a mechanical time fuze that could be set to open the cluster at a preselected time between 5 and 92 seconds by triggering a burster charge. The case sides and ends sprung open, allowing the bomblets to fall out. The case sides were cup-shaped to retard the fall of the bomb. The manual warns that "Use of the M131 fuze is not recommended in areas that are expected to be occupied by friendly forces as they constitute a potential booby trap".

RAF Hornchurch
Royal Air Force Hornchurch or RAF Hornchurch is a former Royal Air Force sector station in the parish of Hornchurch, Essex (now the London Borough of Havering in Greater London), located to the southeast of Romford. The airfield was known as Sutton's Farm during the First World War, when it occupied of the farm of the same name. It was used for the protection of London, being east north-east of Charing Cross. Although the airfield closed shortly after the end of the war, the land was requisitioned in 1923 because of the expansion of the Royal Air Force and it re-opened as a much larger fighter station in 1928. The airfield was ideally to cover both London and the Thames corridor from German air attacks. It was a key air force installation between both wars and into the jet age, closing in 1962. History In 1915 the London Air Defence Area (LADA) was established and airfields were built around London to defend the capital from the growing threat from German airships. Sutton's ...

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed ''Schwalbe'' (German: "Swallow") in fighter versions, or ''Sturmvogel'' (German: "Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational jet-powered fighter aircraft. The initial design of what would become the Me 262 started in April 1939, prior to the start of the Second World War. While the aircraft performed its maiden flight on 18 April 1941, this was using piston engine instead of jet propulsion; it was not until 18 July 1942 that the first jet-powered flight was performed. Progress on the project was delayed by problems with engines, metallurgy and top-level interference from figures such as Hermann Göring, head of the Luftwaffe, and Adolf Hitler. The latter advocated from the Me 262 to be operated as a ground-attack/bomber aircraft rather than a defensive interceptor, thus necessitating a ...

Focke-Wulf Fw 190
The Focke-Wulf Fw 190, nicknamed ''Würger'' (" Shrike") is a German single-seat, single-engine fighter aircraft designed by Kurt Tank at Focke-Wulf in the late 1930s and widely used during World War II. Along with its well-known counterpart, the Messerschmitt Bf 109, the Fw 190 became the backbone of the (Fighter Force) of the . The twin-row BMW 801 radial engine that powered most operational versions enabled the Fw 190 to lift larger loads than the Bf 109, allowing its use as a day fighter, fighter-bomber, ground-attack aircraft and to a lesser degree, night fighter. The Fw 190A started flying operationally over France in August 1941 and quickly proved superior in all but turn radius to the Spitfire Mk. V, the main front-line fighter of the Royal Air Force (RAF), particularly at low and medium altitudes. The 190 maintained superiority over Allied fighters until the introduction of the improved Spitfire Mk. IX. In November/December 1942, the Fw 190 made its air combat ...

AB 250-2
The AB 250-2 (Abwurfbehälter) was a cluster bomb used by the Luftwaffe during World War II. AB 250-2 The body of the AB 250-2 was constructed of mild sheet steel and was of clamshell construction and hinged at the tail. It was divided into three compartments; a dome-shaped nose compartment, a cylindrical center compartment, and a cone-shaped tail compartment. The nose compartment housed the fuze pocket which was welded to a bracket on the upper half of the container. The two halves were held together by a shear wire which passed through a steel anvil, in the lower part of the fuze pocket. When the fuze is triggered, this wire was sheared by a small exploder under the fuze. The case then opened and allowed the bombs to fall out. The tail unit had four fins that were welded to the container with braces riveted between each fin. A number of different sub-munition configurations were possible: * 224 x SD 1 A or SD 1 FRZ - These were stored in the central compartment. The bombs w ...

Operation Barbarossa
Operation Barbarossa (german: link=no, Unternehmen Barbarossa; ) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. The operation, code-named after Frederick Barbarossa ("red beard"), a 12th-century Holy Roman emperor and German king, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories. Their ultimate goal was to create more (living space) for Germany, and the eventual extermination of the indigenous Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. In the two years leading up to the invasion, Nazi Germany and the Soviet Union signed political and economic pacts for st ...
