Butterfly Bomb
The Butterfly Bomb (or ''Sprengbombe Dickwandig 2 kg'' or SD 2) was a German anti-personnel submunition (or ''bomblet'') 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 ...

M29 Cluster Bomb
M, or m, is the thirteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of several western European languages and others worldwide. Its name in English is ''em'' (pronounced ), plural ''ems''. History The letter M is derived from the Phoenician Mem via the Greek Mu (Μ, μ). Semitic Mem is most likely derived from a " Proto-Sinaitic" (Bronze Age) adoption of the "water" ideogram in Egyptian writing.

Fighter-bomber
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles. Although still used, the term fighter-bomber has less significance since the introduction of rockets and guided missiles into aerial warfare. Modern aircraft with similar duties are now typically called multirole combat aircraft or strike fighters. Development Prior to World War II, general limitations in available Aircraft engine, engine and Aerospace engineering, aeronautical technology required that each proposed military aircraft have its design tailored to a specific prescribed role. Reciprocating engine, Engine power grew dramatically during the early period of the war, roughly doubling between 1939 and 1943. The Bristol Blenheim, a typical ...

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed (German for "Swallow") in fighter versions, or ("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 and one of two jet fighter aircraft types to see air-to-air combat in World War Two, the other being the Heinkel He 162.

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 Supermarine Spitfire (early Merlin-powered variants)#Mk V (Mk V (Types 331, 349 and 352)), Spitfire Mk. V, the main front-line fighter of the Royal Air Force (RAF), particularly at low and medium altitudes. The 190 maintained its superiority over Allies of World War II, Allied fighters until ...

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 ...
