Question: Who designed the German bomber which used the SC250 bomb to notable effect ?

full_context: Document 1: Messerschmitt Me 262: The Messerschmitt Me 262, nicknamed Schwalbe (German: "Swallow") in fighter versions, or Sturmvogel (German: "Storm Bird") in fighter-bomber versions, was the world's first operational jet-powered fighter aircraft. Design work started before World War II began, but problems with engines, metallurgy and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944. The Me 262 was faster and more heavily armed than any Allied fighter, including the British jet-powered Gloster Meteor. One of the most advanced aviation designs in operational use during World War II, the Me 262's roles included light bomber, reconnaissance and experimental night fighter versions.
Document 2: Junkers Ju 88: The Junkers Ju 88 was a German World War II "Luftwaffe" twin-engined multirole combat aircraft. Junkers Flugzeug- und Motorenwerke (JFM) designed the plane in the mid-1930s as a so-called "Schnellbomber" (fast bomber) that would be too fast for fighters of its era to intercept. It suffered from a number of technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war. Like a number of other "Luftwaffe" bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb.
Document 3: Ilyushin Il-2: The Ilyushin Il-2 (Cyrillic: Илью́шин Ил-2) Sturmovik was a ground-attack aircraft (Cyrillic: Штурмови́к, "Šturmovík") produced by the Soviet Union in large numbers during the Second World War. With 36,183 units of the Il-2 produced during the war, and in combination with its successor, the Ilyushin Il-10, a total of 42,330 were built, making it the single most produced military aircraft design in aviation history, as well as one of the most produced piloted aircraft in history along with the American postwar civilian Cessna 172 and the Soviet Union's own then-contemporary Polikarpov Po-2 "Kukuruznik" multipurpose biplane.
Document 4: Junkers Ju 87: The Junkers Ju 87 or Stuka (from "Sturzkampfflugzeug", "dive bomber") was a German dive bomber and ground-attack aircraft. Designed by Hermann Pohlmann, it first flew in 1935. The Ju 87 made its combat debut in 1937 with the Luftwaffe's Condor Legion during the Spanish Civil War and served the Axis forces in World War II.
Document 5: Stuka (disambiguation): Stuka, a German contraction of ""Sturzkampfflugzeug"" ("dive bomber") usually refers to the German Junkers Ju 87 dive bomber of World War II.
Document 6: Junkers: Junkers Flugzeug- und Motorenwerke AG (JFM, earlier JCO or JKO in World War I), more commonly Junkers, was a major German aircraft and aircraft engine manufacturer. It produced some of the world's most innovative and best-known airplanes over the course of its fifty-plus year history in Dessau, Germany. It was founded there in 1895 by Hugo Junkers, initially manufacturing boilers and radiators. During World War I, and following the war, the company became famous for its pioneering all-metal aircraft. During World War II the company produced some of the most successful Luftwaffe planes, as well as piston and jet aircraft engines, albeit in the absence of its founder, who had been removed by the Nazis in 1934.
Document 7: Butterfly Bomb: A Butterfly Bomb (or Sprengbombe Dickwandig 2 kg or SD2) was a German 2 kilogram 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. SD2 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 SD2 submunitions were released after the container was released from the aircraft and had burst open. Because SD2s were always dropped in groups (never individually) the discovery of one unexploded SD2 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 SD2 bomblets and released them in the air were nicknamed the "Devil's Eggs" by Luftwaffe air and ground crew.
Document 8: SC250 bomb: The SC 250 ("Sprengbombe Cylindrisch 250") was an air-dropped general purpose high-explosive bomb built by Germany during World War II and used extensively during that period. It could be carried by almost all German bomber aircraft, and was used to notable effect by the Junkers Ju 87 "Stuka" ("Sturzkampfflugzeug" or dive-bomber). The bomb's weight was about 250 kg, from which its designation was derived.
Document 9: Aichi D3A: The Aichi D3A Type 99 Carrier Bomber, (Allied reporting name "Val") was a World War II carrier-borne dive bomber. It was the primary dive bomber of the Imperial Japanese Navy (IJN), and participated in almost all IJN actions, including the attack on Pearl Harbor.
Document 10: Junkers Ju 187: The Junkers Ju 187 was a projected dive bomber designed to replace the ageing Junkers Ju 87 "Stuka". It was cancelled in 1943.
Document 11: Hermann Pohlmann: Hermann Pohlmann (26 June 1894 - 7 July 1991) was a German aerospace engineer and principal designer of the Junkers Ju 87 "Stuka", a dive bomber used during World War II.
Document 12: Heinkel He 118: The Heinkel He 118 was a prototype German monoplane dive bomber design that lost out to the Junkers Ju 87 "Stuka" in the 1930s, and was never ordered by the "Luftwaffe".
Document 13: Hugo Junkers: Hugo Junkers (3 February 1859 – 3 February 1935) was a German aircraft engineer and aircraft designer. As such, he is generally credited with pioneering the design of all-metal airplanes and flying wings. As founder of what would become the Junkers Flugzeug- und Motorenwerke AG following the First World War's armistice, he was one of the mainstays of the German aircraft industry in the years between World War I and World War II. In particular, his multi-engined all-metal passenger- and freight planes helped establish airlines in Germany, as well as all over the world. Although his name is also linked to some of the most successful German warplanes of the Second World War, Hugo Junkers himself had nothing to do with their development. He was forced out of his own company by the Nazi government in 1934 and died on his 76th birthday, in 1935.
Document 14: Savoia-Marchetti SM.85: The Savoia-Marchetti SM.85 was an Italian monoplane dive bomber and ground-attack aircraft that served in small numbers in the "Regia Aeronautica" at the beginning of World War II. They were soon replaced in service by the Junkers Ju 87.
Document 15: Kampfgeschwader 40: "Kampfgeschwader" 40 (KG 40) was a Luftwaffe medium and heavy bomber wing of World War II, and the primary maritime patrol unit of any size within the World War II Luftwaffe. It is best remembered as the unit operating a majority of the four-engine Focke-Wulf Fw 200 "Condor" maritime patrol bombers. The unit suffered from the poor serviceability and low production rates of the Fw 200 bombers, and from repeated diversion of its long-haul capability aircraft to undertake transport duties in various theatres, especially for the airlift operations to supply encircled forces in the Battle of Stalingrad. Later in the war, KG 40 became one of several Luftwaffe bomber wings to use the Heinkel He 177A heavy bomber.
