Question: The unit formed in 1936 featured what type of aircraft designed by Siegfried and Walter Gunter?

full_context: Document 1: Jagdgeschwader 70: "Jagdgeschwader" 70 was a fighter wing of Nazi Germany's Luftwaffe in World War II.
Document 2: 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 3: 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.
Document 4: Heinkel He 112: The Heinkel He 112 is a German fighter aircraft designed by Walter and Siegfried Günter. It was one of four aircraft designed to compete for the Luftwaffe's 1933 fighter contract, in which it eventually came second behind the Messerschmitt Bf 109. Small numbers were used for a short time by the Luftwaffe, and small runs were completed for several other countries, but only around 100 were completed in total.
Document 5: Jagdgeschwader 52: "Jagdgeschwader" 52 (JG 52) (52nd Fighter Wing) of the Luftwaffe, was the most successful fighter-wing of all time, with a claimed total of more than 10,000 victories over enemy aircraft during World War II. It was the unit of the top three scoring flying aces of all time, Erich Hartmann, Gerhard Barkhorn and Günther Rall. The unit flew exclusively with the various versions of the Messerschmitt Bf 109 throughout the war.
Document 6: Ernst Heinkel: Dr. Ernst Heinkel (January 24, 1888 – January 30, 1958) was a German aircraft designer, manufacturer, Wehrwirtschaftsführer in the Third Reich, and member of the Nazi party. His company Heinkel Flugzeugwerke produced the Heinkel He 178, the world's first turbojet aircraft and jet plane, and the Heinkel He 176, the first rocket aircraft. He was awarded the German National Prize for Art and Science in 1938.
Document 7: Heinkel He 111: The Heinkel He 111 was a German aircraft designed by Siegfried and Walter Günter at Heinkel Flugzeugwerke in 1934. Through development it was described as a "wolf in sheep's clothing" because the project masqueraded the machine as civilian transport, though from conception the Heinkel was intended to provide the nascent Luftwaffe with a fast medium bomber.
Document 8: Luftwaffe: The Luftwaffe (] ) was the aerial warfare branch of the combined German Wehrmacht military forces during World War II. Germany's military air arms during World War I, the "Luftstreitkräfte" of the Army and the "Marine-Fliegerabteilung" of the Navy, had been disbanded in May 1920 as a result of the terms of the Treaty of Versailles which stated that Germany was forbidden to have any air force.
Document 9: 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 10: Heinkel He 64: The Heinkel He 64 was a sports plane built in Germany in 1933 to participate in the touring plane championships that year, designed by Siegfried and Walter Günter.
Document 11: Lehrgeschwader 1: "Lehrgeschwader" 1 (LG 1) (Demonstration Wing 1) formerly "Lehrgeschwader Greifswald" was a Luftwaffe multi-purpose unit during World War II, operating fighter, bomber and dive-bomber "Gruppen". The unit was formed in July 1936 and operated the Messerschmitt Bf 109, Messerschmitt Bf 110, Dornier Do 17, Heinkel He 111, Junkers Ju 88 and Junkers Ju 87.
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: Heinkel He 162: The Heinkel He 162 "Volksjäger (German, "People's Fighter"), the name of a project of the Emergency Fighter Program design competition, was a German single-engine, jet-powered fighter aircraft fielded by the Luftwaffe in World War II. Designed and built quickly, and made primarily of wood as metals were in very short supply and prioritised for other aircraft, the He 162 was nevertheless the fastest of the first generation of Axis and Allied jets. "Volksjäger" was the Reich Air Ministry's official name for the government design program competition won by the He 162 design. Other names given to the plane include "Salamander", which was the codename of its construction program, and Spatz" ("Sparrow"), which was the name given to the plane by Heinkel.
Document 14: Heinkel: Heinkel Flugzeugwerke (] ) was a German aircraft manufacturing company founded by and named after Ernst Heinkel. It is noted for producing bomber aircraft for the Luftwaffe in World War II and for important contributions to high-speed flight, with the pioneering examples of a successful liquid-fueled rocket and a turbojet-powered aircraft in aviation history, with both Heinkel designs' first flights occurring shortly before the outbreak of World War II in Europe.
Document 15: Heinkel He 112 operational service: Heinkel's He 112 was a fighter aircraft designed by Walter and Siegfried Günter. It was one of four planes designed to compete for the Luftwaffe's 1933 fighter contract, which was eventually won by the Messerschmitt Bf 109. Small numbers of the He 112 were used for a short time by the Luftwaffe, and small runs were completed for several other countries, but less than one hundred were completed in total.
