Question: For what war did the "Stuka" plane beat the Heinkel He 118?

full_context: Document 1: Kōkūtai: A Kōkūtai (航空隊 ) was, during World War II and in the Imperial Japanese Navy, a type of aerial combat unit, similar to the Air Groups in service in the other armies and navies of the time (called "Group" in the British Royal Air Force, "Gruppe" in the German Luftwaffe, "Groupe" in the French Armée de l'Air etc.). Although belonging to the Imperial Navy the Japanese Kōkūtai could be based at land or on board naval aircraft carriers and were constituted by hundreds of men and aircraft (that latters were distributed in smaller units called Hikōtai, the equivalent of squadrons). For example, the famous 343 Kōkūtai (a fighter group, divided in three Hikōtai) was based at land while the 652nd Kōkūtai (a bomber group) was carrier-based. As in general in the Imperial Japanese Navy Air Service, most pilots and aircrew members of a Kōkūtai were non-commissioned officers.
Document 2: 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 3: Defence of the Reich: The Defence of the Reich (German: "Reichsverteidigung" ) is the name given to the strategic defensive aerial campaign fought by the "Luftwaffe" over German-occupied Europe and Nazi Germany during World War II. Its aim was to prevent the destruction of German civilians, military and civil industries by the Western Allies. The day and night air battles over Germany during the war involved thousands of aircraft, units and aerial engagements to counter the Allied strategic bombing campaign. The campaign was one of the longest in the history of aerial warfare and with the Battle of the Atlantic and the Allied Blockade of Germany was the longest of the war. The "Luftwaffe" fighter force defended the airspace of German-occupied territory against attack, first by RAF Bomber Command and then against the United States Army Air Forces (USAAF).
Document 4: Arado Ar 81: The Arado Ar 81 was a German prototype dive bomber. Because the Reich Air Ministry decided to purchase the competing Junkers Ju 87, only three prototypes of the Ar 81 were completed.
Document 5: List of military aircraft of Denmark: The following list contains the aircraft used by the Royal Danish Air Force or its predecessors, the Danish Army Air Corps and Royal Danish Naval Aviation. During the Nazi occupation from 1940 to 1945, Danish military aviation was prohibited. The aircraft currently in use are highlighted in blue.
Document 6: 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 7: United States Army Air Forces: The United States Army Air Forces (USAAF or AAF) was the military aviation service of the United States of America during and immediately after World War II, successor to the United States Army Air Corps and the direct predecessor of the United States Air Force. The AAF was a component of the United States Army, which in 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff.
Document 8: 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 9: German Air Force: The German Air Force (German: "Luftwaffe" (] ), the German-language generic term for "air force") is the aerial warfare branch of the Bundeswehr, the armed forces of Germany. With a strength of 28,448 personnel (28 February 2017), it is the fourth largest air force within the European Union, after the air forces of the United Kingdom, France and Italy. Although its budget has been significantly reduced since the end of the Cold War in 1989–1990, the Luftwaffe is still among the best-equipped air forces of the world.
Document 10: 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.
Document 11: 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 12: 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 13: 9th Air Division (Germany): 9. Flieger-Division (9th Air Division) was one of the primary divisions of the German Luftwaffe in World War II. The division was founded on 1 February 1940 in Jever and initially subordinated to the Oberkommando der Luftwaffe (OBdL). On 23 May 1940 the division was subordinated to the Luftflotte 2 and transferred to Soesterberg in July 1940. The unit was redesignated "IX. Fliegerkorps" in November 1940.
Document 14: 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 15: 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".
