A specification was put out in 1933 for a dive bomber.4 Arado, Blohm und Voss, Heinkel, and Junkers submitted designs.4 Only Heinkel and Junkers submitted a prototype and these were tested in 1936.4 Hermann Phlmann had the winning design.4
The Junkers Ju 87 brought terror across Europe in the early years of World War II.3 It had a siren that wailed during its dive.3
A device allowed the Ju 87 to pull out of a dive even when a pilot blacked out.1
During the winters on the eastern front some had skis installed.1
To aid in mass production the fuselage was made in two halves and joined at the centerline by a metal frame.1
To allow for a short undercarriage and allow for a large bomb, the wings were of a cranked wing design.1
The gunner-observer had a mount that he could rotate a 7.9 mm MG 17 on.4
The main bomb was located under the middle of the fuselage and when released a mechanism would hurl the bomb past the propeller disk.4
The Ju 87 prototype had a Rolls-Royce Kestrel engine (525 HP4 / 640 HP) and first flew in the spring of 1935.1,2,3,4 It had a two blade wooden propeller.4
Early prototypes had twin fins but this was replaced by a single fin.1,3
The next two prototypes had Junkers Jumo 210 engines (610 HP).3,4 These had single tail fins.3,4 The engine drove a three bladed variable pitch propellar.4
Over 5,700 were produced until September 1944.1,3
Starting in 1939 all production of the Ju 87 Stuka was at Weser at Tempelhof.1
The Junkers Ju 87A first flew in November 1936.3 The Junkers Ju 87B first flew in August 1938.3
The Ju 87 was used by Bulgaria, Germany, Hungary, Italy, Romania, and Slovakia.1
Bulgaria, Croatia, Germany, Hungary, Italy, and Romania.3
The Ju 87 Stuka was used on all fronts during the war.1 It was very vulnerable and relied on total air superiority to be used effectively.3
Typically a pilot would start their dive at 6,000' / 2,000 m and go down to 900' / 300 m before releasing their bombs.1 The dive angle was between 60° and 90°.1
Flying a Ju 87G, Hans-Ulrich Rudel destroyed over 500 / 5192 Soviet tanks.1 He also sunk a battleship, a cruiser, and a destroyer with his Stuka.2
The very first bombs dropped on September 1, 1939, were by three Junkers Ju 87 B-1s.4
There were five Stukageschwader equipped with Ju 87s that were used in the invasion of Poland in 1939.2
