The feared Ju 87 Stuka aircraft, The WWII aircraft part of the Nazi arsenal. This documentary is about things you might not know about this German aircraft.

The Junkers Ju 87 or Stuka (from Sturzkampfflugzeug, "dive bomber") is 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 of 1936–1939 and served the Axis in World War II from beginning to end (1939–1945).

The aircraft is easily recognizable by its inverted gull wings and fixed spatted undercarriage. Upon the leading edges of its faired main gear legs were mounted ram-air sirens known as Jericho trumpets, which became a propaganda symbol of German air power and of the so-called Blitzkrieg victories of 1939–1942, as well as providing Stuka pilots with audible feedback as to speed. The Stuka's design included several innovations, including automatic pull-up dive brakes under both wings to ensure that the aircraft recovered from its attack dive even if the pilot blacked out from the high g-forces.

The Ju 87 operated with considerable success in close air support and anti-shipping roles during the outbreak of World War II. It led to air assaults in the invasion of Poland in September 1939. Stukas proved critical to the rapid conquest of Norway, the Netherlands, Belgium, and France in 1940. Though sturdy, accurate, and very effective against ground targets, the Stuka was, like many other dive bombers of the period, vulnerable to fighter aircraft. During the Battle of Britain of 1940-1941, its lack of maneuverability, speed, and defensive armament required a heavy fighter escort to operate effectively.

After the Battle of Britain, the Luftwaffe deployed Stuka units in the Balkans Campaign, the African and the Mediterranean theatres, and in the early stages of the Eastern Front war, where it was used for general ground support, as an effective specialized anti-tank aircraft, and in an anti-shipping role. Once the Luftwaffe lost air superiority, the Stuka became an easy target for enemy fighters, but it continued being produced until 1944 for lack of a better replacement. By 1945 ground-attack versions of the Focke-Wulf Fw 190 had largely replaced the Ju 87, but it remained in service until the end of the war in 1945.

The Ju 87's principal designer, Hermann Pohlmann, held the opinion that any dive-bomber design needed to be simple and robust. This led to many technical innovations, such as the retractable undercarriage being discarded in favor of one of the Stuka's distinctive features, it's fixed and "spatted" undercarriage. Pohlmann continued to carry on developing and adding to his ideas and those of Dipl Ing Karl Plauth (Plauth was killed in a flying accident in November 1927) and produced the Ju A 48, which underwent testing on 29 September 1928. The military version of the Ju A 48 was designated the Ju K 47.
