Lt Tamara Fyodorovna Konstantinova was a pilot of a ground-attack aircraft of which how many units were produced during the war?
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.
Boris Shpitalniy Boris Shpitalniy graduated from MAMI Moscow State Technical University in 1927. Three years later, Boris Shpitalniy together with Irinarkh Komaritsky designed the ShKAS machine gun, a 7.62 mm machine gun widely used by Soviet aircraft in the 1930s and during World War II. In 1939, a small number of Ultra-ShKAS were produced featuring a firing rate of 3,000 rounds per minute, but these saw only limited use due to reliability problems. ShKAS served as the basis for the ShVAK cannon in 1936 (designed in collaboration with Semyon Vladimirov). This 20-mm autocannon was installed in many Soviet aircraft including Yakovlev Yak-1, Polikarpov I-153 and I-16, Lavochkin La-5 and La-7, LaGG-3, early Ilyushin Il-2, and Soviet-modified Hawker Hurricane aircraft, as well as T-38 and T-60 tanks. His 37 mm autocannon, the Sh-37, was less successful though, and saw only brief service between 1941 and 1942.
