Development
In 1940, A.A. Volkov and S.A.Yartsev created an autocannon called TKB-201 for the new 23 mm round. It was intended to be the primary weapon of the Ilyushin Il-2 ground attack aircraft. The original intention was to create a gun capable of penetrating German tank armour.
Due to unavailability of Il-2, the first airborne testing was performed using a German Messerschmitt Bf 110 heavy fighter. After testing on Il-2 in 1941, TKB-201 was accepted into service as VYa-23. A total of 64,655 VYa-23 were built.

Famous quotes containing the word development:
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
“Understanding child development takes the emphasis away from the child’s character—looking at the child as good or bad. The emphasis is put on behavior as communication. Discipline is thus seen as problem-solving. The child is helped to learn a more acceptable manner of communication.”
—Ellen Galinsky (20th century)
“Good schools are schools for the development of the whole child. They seek to help children develop to their maximum their social powers and their intellectual powers, their emotional capacities, their physical powers.”
—James L. Hymes, Jr. (20th century)
