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:
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“I have an intense personal interest in making the use of American capital in the development of China an instrument for the promotion of the welfare of China, and an increase in her material prosperity without entanglements or creating embarrassment affecting the growth of her independent political power, and the preservation of her territorial integrity.”
—William Howard Taft (1857–1930)
“As long as fathers rule but do not nurture, as long as mothers nurture but do not rule, the conditions favoring the development of father-daughter incest will prevail.”
