Development History
In 1936 the Red Army adopted the 122 mm gun M1931, also known as A-19. Unlike earlier ordnance pieces used by the Red Army, it had split trail carriage with suspension, and consequently improved mobility and traverse. The carriage of M1931 had a number of shortcomings though. The elevation mechanism was slow and unreliable; solid-tired wheels hindered mobility to some extent; there were technological problems in carriage production.
Soon after the M1931, the Red Army received another artillery piece in form of the 152 mm howitzer-gun M1937 (ML-20), developed at the No. 172 Plant, under F. F. Petrov. This led to an upgrade of the M1931, handled also by Petrov's design bureau. The barrel of the M1931 was placed on the carriage of a ML-20. The improved gun successfully underwent trials in September–October 1938 and on 29 April 1939 was adopted as 122 mm corps gun M1931/37. Unusually, the new variant, like the old one, was referred to as A-19.

Famous quotes containing the words development and/or history:
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“Philosophy of science without history of science is empty; history of science without philosophy of science is blind.”
—Imre Lakatos (1922–1974)
