Development and Production History
From late 1920s the RKKA sought to upgrade its World War I-era artillery pieces. One of the modernized weapons was the 152-mm howitzer model 1909, initially designed by the French arms manufacturer Schneider. After a number of experiments it was determined that the muzzle velocity of the piece could be increased to about 395 m/s (further increase could result in a damage to the carriage). In 1930 at the Bolshevik Plant, the gun was experimentally fitted with a muzzle brake.
In 1930-1931, the Perm plant developed a modernization project. Initially, the only element of the project was lengthening the chamber to 340 mm (upgraded barrels received a mark "lengthened chamber"). In late production pieces minor changes in breechblock, cradle and elevation mechanism were introduced. Some pieces also had their wooden wheels replaced by steel ones with rubber tires. The modernized weapon was officially adopted as 152-mm howitzer model 1909/30.
The M1909/30 was a typical short-barrel howitzer, intended mostly for shooting with elevations from +20° to +41°, using separately loaded ammunition. The gun had interrupted screw breechblock; hydraulic recoil buffer and hydropneumatic recuperator were both mounted under the barrel. The carriage was of single trail type with limited traverse and, typically, unsprung wooden wheels (some pieces produced from 1937 had metal wheels with solid rubber tires). With the gun was issued limber, which had either wooden or metal wheels.
From 1931 to 1941 the Perm plant delivered 2,188 pieces.

Famous quotes containing the words development, production and/or history:
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
“The growing of food and the growing of children are both vital to the family’s survival.... Who would dare make the judgment that holding your youngest baby on your lap is less important than weeding a few more yards in the maize field? Yet this is the judgment our society makes constantly. Production of autos, canned soup, advertising copy is important. Housework—cleaning, feeding, and caring—is unimportant.”
—Debbie Taylor (20th century)
“Every member of the family of the future will be a producer of some kind and in some degree. The only one who will have the right of exemption will be the mother ...”
