PPSh 42 Low-poly 3D model

The PPS was created in response to a Red Army requirement for a compact and lightweight weapon with similar accuracy and projectile energy to the Soviet PPSh-41 submachine gun widely deployed at the time, with reduced rate of fire, produced at lower material cost and requiring fewer man-hours, particularly skilled labour. Sudayev was ordered by the State Commission for Armaments to perfect for large-scale production the sub-machine gun design of Lieutenant I.K. Bezruchko-Vysotsky from the Dzerzhinsky Artillery Academy, who had created two prototypes in 1942; the second of these was the basis of Sudayev's gun. During design, emphasis was placed on simplifying production and eliminating most machining operations; most of the weapon's parts were sheet-steel stamped. These measures reduced the number of machined components to a bare minimum, cutting down machining time by more than half, to 2.7 hours of machining instead of 7.3 hours for the PPSh-41. There were also savings of over 50% in raw steel usage, down to 6.2 kg instead of 13.9 kg, and fewer workers were required to manufacture and assemble the parts. Thanks to the improvements in production efficiency, the Soviet planners estimated that the new gun would have allowed an increase in monthly submachine gun output from 135,000 units to 350,000 weapons.
