Kirowwerk
In 1941, the great Patriotic war began in the USSR; many heavy machinery factories were evacuated to the deep rear. At that time, Petropavlovsk was also a deep rear. Such factories operating in Petropavlovsk as the V. I. Lenin Plant, the S. M. Kirov Plant, and the V. V. Kuibyshev Plant were built in Petropavlovsk to build heavy equipment, i.e. tanks, armored personnel carriers, and so on. At the moment, factories produce and assemble small equipment.
