The first military aerosani used in Finland, the KM-5 and OSGA-6 (later called NKL-6), were initially built at the Narkomles Factory in Moscow. During World War II, improved NKL-16/41 and NKL-16/42 models were built, and production started at the ZiS and GAZ car factories, and at smaller industries such as the Stalingrad Bekietovskiy Wood Works.
