Aerosledge
Propeller-driven sledges used for transport and combat in deep snow.
An Aerosledge, known in Russian as an *aerosani*, is a propeller-driven vehicle that moves on skis or runners, functioning as a sledge, sleigh, or toboggan. These machines were employed for communication, mail delivery, medical aid, emergency recovery, and border patrol in places like northern Russia, as well as for recreational purposes. Constructed from lightweight plywood and mounted on skis, they were typically powered by repurposed vintage aircraft engines and propellers. The Soviet Red Army deployed aerosani during the Winter War and World War II.

Lore & Background
The first aerosledges may have been built in 1903–05 by Sergei Nezhdanovsky. In 1909–10, young Igor Sikorsky designed and tested an aerosledge, before going on to build multi-engine airplanes and helicopters. The ANT-I through ANT-V were a successful series of aerosani of the 1920s and ’30s, designed by aircraft engineer Andrei Tupolev. A claim exists that in 1924 the Soviets obtained plans and specifications for 'air sleighs' from Chester B. Wing, an aviator, automobile dealer and former mayor of St. Ignace, Michigan, U.S.A. The claim though has to be viewed in the context of a pre-World War I picture of an Igor Sikorsky machine in Kiev.
Reader's Guide
Military use of the aerosani goes back to at least the 1910s. During World War I, aerosani were used for reconnaissance, communicating, and light raiding in northern areas. During the 1939–40 Winter War against Finland some were equipped with a machine gun ring mount on the roof. They could carry four or five men and tow four more on skis. During World War II aerosani were used for reconnaissance, communication, and light raiding in northern areas thanks to their high mobility (25–35 km/h) in deep snow. Responsibility for aerosani was transferred to the Soviet Armoured Forces (GABTU) and orders were submitted for design and fabrication of lightly armoured versions, protected by ten millimetres of steel plate on the front. They were organized into transport or combat battalions of 45 vehicles, in three companies, often employed in cooperation with ski infantry. Aerosani were not used for direct assault because of their vulnerability to explosives such as mortar rounds. 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. In 1941 the armoured NKL-26, designed by M. Andreyev, started production at Narkomles. The following year, Gorki Narkorechflota developed the smaller, unarmoured GAZ-98, or RF-8, powered by a GAZ-M1 truck engine and a durable metal propeller. There was also an ASD-400 heavy assault sled used in World War II.

Frequently Asked Questions
What exactly is an Aerosledge?
An Aerosledge (aerosani) is a motorized sledge that glides over snow on skis or runners while being propelled by a propeller. Think of it as a cross between a toboggan and a small aircraft, built to cross deep snow where wheels or tracks would simply sink.
Who is credited with inventing the Aerosledge?
The earliest known builds date to roughly 1903–1905 and are often attributed to Sergei Nezhdanovsky, though the exact origin remains somewhat murky. The concept gained real traction in the 1910s when the Soviet military began experimenting with them for operational use.
What powers an Aerosledge?
Most models were fitted with surplus or repurposed vintage aircraft engines driving a pusher or puller propeller. The airframe itself was kept light—typically plywood panels mounted on a ski or runner chassis—so that a modest engine could still haul a rider and cargo across packed snow.
How were Aerosledges used in combat?
The Red Army fielded them during the Winter War against Finland and again in World War II for reconnaissance, light raiding, and rapid troop movement across snow-covered terrain. Beyond front-line work, they served as mobile mail carriers, medical-evacuation units, and border-patrol vehicles across the vast northern regions of Russia.
Why is the Aerosledge considered an important Soviet invention?
It solved a genuinely hard logistics problem: moving people and supplies across hundreds of kilometres of deep, trackless snow where conventional vehicles simply could not go. By borrowing the propulsion system of an airplane and the running gear of a sled, Soviet engineers created a practical, low-cost solution that remained in service from the 1910s well into the postwar era.
