The GAZ-AA is a truck produced at the Gorki Auto Plant in the Soviet Union from 1932 to 1938, and was the factory's first truck produced under the GAZ brand. Russian-speakers often refer to it as a polutorka (полуторка) - meaning "one-and-a halfer", with reference to its carrying capacity of 1.5 tonnes (1500 kilograms).

On 31 May 1929 the Supreme Soviet of the National Economy of the Soviet Union (Russian: Высший совет народного хозяйства СССР) made an agreement with the Ford Motor Company to produce Ford Model A and Model AA vehicles, and the Soviet Metallostroy organisation^[1] (Russian: Металлострой) started constructing an American-designed automotive plant in Nijni Novgorod.

Initially, 10 Ford Model AA trucks were built at the plant,^[2][3] under the name NAZ (for Nijni Novgorod Avtomobilni Zavod). Soviet engineers prepared their own mechanical blueprints for production, specifying a truck to be made with thicker steel and to have an upgraded suspension system. In 1932 the city of Nizhni Novgorod adopted its new name, Gorki - after Maxim Gorki (1868-1936) - and in 1933 the plant was renamed to Gorki Automobilni Zavod, and the trucks began to use the model designation GAZ-AA. By 1932 mass-production had started, with around 60 trucks were built at the plant daily from knock-down kits sent by Ford.^[4]

Soon assembly started of GAZ-A passenger vehicles,^[5] which were based on the Ford Model A and were also built from knock-down kits imported into the Soviet Union. By that time GAZ-AA trucks comprised the majority of trucks used by the Red Army.^[4] Several modifications of the GAZ-AA trucks started getting produced, including dump trucks (410),^[6] semi-trucks (MS), fire trucks (PMG-1)^[7] and tractors (905).^[8]

By 1938, nearly 1 million of these trucks had been produced and sold. By that time a modernized variant of the GAZ-AA trucks, under the GAZ-MM index entered production, with the engine from the GAZ-M1, that boosted the vehicle's power to 50 hp, with the compression ratio increased to 4.6, giving a maximum speed of 80 km / h.^[9][10]
