The AK-47 is a selective-fire, gas-operated 7.62×39mm assault rifle, first developed in the Soviet Union by Mikhail Kalashnikov. It is officially known in the Soviet documentation as Avtomat Kalashnikova (Russian: Автомат Калашникова). It is also known as Kalashnikov, AK, or in Russian slang, Kalash. No number was present in the Soviet military nomenclature for Kalashnikov's assault rifles until the adoption of the AK-74. Design work on the AK-47 began in the last year of World War II (1945). After the war in 1946, the AK-47 was presented for official military trials. In 1948 the fixed-stock version was introduced into active service with selected units of the Soviet Army. An early development of the design was the AKS (S—Skladnoy or "folding"), which was equipped with an underfolding metal shoulder stock. In 1949, the AK-47 was officially accepted by the Soviet Armed Forces[10] and used by the majority of the member states of the Warsaw Pact. Even after six decades the model and its variants remain the most popular and widely used assault rifles in the world because of their durability, low production costs, availability, and ease of use. The AK-47 has been manufactured in many countries and has seen service with armed forces as well as irregular forces worldwide, and was the basis for developing many other types of individual and crew-served firearms. More AK-type rifles have been produced than all other assault rifles combined.
