Mikhail Kalashnikov began his career as a weapon designer in 1941, while recuperating from a shoulder wound which he received during the Battle of Bryansk. Kalashnikov himself stated…”I was in the hospital, and a soldier in the bed beside me asked: ‘Why do our soldiers have only one rifle for two or three of our men, when the Germans have automatics?’ So I designed one. I was a soldier, and I created a machine gun for a soldier. It was called an Avtomat Kalashnikova, the automatic weapon of Kalashnikov—AK—and it carried the date of its first manufacture, 1947.”
The AK-47 is best described as a hybrid of previous rifle technology innovations. “Kalashnikov decided to design an automatic rifle combining the best features of the American M1 and the German StG44.” Kalashnikov’s team had access to these weapons and had no need to “reinvent the wheel”. Kalashnikov himself observed: “A lot of Russian Army soldiers ask me how one can become a constructor, and how new weaponry is designed. These are very difficult questions. Each designer seems to have his own paths, his own successes and failures. But one thing is clear: before attempting to create something new, it is vital to have a good appreciation of everything that already exists in this field. I myself have had many experiences confirming this to be so.”
Kalashnikov started work on a submachine gun design in 1942 and with a light machine gun in 1943. “Early in 1944, Kalashnikov was given some 7.62×39mm M43 cartridges and informed that there were several designers working on weapons for this new Soviet small-arms cartridge. It was suggested to him that this new weapon might well lead to greater things, and he undertook work on the new rifle.” In 1944, he entered a design competition with this new 7.62×39mm, semi-automatic, gas-operated, long stroke piston, carbine, strongly influenced by the American M1 Garand. “The rifle that Kalashnikov designed was in the same class as the familiar SKS-45 Simonov with fixed magazine and gas tube above the barrel.”However, this new Kalashnikov design lost out to a Simonov design.

In 1946, a new design competition was initiated to develop a new assault rifle. Kalashnikov submitted an entry. It was gas-operated rifle with a short-stroke gas piston above the barrel, a breech-block mechanism similar to his 1944 carbine, and a curved 30-round magazine. Kalashnikov’s rifles AK-1 (with a milled receiver) and AK-2 (with a stamped receiver) proved to be reliable weapons and were accepted to a second round of competition along with other designs.
These prototypes (also known as the AK-46) had a rotary bolt, a two-part receiver with separate trigger unit housing, dual controls (separate safety and fire selector switches) and a non-reciprocating charging handle located on the left side of the weapon. This design had many similarities to the STG 44. In late 1946, as the rifles were being tested, one of Kalashnikov’s assistants, Aleksandr Zaitsev, suggested a major redesign to improve reliability. At first, Kalashnikov was reluctant, given that their rifle had already fared better than its competitors. Eventually, however, Zaitsev managed to persuade Kalashnikov.
In November 1947, the new prototypes (AK-47s) were completed. It utilized a long-stroke gas piston above the barrel. The upper and lower receivers were combined into a single receiver. The selector and safety were combined into a single control-lever/dust-cover on the right side of the rifle. And, the bolt-handle was simply attached to the bolt-carrier. This simplified the design and production of the rifle. The first army trial series began in early 1948. The new rifle proved to be reliable under a wide range of conditions with convenient handling characteristics. In 1949, it was adopted by the Soviet Army as “7.62 mm Kalashnikov assault rifle (AK)”.
