Lt. Gen. Mikhail Kalashnikov, the arms designer credited by the Soviet Union with creating the AK-47, the first in a series of rifles and machine guns that would indelibly associate his name with modern war and become the most abundant firearms ever made, died Monday in Izhevsk, the capital of the Russia’s Udmurtia republic, where he lived. He was 94.

Viktor Chulkov, a spokesman for the republic’s president, confirmed the death, the Itar-Tass news agency reported.

Born a peasant on the southern Siberian steppe, Gen. Kalashnikov had little formal education and claimed to be a self-taught tinkerer who combined innate mechanical skills with the study of weapons to conceive of a rifle that achieved battlefield ubiquity.

His role in the rifle’s creation, and the attention showered on him by the Kremlin’s propaganda machine, carried him from conscription in the Red Army to senior positions in the Soviet arms-manufacturing bureaucracy and ultimately to six terms on the Supreme Soviet.

Tens of millions of Kalashnikov rifles have been manufactured. Their short barrels, steep front-sight posts and curved magazines made them a marker of conflict that has endured for decades.

The weapons also became both Soviet and revolutionary symbols and widespread instruments of terrorism, child-soldiering and crime.

The general, who sometimes lamented the weapons’ unchecked distribution but took pride in having invented them and their reputation for reliability, weathered the collapse of the Soviet Union to assume a public role as a folk hero and unequivocal Russian patriot.

A Soviet nostalgist, he also served as the unofficial arms ambassador of the revived Russian state. He used public appearances to try to cast the AK-47’s checkered legacy in a positive way and to complain that knockoffs were being manufactured illegally by former Soviet allies and cutting into Russian sales.

The weapon, he said, was designed to protect his motherland, not to be used by terrorists or thugs.

“This is a weapon of defense,” he said. “It is not a weapon for offense.”

Mikhail Timofeyovich Kalashnikov was born in Kurya on Nov. 10, 1919. He was married twice, the second time to Ekaterina Kalashnikova, a technician in his design bureau.

He is survived by a son from his first marriage, Viktor Kalashnikov, who is also an arms designer; a daughter from his second marriage, Elena Krasnovskaya; a stepdaughter, Nelya; and several grandchildren.
