The story

Founded by Igor Afrikantov in 1947.1

The company was founded in 1945, by the decree of the Council of People's Commissars of the USSR dated December 27, 1945, a Special Design Bureau (OKB) was established on the basis of the Nizhny Novgorod Machine-building Plant to create equipment for the nuclear industry.

In 1960, the OKB was awarded the highest state award, the Order of Lenin, for its participation in the creation of the power plant of the first nuclear icebreaker: Lenin.

In 1985, the OKB was awarded the Order of the October Revolution for its significant contribution to the development of nuclear technology.

In 1998 the enterprise was named after its former chief designer and director I. I. Afrikantov.

In 2004, by a decree of the Government of the Russian Federation, OKBM was granted the status of a Federal Scientific and Production Center.

In 2008, the open joint-stock company “Experimental Design Bureau of Mechanical Engineering named after I. I. Afrikantov” was registered. The company was created as a result of the transformation of the federal state's unitary enterprise “Experimental Design Bureau of Mechanical Engineering named after I. I. Afrikantov” and became its legal successor.

In 2014, the company changed its name to a joint-stock company, as JSC Afrikantov OKBM.
