His appointment must now be approved by Russian lawmakers.
The change comes weeks after Timur Ivanov, a Russian deputy defence minister in charge of military construction projects, was jailed pending an investigation and trial on charges of bribery.
In line with Russian law, the entire Russian cabinet resigned on Tuesday when Mr Putin began his fifth presidential term at a glittering Kremlin inauguration.
