The Defense Ministry said in a written statement Saturday the air force would receive 14 of the next-generations this year and another 16 in 2014.
Russia already has 29 Su-34s, known within NATO as the Fullback, in its air fleet.
The planes, which are built by Sukhoi at a plant in remote Siberia, will eventually replace the Su-24 Fencer currently in use by the air force and navy, Russia's RIA Novosti news agency said.
The Fullback can carry 8 tons of precision-guided weapons and has a range of more than 4,000 kilometers (2,485 miles).
