The Russian Navy will receive at least 10 new Borey class strategic nuclear submarines in line with a revised state armament procurement program until 2020, Kommersant daily said in Tuesday.

The submarine fleet is expected to become the core of Russia's naval force in the future.

The revised document also envisions the procurement of 10 Graney class nuclear attack submarines and 20 diesel-electric subs, including six Varshavyanka class vessels.

Russian Prime Minister Vladimir Putin said last year that the procurement of new warships and submarines for the Navy would be a priority over the next decade. The Russian government has allocated five trillion rubles ($166 bln) or a quarter of the entire armament procurement budget until 2020 for this purpose.

In addition to submarines, the Navy will receive 14 frigates, 35 corvettes, six Buyan class small artillery ships and six Ivan Gren Class large landing ships.

Deputy Prime Minister Dmitry Rogozin said on Monday Russia will develop a detailed 30-year plan of strengthening its naval forces by June 2012.
