The Russian shipyard Sevmash has started construction of the fourth Borey-class nuclear powered submarine Svyatitel Nikolay, a source in Severodvinsk tells RIA Novosti.
The keel of the fourth Borey-class strategic sub – to be named Syvatitel Nikolay or St. Nicholas in English - was supposed to be laid on December 22nd, but was postponed to the first quarter of 2010 because of the repeated problems with the test-launching of the Bulava missile.
