This news is dated, but wasn’t picked up widely (if at all).
Russia will start construction on eight nuclear-powered submarines in 2014-2015, according to the chief of Sevmash.
In 2015, Russia will lay the first sections of two Borey-class nuclear-powered ballistic missile submarines (SSBNs) and three Yasen-class attack submarines (SSNs), Sevmash General Director Mikhail Budnichenko told ITAR-TASS on 7 February.
Speaking at Defexpo 2014 in New Delhi, Budnichenko indicated that Sevmash will begin construction on two Borey SSBNs and one Yasen SSN in 2014.
The Borey SSBNs will be modernized Proyekt 955A submarines, reportedly stealthier than the first three Proyekt 955 boats. The Yasen SSNs will be improved Proyekt 885M submarines.
If Russia keeps to the schedule outlined by the Sevmash chief, it will put all remaining units of eight planned Borey SSBNs as well as seven Yasen SSNs into build.
The total number of Yasen-class submarines has been reported at six or seven at various times. They would include Severodvinsk (Proyekt 885) and either five or six Proyekt 885M boats.
