Russia's fourth Borei class (Project 955A) ballistic missile submarine will be officially laid down at a ceremony on July 30, Russian Navy Commander Vice-Admiral Viktor Chirkov said on Thursday.
The Borei class is set to become the mainstay of the Russian Navy's strategic nuclear deterrent fleet, replacing the ageing Project 941 (NATO Typhoon class) and Project 667 class (Delta-3 and Delta-4) boats.
"The official ceremony for laying down the Borei-class boat, named Knyaz Vladimir, will be held on Monday July 30," Chirkov said.
Three other Borei class boats are at various stages of development at the Sevmash shipyard on the Kola peninsula. Yury Dolgoruky is currently undergoing sea trials, whilst Alexander Nevsky and Vladimir Monomakh are under construction.
The Borei class will be armed with the Bulava ballistic missile, which is also in the final stage of development and due to enter service on Yury Dolgoruky later this year.
