The Russian Zvezdochka Shipbuilder has launched the K-407 Novomoskovsk, strategic submarine missile cruiser after an interim overhaul and modernisation programme.

Novomoskovsk is the last strategic nuclear submarine to undergo modernisation at the shipyard, and is to be delivered to the Russian Navy.

The vessel is the sixth missile submarine of Project 667BDRM (Delfin Class, Delta-4 by Nato classification), whose service life has been extended by ten years after the overhaul.

The Delfin Class submarines are armed with 16 intercontinental ballistic missiles and form the basis of the Russian sea-based strategic nuclear forces, according to ITAR-TASS News Agency.

The submarines that have undergone similar modernisation include K-51 Verkhoturye, K-84 Yekaterinburg, K-114 Tula, K-117 Bryansk and K-18 Karelia.
