Project 677

As of 2004, the Russian Navy remains the only Project 677 operator with a single ship on order. The Saint-Petersburg submarine, an Amur 1650-class boat, was laid down in December 1997 at Admiralty Shipyards, and despite lack of funds, was expected to enter service with the Russian Navy in the 2005-2006 timeframe. Nevertheless, the Russian Navy priority are nuclear-powered submarines with Amur/Lada-class intended for the export market and secondary missions within the Russian Navy. The Amur 1650/Lada submarine has been designed to operate in the littoral environment, in deep water and shallow water areas, and in any climate worldwide. It features six 533mm torpedo tubes with 18 weapons between torpedoes, mines, missiles and rockets at the bow compartment. According to Russian reports, it is one of the most quiet and lethal submarines ever built. It can be outfitted with custom equipment depending on customer requirements. These ships may be fitted with vertical launch missile silos. In June 2005 Saint-Petersburg was preparing for factory sea trials. On 28 July 2005, Rubin announced that a second Lada project submarine for the Russian Navy was laid down at FSUE Admiral Shipyards. The new submarine was named Kronshtadt and was the first production series submarine. This boat should be commissioned by 2009 or 2010. The Saint Petersburg was accepted by the Russian Navy in October 2006 to conduct sea trials. It will be officially commissioned in 2010 fitted with an advanced anti-sonar hull coating, an extended cruising range, and advanced anti-ship and anti-submarine weaponry, including Club-S cruise missile systems. These features were not available in October 2006. The Russian Navy plans call for the commissioned of eight boats replacing Kilo-class submarines in the Baltic and Black Sea fleets. In Febraury 2014, the Russian Navy announced that the Lada class attack submarines would be equippped with an air-independent ultra-quiet propulsion system beginning in 2016. In January 2016 the Russian Navy scaled down the Lada class project to 3-4 boats in favor of the Kalina class submarines.
