MOSCOW, September 16 (RIA Novosti) - Russia's Zvezdochka shipyard said on Wednesday it will install Club-S cruise missile systems on four Kilo class diesel submarines in service with the Indian navy in the next five years.
Russia has built ten Kilo class submarines for India. Only two of them — the INS Sindhugosh and INS Sindhuvijay — have reportedly been equipped with the Club-S (SS-N-27) cruise missiles to date.
"The new missile system will be installed on the INS Sindhuratna, INS Sindhuraj, INS Sindhushastra, and INS Sindhuvir. The retrofit will be carried out at Indian shipyards," the shipyard in northern Russia said in a statement.
"Zvezdochka will finish this work in the next five years," the statement said.
The Club-S subsonic cruise missile is designed for launch from a 533 mm torpedo tube, or a vertical launch tube. It has a range of 160 nautical miles (about 300 km). It uses an ARGS-54 active radar seeker and Glonass satellite and inertial guidance.
In addition, Zvezdochka is getting ready to overhaul another Indian Kilo class submarine — the INS Sindhurakshak under a deal which is expected to be signed in spring 2010.
"The submarine will be delivered to Severodvinsk in June 2010," the shipyard said.
Russia agreed in 2001 to upgrade all 10 Indian Kilo class submarines and has previously overhauled four subs at the Zvezdochka shipyard.
The upgrade program involves a complete overhaul of the submarines, including their hull structures, as well as improved control systems, sonar, electronic warfare systems, and an integrated weapon control system. The upgrades are reported to be costing about $80 million.
Russia's Kilo-class diesel-electric submarines have gained a reputation as extremely quiet boats, and have been purchased by China, India, Iran, Poland, Romania and Algeria.
