   In 2009 India launched its first indigenously designed nuclear-powered ballistic missile submarine. The whole project was kept in high secrecy. Some sources report, that in 2014 submarine has been secretly moved out of harbor for sea trials. Sea trials represent the final stage before submarine becomes operational with the Indian Navy. It is considered a milestone in the development of the Indian Navy. India joined five other countries, capable of designing and building nuclear-powered submarines. Other countries of this club are China, France, Russia, United Kingdom and the USA.

   The lead boat was named INS Arihant (the one, who has conquered all internal enemies). Design of this boat is based on the Charlie I submarine, leased from the former Soviet Union to India from 1987 to 1991. For a long time this submarine was referred as the ATV or Advanced Technology Vessel, to maintain secrecy. It was a part of a science project, lasting nearly 11 years. The submarine and power plant were developed with Russian assistance. The Arihant is expected to be commissioned for full service with the Indian Navy in the near future. Possibly 2015 or 2016. Three more bots of the same class are under construction and two more are planned.

   It is reported that Arihant carries four K-4 ballistic missiles. These have a range of 3 000-3 500 km and carry nuclear warheads. It is a submarine-launcher version of the Agni III ballistic missile. Submarine-launched ballistic missiles will give India a second strike capability. The submarine can remain hidden deep in the Indian Ocean or launch missiles within territorial waters. Some sources report that submarine can also carry twelve shorter-range K-15 ballistic missiles. These non-strategic missiles have a range of 750-1 900 km. Also there are six 533-mm torpedo tubes for missiles and torpedoes.

   The Arihant class SSBN is powered by an 83 MW nuclear pressurized water reactor, developed at the Center of Atomic Research. This reactor uses highly enriched uranium as a fuel and light water as coolant. It generates high levels of heat, that drives a steam turbine, which in turn rotates a propeller. Nuclear-powered submarines go faster and spend longer time at sea than conventional diesel counterparts. Sea endurance of the INS Arihant is limited only by food supplies.
