The Indian Navy is all set to add a brand new tanker INS Deepak to its fleet this month enhancing its capabilities as a blue-water navy. With a sister ship, INS Shakti, due to join in June-July, the additions will add a distinct punch. The ship will have a flight deck and have a double hull with a capacity to refuel four ships at a time. The two ships will join the two older fleet tankers, INS Jyoti and INS Aditya, currently being operated by Navy. The tankers are equipped with four AK-630 guns and have an endurance of 10,000 nautical miles at a speed of 16 knots. AIR correspondent reports that the Indian Navy's strategic area of interest stretches from the Hormuz Strait to Malacca Strait. It currently has over 40 warships on order at Indian shipyards, including six French designed Scorpene submarines, and a 40,000-tonne indigenous aircraft carrier being built at the Cochin Shipyard. It also has a refit programme of the 44,570-tonne Admiral Gorshkov renamed INS Vikramditya underway at a Russian shipyard as well as construction of three additional Talwar-class stealth frigates.
