The Indian Navy is planning to buy Submarine Mine Laying Equipment (SMILE) to augment existing capabilities of its conventional fleet. It has issued a Request for Information (RFI) to vendors and manufacturers seeking details in this regard, a Navy officer said here, reported by an Indian News Agency. The Indian Navy at present has a fleet of 16 conventional submarines, but is in the process of adding a few more when the Scorpene submarines currently being built by Mazgaon Docks are ready for induction and a follow-on project of the type is ordered. The SMILE, according to the RFI, should be capable of laying 24 ground mines and withstand maximum underwater speeds of the submarine. The basic design of the SMILE should comprise components and sub-systems such as two independent magazines capable of housing at least 12 mines each.
