During the past times, India was one of the seagoing countries. Seamen used to sail far and wide, transporting Indian commerce and culture. India was a primary ship-building country during the time of Napoleonic wars. It was only during the British dominion that it lost its reputation. India since Independence, has been trying to retrieve their doomed position. It has to defend its extensive coastline and islands in the Arabian Sea and Bay of Bengal. It has to defend and expand coastal land deep-seal fisheries. India`s territorial waters continue up to twelve nautical miles. It has some of its productive oil fields in the unfathomable sea, away from the shoreline. Bombay High oil field is 115 km west of the coast. The country`s economic zone stretches over 200 km into the sea, down the shoreline. It is almost 2 million sq. km. in area and demands fortification.
