India is a maritime nation strategically straddling the Indian Ocean with or substantive seaborne trade. The country�s economic well being is thus very closely linked to our ability to keep our sea-lanes free and open at all times. Besides, India has other maritime interests as well. Our island territories situated on our Western and Eastern seaboards are at considerable distances away from the mainland. To ensure their sustained development, umbilical linkages with the mainland and maritime security protection are essential pre-requisites of our maritime security. Our offshore assets within the Exclusive Economic Zone (EEZ) of 2.02 million sq. kms, fisheries and deep sea interests, major and minor harbours and the overall seaward security of long coastline and island territories are other vital aspects of our maritime dimension and Navy�s responsibilities. Indian Navy has consciously taken the difficult route of indigenisation in consonance with the national endeavour towards self-reliance. The Navy embarked upon a programme for indigenous construction of ships and development of major sub systems, sensors and weapon systems with the help of Defence Research and Development Organisation (DRDO) and Defence Public Sector Understandings (PSUs). Commissioning of the indigenously built destroyer, INS Delhi on November 15, 1997, & commissioning INS Mysore on June 2, 1999 have enabled the Navy to become a builder�s Navy and not just be a buyer�s Navy. Self-reliance through indigenisation has been the Navy�s guiding philosophy over the last half century.
