  • Indian Navy has given 76% Acceptance of Necessity (AON), and 66% cost-basis contracts to Indian vendors in 2014 and indigenisation of about 90% Naval ammunition has taken place. In addition, more than two-thirds of the Navy’s Modernisation Budget has been spent on indigenous procurement in the last five financial years. Of the 41 ships and submarines ordered by the Navy, 39 are from Indian shipyards. This is a testament to the Navy's commitment to achieving 'Aatmanirbhar Bharat
