Commissioning of three indigenous naval ships
One line
The Prime Minister commissioned INS Dunagiri, INS Sanshodhak, and INS Agray, adding indigenous combat and survey capabilities to the Navy.
Summary
The three vessels illustrate how fleet strength depends on different roles, including surface combat, hydrographic survey, and shallow-water anti-submarine work. Indigenous shipbuilding also tests design and supply-chain depth.
