How the exam will ask it
ప్రిలిమ్స్
- INS Mangrol is an indigenously built vessel of the Indian Navy equipped with sonar and torpedoes for coastal defence.
- Sonar uses sound propagation to detect and locate objects underwater, which is why it is central to anti-submarine warfare.
- Commissioning is the formal induction of a ship into naval service, after which it is prefixed INS.
మెయిన్స్
GS-III (Defence, Security): India's long coastline and shallow-water approaches demand dedicated anti-submarine and coastal defence assets. Indigenous construction of vessels like INS Mangrol advances defence indigenisation under Atmanirbhar Bharat, cutting import dependence and building the domestic shipbuilding base. The way forward is timely delivery, indigenous sensors and weapons, and sustained maritime surveillance.
