Indian Navy Day 2025 is observed every year on December 4 to honour the unwavering courage, discipline and operational excellence of the Indian Navy. The day highlights the Navy’s critical role in safeguarding India’s maritime borders, protecting sea trade routes and responding swiftly to national and international crises. It also reflects India’s growing focus on indigenous defence capability and its expanding maritime influence across the Indian Ocean region.

History: Operation Trident 1971

The origin of Indian Navy Day lies in the successful execution of Operation Trident, a landmark naval offensive during the 1971 India-Pakistan War.
On the night of December 4, 1971:

• Indian Navy missile boats launched a decisive strike on Pakistan’s Karachi Harbour.

• Key fuel depots, naval vessels and strategic installations were destroyed.

• Aircraft from INS Vikrant targeted enemy airfields in Chittagong and Khulna, further weakening Pakistan’s operational capability.

These coordinated attacks marked India’s first major naval offensive and significantly influenced the outcome of the 1971 war. The success of Operation Trident established December 4 as a day of remembrance and a symbol of naval excellence.
