Indian Navy Day was celebrated on December 4, 2025, honouring the decisive naval victory during Operation Trident in the 1971 India-Pakistan War. On the night of December 4-5, 1971, the Indian Navy launched a surprise missile attack on the Pakistani naval headquarters in Karachi, sinking several vessels. This was one of the earliest successful anti-ship missile attacks in naval warfare.

The Indian Navy's theme for 2025 is 'Combat Ready, Cohesive and Self-Reliant.' Admiral Dinesh Kumar Tripathi is the current Chief of Naval Staff. India operates two aircraft carriers — INS Vikramaditya and INS Vikrant (commissioned 2022). The Navy plays a crucial role in India's Indo-Pacific strategy and participates in multilateral exercises like Malabar, Samudra Shakti, and TROPEX.
