Navy Day 2020 


The Navy plans to celebrate 2021 as ‘Swarnim Vijay Varsh’ as part of commemorating the 50th anniversary of the victory in the 1971 War. 

  • Every year, India celebrates December 4 as Navy Day to commemorate Operation Trident – a key offensive during the 1971 India-Pakistan War, when the Indian Navy inflicted heavy damage on Pakistani vessels in Karachi harbour
  • The same day also marks the end of Navy Week, which, too, is celebrated annually.
  • The Indian navy fearlessly protects our coasts and also renders humanitarian assistance in times of need. 


Operation Trident

  • The India-Pakistan War of 1971 had begun on December 3, when the Pakistan Air Force launched pre-emptive strikes on airfields in Western India. 
  • India responded by formally declaring war in the wee hours of December 4. 
  • On December 4, under Operation Trident, the Indian Navy sank three vessels near the Pakistani port city of Karachi. 
  • The stars of the mission were the then-recently acquired Soviet Osa missile boats, fitted with 4 SS-N-2 (P-15) Styx missiles.


India-Pakistan 1971 war: 13 days that shook the subcontinent

  • The Indian Air Force also played a crucial role during Operation Trident, when Karachi’s Kemari oil tanks were strafed by the IAF on the same day in an independent operation which it did not claim.
  • On December 5, the Indian Navy’s Western C-in-C, Vice Admiral SN Kohli received the code word “Angaar”, which meant success in Operation Trident.
  • The 1971 War ended on December 16, as India sealed its victory when the instrument of surrender was signed by Lt Gen A A K Niazi of Pakistan with Lt Gen J S Aurora watching, at Dhaka at 4.55 pm that day. That remains the abiding image of the 1971 War.
