TROPEX 2019 had commenced 7 Jan 2019 and was planned to be terminated by 10 Mar 2019. However, the JEM sponsored terrorist attack on the CRPF convoy in Pulwama on 14 February 2019 led to the rapid redeployment of the Indian Navy for Operations in North Arabian sea. About 60 ships of the Indian Navy, 12 ships of the Indian Coast Guard and 60 aircraft were part of TROPEX 19. TROPEX 19 had commenced with tri-services Amphibious Exercise in the A &amp; N islands with participation of Army and Air Force. This was followed by the largest Coastal Defence Exercise code named SEA VIGIL' on 22-23 January with participation of all 13 Coastal States and Union Territories along with all maritime stakeholders. The TROPEX itself was thus far the largest in terms of geographical spread covering the IOR and also with regard to the number of participating units.
