The Indian Navy has successfully concluded its month-long annual war drill, theatre level readiness and operational exercise (TROPEX), which was held in the Arabian Sea and Northern Indian Ocean.
Around 50 ships and submarines, along with more than 70 aircraft from the three naval commands participated in the exercise.
TROPEX-2015 was intended to prove the Indian Navy's Concept of Operations and restate its readiness and capability to fulfil a range of roles in support of national objectives.
The navy's two Carrier Task Forces, Viraat and Vikramaditya, were deployed simultaneously at sea, along with defence satellite Rukmini.
The INS Chakra nuclear submarine, P8I long-range maritime reconnaissance aircraft, INS Kolkata guided missile destroyer and INS Kamorta anti submarine warfare corvette, also participated in several war-fighting concepts.
During TROPEX-15, the navy's offensive capabilities were strengthened across all dimensions, including network-centric operations, and its Op Logistics capability to sustain fleet operations for extended periods at large distances.
The exercise also saw participation of units from the Indian Air Force and the Indian Coast Guard.
In February, the navy completed a large-scale humanitarian assistance and disaster relief (HADR) exercise in the Lakshadweep Islands.
The exercise involved a simulation of a major cyclone hitting the Lakshdweep Islands and disrupting vital services and causing extensive property destruction, loss of life and dislocation.
