Enhancing India's naval prowess and boosting tri-services synergy are set to be the focus of the Indian Navy's biannual commanders' conference onboard the country's first indigenous aircraft carrier INS Vikrant in the Arabian Sea on Monday. Defence Minister Rajnath Singh will address the top naval commanders at the 40,000-tonne ship that was commissioned into the Navy by Prime Minister Narendra Modi in September last. Built at a cost of around Rs 23,000 crore, INS Vikrant has a sophisticated air defence network and anti-ship missile system and has the capacity to hold 30 fighter jets and helicopters.
