The blue waters of the Bay of Bengal glitter invitingly to our left all through the sweltering drive from Chennai’s famous Marina Beach to Kovalam, 45 km south of the city. There is no missing that this is the road to Defexpo 2018 — every 200 metres, Prime Minister (PM) Narendra Modi’s image beams out of hoardings, welcoming visitors to India’s premier land and naval systems exhibition.
This will be the 10th edition of Defexpo, first held in 1999. It continued as a biennial event in New Delhi until 2016, when Manohar Parrikar hosted it in his home state, Goa.
