Indian and Russian navies will conduct their biggest-ever 15-day war games in the Arabian Sea from Wednesday.

During this period, India will get a feel of the Krivak class missile frigate, which it will acquire in June.

The war manoeuvres, the first between the two navies, will get underway when the Russian flotilla, comprising missile cruisers, Krivak class frigates, Kashin class destroyers and specialised anti-submarine vessels, berths at Mumbai on Tuesday.

The Russian flotilla will carry out surface-to-surface, anti- submarine and air defence manoeuvres with Indian warships of 'matching composition'.

After the exercises in the Arabian Sea, the location of which has not been disclosed, the Russian flotilla will conduct similar exercises with India's eastern naval fleet in the Bay of Bengal off Vizag.

The exercises in the Arabian Sea, which will include naval fighters, aircraft carrier INS Viraat, Jaguar maritime fighters, Seaking and Kamov 28 anti-submarine helicopters, will be carried out anywhere between 50 to 120 nautical miles off the Indian coastline, naval officials said.
