Indiainfo-icon is going to buy 131 surface-to-air missiles from Israelinfo-icon in a $70 million deal, Indian defence ministry announced on Tuesday ahead of a visit by Israeli Prime Minister Benjamin Netanyahu.

The Barak missiles made by Rafael Advanced Defense Systems will be used for India's first aircraft carrier which is under construction.

Netanyahu will lead a businessinfo-icon delegation to India on a four-day trip expected in mid-January. Israel has become a major defence supplier to India, selling an average of $1 billion of military equipment each year.

Last April, the two countries signed a military deal worth nearly $2bn which includes the supply over several years of medium-range surface-to-air missiles, launchers and communications technologyinfo-icon. It was unclear whether the deal announced Tuesday was part of that.

The Indian defence ministry also said it had approved the purchase of 240 bombs from Russiainfo-icon's JSC Rosonboron Exports for $188mn.

"This procurement will address the deficiency of precision-guided munitions in the IAF (Indian Air Force) arsenal, besides enhancing the offensive capabilities of the IAF," it said in a statement.

India, which has longstanding territorial disputes with neighbours Chinainfo-icon and Pakistaninfo-icon, has signed several big-ticket defence deals since PM Narendra Modi came to power in 2014. It has, however, been moving away from relying on traditional ally Russia for military hardware.
