* France's Jean-Yves Le Drian to visit India to sign deal
* Multibillion-dollar deal to be signed on Friday

India's cabinet cleared the purchase of 36 Rafale fighter jets from Dassault Aviation on Wednesday, paving the way for signing a deal that Prime Minister Narendra Modi is betting on to modernise the air force, a government source told Reuters.
The acquisition is part of a $150bn military overhaul India has launched, drawing global arms makers into one of the world's most promising markets.
Under the deal, India will get 36 Rafale jets ready to go straight into service. India's fighter aircraft fleet, comprising Russian, British and French planes, is down to 33 squadrons as against the air force's requirement of 45 to counter a "two-front collusive threat" from Pakistan and China.
The two countries will sign the final deal on Friday, the source, who did not wish to be named as he is not authorised to speak to the media, said.
French defence minister Jean-Yves Le Drian is arriving New Delhi on Thursday, the source said, to sign the deal with his Indian counterpart, Manohar Parrikar.
India, the world's biggest arms importer, had intended to buy 126 Rafale planes before several years worth of talks with Dassault broke down and Modi and France's President Francois Hollande stepped in last year to agree on the smaller purchase.
The value of the deal, which had been repeatedly held up as the two sides haggled over financial terms, was not immediately available.
Indian defence ministry officials have earlier said the value of the deal could be $8.5bn to $9bn.
The 90 planes not supplied via the original multi-role combat aircraft tender have meanwhile become the target of intense interest from other plane makers such as Lockheed Martin Corp and Boeing Co.
