NEW DELHI – India’s largest company by market capitalization, Reliance Industries Ltd., and France’s Dassault Aviation have signed an initial pact to work together in the Indian defense and homeland security sector, a Reliance official says. The agreement comes less than two weeks after Dassault emerged as the lowest bidder for a multibillion-dollar order to supply 126 Rafale fighters to the Indian air force. Indian Defense Minister A. K. Antony said it was a long process and the deal was not expected to be signed in the current financial year.

Indian low-cost Go Airlines (GoAir) has selected Pratt & Whitney PurePower PW1100G-JM engines for its firm order of 72 A320 aircraft. The agreement represents 144 firm-order PW1100G-JM engines and is expected to include a PureSolutionSM maintenance package, a spokesman for P&W, says. No financial details are available, but the spokesman says the deliveries are scheduled to start in 2016.
