The upgrade is being carried out by Russian agencies in collaboration with the Hindustan Aeronautics Limited (HAL). This reported by Sputnik agency. "We will start the Su-30MKI upgrade program as soon as possible to bring in new weapons and avionics to make the fleet more potent," T Suvarna Raju, chairman and managing director of HAL said on Monday. Sources told Sputnik that the entire fleet of 272 fighter jet will be upgraded and equipped with advanced weapon systems such as Brahmos supersonic cruise missile, higher range infrared homing system of R-27P and 100 Kilometers range missile R-77. The two-stage modernization program will cost approximately US $6 billion. "When it comes to technology transfer, the Russians offer everything without any strings attached. The IAF would look forward to continuing its engagement with the Russian aviation industry for the enhancement of Su-30 upgrades so that it could be more potent," Vice Chief Air Marshal S B Deo, Indian Air Force said at a seminar to celebrate 70 years of India-Russia diplomatic relations. Earlier this year, Russia's Unique Engine Corporation had offered a whole new engine for the fleet. "We have developed a better successor to the AL-31F engine based on a new design and has been offered to IAF as part of the upgrade package," Alexander Artyukhov, the director of United Engine Corporation, had told the media at Aero India 2017. The AL-41F-1S is a brand new engine, which produces 18 percent more thrust than its predecessor.
