The MiG-29's good operational record prompted India to sign a deal with Russia in 2005–2006 to upgrade all of its MiG-29s for US$888 million. Under the deal, the Indian MiGs were modified to be capable of deploying the R-77RVV-AE (AA-12 'Adder') air-to-air missile. The missiles had been successfully tested in October 1998 and were integrated into IAF's MiG-29s. IAF has also awarded the MiG Corporation another US$900 million contract to upgrade all of its 69 operational MiG-29s. These upgrades will include a new avionics kit, with the N-109 radar being replaced by a Phazotron "Zhuk-M" radar. The aircraft is also being equipped to enhance beyond-visual-range combat ability and for air-to-air refuelling to increase endurance. In 2007, Russia also gave India's Hindustan Aeronautics Limited (HAL) a licence to manufacture 120 RD-33 series 3 turbofan engines for the upgrade. The upgrade will also include a new weapon control system, cockpit ergonomics, air-to-air missiles, high-accuracy air-to-ground missiles and "smart" aerial bombs. The first six MiG-29s will be upgraded in Russia while the remaining 63 MiGs will be upgraded at the HAL facility in India. India also awarded a multimillion-dollar contract to Israel Aircraft Industries to provide avionics and subsystems for the upgrade.
