Rahaâ€™s visit will begin with HALâ€™s MiG complex in Nasik on June 7, where Indiaâ€™s frontline fighter Sukhois (Su-30 MKI) are manufactured and overhauled. Sources said the air chief would visit the flight hangars, ROH (repair and overhaul) facilities, assembly line, machine shop, functional test labs and system test units. The air chief is also visiting the enhanced Kopyo (the radar used on MiG fighters) test lab in Nasik. Sources said the Sukhoisâ€™ cost escalation issue was unlikely to come up during Rahaâ€™s visit, since the matter was being taken up at the ministry level. The chief will also be updated on the technology advancements of the Nasik division, which is the nodal agency for integrating supersonic BrahMos missiles on Sukhoi. Currently a Sukhoi is undergoing system integration tests ahead of the flight trials with the air-launched version of BrahMos. The flight tests are set to begin in October and the missile is expected to enter the IAF rolls officially next year.
