its own version of BrahMos by 2012. On 10 January 2009, it was reported that two Indian Air Force Su-30MKI fighter jets were sent to Russia for a retrofit program that would enable them to launch the missile. On 8 August 2009, Alexander Leonov, Director of the Russian Machine Building Research and Production Centre, said "we are ready for test launches." He also said that a new takeoff engine for the launching of the missile in air and at extremely high altitudes had been developed, and the initial test firing of the missile would be undertaken from the Su-30 MKI but did not specify the dates. On 26 February 2012, A. Sivathanu Pillai said that the air-launched version of BrahMos is being developed and will be tested by the end of 2012. This version of the BrahMos missile will use air-breathing scramjet propulsion technology and would be more fuel-efficient than a traditional rocket-powered missile. The purchase of over 200 air-launched BrahMos supersonic cruise missiles for the IAF was cleared by Cabinet Committee on Security (CCS) on 19 October 2012, at the cost of . This would include funds for the integration and testing of the BrahMos on Su-30MKI of the IAF. As per this plan, the first test of the air-launched version of the missile was to be conducted by December 2012. Two Su-30MKI of the IAF would be modified by the HAL at its Nashik facility where they will also be integrated with the missile's aerial launcher. A demonstration flight was carried out at Hindustan Aeronautics Limited Nashik on 25 June 2016 as a modified Su-30MKI carrying BrahMos-A underwent a successful trial flight, the first time a heavyweight supersonic cruise missile had been integrated on a long-range fighter aircraft; the project to adapt the weapon for air launch was approved in 2011, but was bogged down with technology transfer and intellectual property rights concerns. To carry the missile, the Su-30MKI undercarriage had to be strengthened, which also required new hard points and structural modifications. The cost of adapting the BrahMos for air launch was "phenomenal," but efforts to downsize the missile were abandoned after an attempt to reduce the size of the ramjet. On 22 November 2017, the missile was successfully test fired for the first time from a Sukhoi-30MKI against a sea-based target in the Bay of Bengal. This made the Indian Air Force the first in the
