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 Indian Air Force the first in the world to have successfully tested such a type of air launched trisonic-class missile on a sea-based target. After the IAF successfully tested Brahmos from a Su-30MKI against a sea-based target, it declared on 17 December 2019 that the integration of BrahMos-A on Su-30 MKI is complete.
