They are very potent and effective combat platforms. But you need to build up a support infrastructure that would make these platforms absolutely ruthless. BAF needs to first invest in effective ground controlled radars, AWACS and then create an effective C4I network that allows all these Assets to speak to each other to create a comprehensive picture of the battlefield. You need to be able to look deep inside the enemy territory to muster your own response. In 1967, Israelis decimated 70% of the Egyptian Air Force before it could even take to the skies. Second, you need to invest in platforms that are dedicated for Electronic Warfare. In today's aviation combat, electronic warefare is the name of the game. Third, you would need to invest in hardened shelters to ensure your assets are protected if the enemy decides to launch overwhelming cruise missile strikes on your Airbases. Fourth, BAF would need to engage in massive training of not only its officers but the ground and support crew. That is why i said, it would take decades before BAF can build a force that could muster a credible defence against the IAF.
Overall, BAF would need to invest on force multipliers and build the necessary infrastructure to protect its assets. If you look at the PAF, its combat platforms such as JF17 and F16 are inferior to the SU30MKI, but what levels the playing field are the force multipliers that PAF can field. On Feb 27, it were the force multipliers that won the day for PAF as they injected steroids into the capabilities of the JF17's and F16's.
