If I'm the chief of BAF. Any adequate 4th gen fighter (1 squadron)+ AWACS+MRTT if possible is enough.
Let me explain in details once and for all.
First and foremost, Russia is out of option.
Secondly, if we want to buy from J-10C from PRC, then we have to buy at least two squadron (32x) to match Myanmar AF fire power. (They have 50+ 4th gen fighter)
But then there is that sufficient possibility of PRC double crossing us in any future conflcit with Myanmar.
And this is based on previous experience.
And then of course, there is that Rohinga crisis, in which they are in bed with Myanmar.
China was the front runner for Navy's ongoing frigate program.
But Rohinga Crisis was one of the reason Bangladesh started to looking at other options. (Along with the plan to move toward NATO standard as much possible)
But most important of all, the immediate consequence of such purchase from China is likely to be that our Big neighbor India would be extremely irritated if we buy such advanced Chinese platforms in that numbers. It will have geopolitical consequences that Bangladesh does not want to avoid. (For understanble reason)
Hence our only logical option is West.
That is the geopolitical aspect of this.
From a technical point of view, for now even Just one squadron will Eurofighter trench 4 will give us qualitative overmatch against Myanmar air force.
Also, it will be the first step in developing credible deterrence against our big neighbor.
Becuase otherwise Chinese J-10 does not have qualitative match for Rafale that India will soon induct in numbers under MRFA program.
About AWACS, it is doubtful if we need one. And when it comes to tanker, we definitely don't need that.
