Desh getting washed away with "development" - and you are focusing on narrow things....
BAF HQ will be built new to rival the Pentagon !! This museum will look like a village primary school in comparison.
Ashitecchey....Just watch. ;-)
In other more serious news, look at this. This guy is saying Bangladesh will be better off buying the used/surplus Mirage 2000N from UAE air-force which will be superb bang-for-the-buck...UAE air-force is getting new higher spec Rafales by 2026 and they will let go of the Mirage 2000s cheap.
While a bit far out as an idea, the value proposition can't be beat, especially if the French can give us a good price on engine overhauls and at least partial teardown overhaul for the avionics and flying surfaces maintenance for the Mirage bodies (C/D checks). Great for interim measure in my opinion. Whatever we order as MRCA is not getting anywhere near BAF bases until say 2028. These Mirage 2000N's could be good stopgap measure...
