That was a very different RFP. The title stated "Tender (AP-2 Russia)" while the specs listed were very specific to the point it was obvious only Su-30 and Su-35 were allowed to compete.Isn't that what happened with the original MRCA tender.
Limit yourself to a Russian platform.
And then watch them attempt to rip you off with the price.
Please tell me Bangladesh isnt that stupid.
Open the link above and have a read of the attack helicopter RFP: 90% of the criteria is undecided.
