Maybe but definitely not within 5 years time. BD has no budget for more modern sub and these sub are aiming at Myanmar rather than IN. Myanmar navy has no single submarine. It will gives BD an edge for them in many coming years.
But these will all changes if Myanmar buys submarine. They have one of the fastest growing economy and may have the money to buy sub.
My friend you may be surprised how much BD can afford these days.
BD economy is 230 billion US dollars and is growing at over 7% a year. With friendly repayment terms BD can afford to buy billions of dollars of Chinese arms over the next 5-10 years.
I think BD's next submarines will be 2 modern Chinese diesel submarines.
