I think you're not aware that BCG is already on the way to getting its own air wing..... its official....
when the Castle-class was converted to corvettes, most didn't notice.... but when the Minerva-class was given to the BCG, everyone noticed.... this was deliberate.... this is a message that BN knows the grammar of defining ships.... Durjoy-class broke all grammar.... it doesn't fall under any current definition (defined by Western thinkers).... especially when Indian corvettes are armed with 16 AShMs (for God knows why), Durjoy-class simply confused the big powers operating in the Indian Ocean.... BN is not following others' grammar.... its creating its own.... and others would have to react to it.... interestingly, they don't know how....
the term "patrol craft" didn't exist before WWII.... same for "OPV".... gunboats/ASW whalers/motor launches were renamed as patrol boats after WWII.... corvettes were renamed as OPVs.... frigates were defined during WWII following the definitions of "sloop", "corvette" and "destroyer escort".... and again, destroyers got redefined after WWII and even more during and after the Cold War.... up to a few years back, only the Western thinkers wrote definitions, and others followed.... its changing now...
rather than sticking with definitions, focus needs to be put on the purpose of ships.... BN is not following others' orders now.... so, its more likely that they won't follow others' definitions as well....
