What i understand of him is that he meant to say IAF is trying to gulp everything that come in their way without realizing what their true needs are ,
That may be because they now have big budget than ever before that may have hypnotized them verging them to grab whatever they can . I don't want to sound offensive neither i am , just to clarify to IAF lovers that may take my post as an offence without being rational to it .
Look at the types of aircraft IAF is operating . You can go with the names m2k,mig-29,mki, mig21, LCA, jaguars, mig-27. Now these are 7 types many may argue that they are going to retire soon but the question is they are still in service as of yet and what will happen tomorrow is still a far fetched thing specially the way your guys are going with MRCA . Even the USAF with its all might is not operating that many fighter types (not including the b-2s, sr-71s etc, just about conventional fighters).
The question is not about the modernization , they can modernize even by keeping the types less Look at the Saudi, Turkish, Israeli air-forces they have less fighter types but still effective and modern airforces even when Saudia has more defence budget than india. The thing is IAF is not willing to retire the old aircrafts as of yet just to maintain that status quo of having one of the largest number of fighter aircrafts. They would have easily satisfied with quality . Why not to induct systematically by replacing 2-3 old types with 1 new type rather then keep on increasing the types. The modernization can also be done with less types while more numbers while protecting the squadron strength as well ,
To maintain 7 different types of aircrafts may be easy in peace time but wouldn't it be a nightmare during war time
