i think its necessary ..becoz it will make hal in to fight or die situation they are behind schedule every time ,the ifr flights has to be done in 2017 april till now its not done , gun trails in nov dec of 2016 ,every thing hal done in pathetic way , i like tejas more than any fighter even it small it pack a punch for it size and formidable power against jf17 , and to those who think tejas is not gud as f16 ,tejas is not medium weight fighter its a replacement for mig21 , and it was very suitable ,why we need long range medium weight fighter more ?now we have almost 300+(in mig29 upg,m2000-mk2,su30) what we need point in line fighter to make rapid action and high serviceability ..i think if hal rectify their mistake and speed up production of mk1 and mk1a development also mk2 tejas will be more than enough for iaf
the thing India need not some 70's us tech what we need 5 gen fighter other wise when we induct 5th gen it will be too late , either su57 or f35 its up to mod to decide (amca not going to see the sky before 2030 ..assumption form last decade ada and hal behavior )
also gov have to stop spending unnecessary fund in r&d in drdo and ada and support priv8 r&d ,,, in Indian mind gov job is life long insurance they dont have any competitive mind whether they succeed or not they will get paid less efficiency and lot of bureaucracy
