IAF went a decade without any jet trainers. Inexperienced pilots went from cessnas (or the Indian equivalent), to badly maintained 50 year old MiG 21s.It's not hard to send a small contingent of studs to represent the force.
They can't train that hard if IAF is constantly short on smart munitions.
I remember reading about an incident where the Indian pilot wind up bombing his own base while trying to preserve the munition which failed in training. Memory hazy and can't find a link, but it could've been a fuel tank.
You can't train if you don't have the planes. If Indian sortie rates are low, then available airframes for training is low. If they have big flight hours, then it's probably a administrative stats game.
Maybe the Indian airforce have suddenly improved things in the last 10 decades and buying competent platforms makes them a competent force. But given how everything else goes in Indian society I'm very sceptical.
