I think goi ended kaveri pgrm, only kabini further development remain.Well with this tot hals experience will go up hopefully they can upgrade su 30mkis engine's but even if we can isn't testing engines is something we can't do here in India? Wasn't kaveri supposed to go to russia for testing but couldn't cause of war
No, this experience don't help any improvement, but helps mro, wartime maintenance, to understand manufacturing process of engine, & create jobs.
