IAF is betting on Rafale and Rafale M. If IAF purchase this in high number then there won't remains enough fund to drive AMCA and ORCA-TEDBF program. These program will be delay then IAF will again look for new foreign Jet.. Cycle continues.India should have given green light to Tejas Mk 2 and AMCA right after Tejas IA FOC because India signed contract for 99 GE F-414INS6 engines about a decade ago with about 50-60% TOT.
Main issue is decision making from bureaucrats and allocation of fund on time. First time Jet development is always takes time. But we have to promote it. With Imported Jet India won't get technical expertise, forget ToT.
