Once again...just mounting a compatible rail doesn't solve the problem!if India gets into a shooting war with China the few hundred Meteor and Mica the IAF will have on hand won't be enough. It will be good to have an adaptable indigenous rail that can be mounted on Rafale when it runs out of French made ordinance.
Thales' radars (on both Mirages and Rafales) are still incompatible with both Russian Agat seekers and desi seekers onboard Astra missiles!!
