as long as May and Might are used by OSINT, Experts and Journalists. Take those news with grain of salt. Here I am talking about Meteor. If Meteor could be integrated with LCA, then that missile could be integrated with Sukhoi too. After all integrating any 3rd party missile's biggest headache is to get required launch codes.
launch codes? What does that even mean?
Integration I'm afraid is a MUCH bigger thing that just getting required "launch codes" (whatever that means). The radar must be able to talk to the missile and provide it with target information.
If you can't do that then there is a very basic integration, like what the Americans have done for the Ukranian MiG-29s with their HARM anti-radiation missile. It simply means that the pilot fires the HARM in the general direction of an emitting radar and the HARM then tries to locate it on it's own. This approach is very inefficient, but is the only option available to them when integration with a Russian radar is not feasible or is going to take too much time.
Normal integration will require a data link in place for the radar to be able to communicate with the missile both before and after it has been launched. Without that, the missile won't work in LOAL mode (Lock On After Launch). And ideally, you want a two-way datalink where the missile provides updates to the radar after it has acquired the target as well in case the pilot wants to track it or re-assign a different target.
All this requires source code data for the missile manufacturer to be able to integrate their missile with the radar and vice versa for the radar to be integrated with the missile. MBDA won't give source code data for integrating Meteor with a Russian radar or even an Israeli radar is what we were told earlier by Livefist and other sources. Situation may change with Uttam radar on the Tejas Mk1A and possible Uttam variant on the upgraded Super Su-30MKI.
