No problems, it's easy to manage.Then it depends on when the new gen equipment will be introduced. Because the IAF is not going to accept a barebones aircraft and then integrate new equipment as they become available. Whatever comes with the aircraft the first time is what the IAF will be stuck with for a long, long time. Only new additions will be accepted, replacements will not be accepted.
I mean, if Dassault sells the IAF the F3R configuration and then say let's replace all the existing equipment with new F4 equipment, then that's not going to happen. An entirely new contract is needed to change equipment. Or the alternative is Dassault simply switches the old with the new at the same cost. That's what the Israelis did with the Jaguar's radar, when they decided to deliver AESA radars at the same cost as the MS radars.
