There must have been some original plan to develop homegrown electronics. But this "need" can be covered with drones and FCAS so I don't see them finally procuring small numbers of A319 for this role now. And it makes sense to be NATO- and USN-style equipped. Still strange that they didn't get this going earlier with the Orions placed in between. They proved to be very expensive to get operational, got rewinged and such.
