Back in post 102, NoVANav said, "Essentially, except for some minor comm and equipment changes, they (the RAF RJs) will be the same as the USAF Rivet Joints. Back end mission equipment will be to the same standards".
Now that's fine but I have a recollection that one of the successes of the R1 was that it had different capabilities to the RJ and so could be used to complement each other and fill in for each other's gaps in sensor performance. If the RAFs RJ are now the same as the USAFs then presumably the previous gaps in capability will remainand cannot be filled by complimentary systems??
