Read quite a while ago that those block 52s with the ‘dorsal
spine’ houses the extensive SPS-3000 EW
suite(don’t really know how true; some say its the CFTs). Also,
these birds seems to have more ‘stuff’ poking out around it’s
airframe compared to US counterparts(probably sensors?). However,
are all our block 52s of this standard or only the latest batch? If
it is true, I guess our F16s are one of the most sophisticated in
the world.
