I belatedly realised that
Jaguar GR.3 upgrades were
far too late for my
Hunter scheme. So I've revised it to
Harrier GR.3 systems exclusively.
As before, the upper image shows a minimal mod, the lower had the belly CFT. The latter now lacks the laser designation which probably means that the forward fairing could be detachable for gun access. [1]
As mentioned above, the ALQ-101 pod is seen mount on the outboard port pylon (Phimat would be to starboard). Just peaking out from behind the ECM pod is a
Paveway II LGB. The upper view shows rocket pods on the outer pylons - I suspect that these would have still been SNEBs (likely too early ofr the CRV7s).

... If you can incorporate a more powerful engine all the better.
Agreed ... although that wasn't part of the original brief.
There were surprisingly few British engines that would easily replace the 10,145 lbf
Avon 207 turbojet. At 43 inches diameter, the RB.168-1A
Spey Mk.101 was ~14.7 inches too big around to fit into a relatively unmodified
Hunter rear fuselage section.
The obvious, available candidate would be the then-new TurboUnion RB.199. I'm guessing that an unreheated RB.199 (RB.199-36?) would slip right in whilst saving weight. Add to that, commonality with the coming Panavia
Tornado. The downside is that the earliest RB.199s only produced 8,530-to-9,100 lbf without reheat.
There was an intriguing project - the RB.199-36 for the unbuilt HS.1189-1 and so-called A-10AMX. Some sources claimed that this engine would produce 14,230 lbf dry - a huge leap over the
Tornado GR.1's engine. Alas, I suspect that RB.199-36 output was listed in error ... other sources list 4,508 kg/s which works out to a more believable ~9,940 lbf.
