What if we were to push money into Typhoon as our multi-role fighter and keep Harrier as our 'niche' capability that is readily deployable and can operate from much smaller strips and with a much smaller footprint than the Tornado?
Binning the GR4 would save more money and leave us with a capable and flexible FJ fleet. Admittedly there may be a few ruffled feathers in the navigator community!
