How do you match the SA conferred by having a human brain and eyes on scene, with a wider field of regard than any sensor turret, and with a peripheral vision capability that allows easy detection of unplanned, unbriefed targets.
Even if you ignore the limitations of a datalinked sensor picture displayed on a video screen, and assuming that you can solve all of the problems with bandwidth, susceptability to jamming, etc.
Still think that there a UAV is superior than a manned platform for the majority of roles?
I don't.
