Isn’t Protector going to have SAR/MTI fit? (RPAS not my area, so I’m a bit out of the loop). If so, I suspect you might get similar or better given the longer loiter time than a manned platform. There’s more than one way to skin the battlefield surveillance cat, but from a parochial point of view it’s never great seeing sqns going.
All that said, I never understood why we never made more from our collective RW fleets in terms of battlefield reconnaissance and reporting. With a bit of clever thinking it wouldn’t be hard to equip all RW with sensors to make use of the fact that they operate close to the forward edge of the battle space and conceptually you would just be updating the former spotter / recce role we used to do anyway.
