If you are genuinely suggesting that the paper programme currently called Scavenger can get close to replacing the MRA4's capability (or for that matter MR2's capability) you are:
a. T** Mc****
b. A BWoS senior neddy
c. Deluded
d. Living in cloud cuckoo land
e. All of the above
Not before 2030 (at the earliest). And not without a massive financial injection. UAVs are not the panacea that some of the senior airships think they are. They appear to be guilty of being seduced by the unproven, untested, in fact not yet designed, shiny, shiny.
