Inquisitor - the bid for additional 'Reapers' (we will rue the day that became the name!) is going through now, but they take time to build and we're in the queue.
You're absolutely correct in the idea of passing all information into a central hub to provide information to whoever needs it, but it has nothing to do with a CAOC. These are the imagery analysts required to interpret the various types of data coming off the system (FMV/EO/IR/SAR & MTI) that we're in very short supply off. Likewise there is no provision to purchase the equipment on which to do the analysis. Once again we've bought the shiney toy but forgotten the need to support it
Also, in order to have NEC we need a network - not a series of barely linked stove pipes.
