I’d like to see a comparison of the maintenance schedules of the 2 aircraft types. I find it hard to believe that a business jet is going to be cheaper to operate than a relatively unsophisticated turboprop.
I notice that the wings appear to be lengthened on the jet. Perhaps an indication of a higher cruising altitude?
The phased array radar will be much more reliable and easier to maintain than the UHF rotating radar array on the Hawkeye...
