Hercs with palletised mission cabins. Hang all sorts of gubbins off the outside of one of them.
Take old K model that doesn't have the life left etc etc to thrash around the desert, bouncing off dirt strips. Reduce fleet to 3 or 4, rewing those, rest used as a source of spares. Mount cameras, sensors etc etc on the outside. Roll on mission pallets as and when required. Yanks do it with their EC130s and we used to do it with Snoopy. ISO container type thing, full of sensor ops away you go. No performance issues - main base operations and AAR capable. Surplus K crews and techies convert to J. U/s J's sitting around can then be serviced and manned.
Genius. Do I win a bun?
