The MPRS fit is the same as on the French KC135Fs, albeit the French aircraft use the FR MK32 pod wheras the USAF use the Sergeant Fletcher version of the same pod - although I believe Sergteant Fletcher may well be owned by FR now. The pod sits right at the very wingtip out of necessity (due to the outboard engines). Consequently, it sits in the wing Vortex and needs an airflow deflector on the pod to cancel out the effect of the Vortex as well as an 80' hose as opposed to the 50' one normally fitted. I gather it makes receiving from it quite sporty at times - especially if you drift towards tthe centreline and catch the efflux from the engine.
