LO, I was very specific and careful to not say SAR is a unique capability to F-35 as I know fully well it isn't. The term unique refers to the ability of a 5th Gen platform such as the F-35 to operate "balls deep" in a battle space replete with varsity threat systems and conduct CAS, or any other mission within its design for that matter.
I also don't believe that you think for Congress so I challenge your opinion as to what those on the Hill "would have gathered" from Dunford's remarks. They are briefed to a much higher level than Aviation Week et al and smart enough to make their own minds up (cue typical politician cynicism).
You make an interesting point ref QE. Sadly I don't have the background.
