Willard,
You've missed off the end of my sentence in your quote, which is what makes it relevant. For the MAA to sign off on something they like to understand it. When the technology is new (and admittedly the theory behind AESA radars is not) that has to be explained to them. Radar safety is a big issue that is just one of several addressed.
With Bob Work in the mix it will be interesting to see how X-47 and UCLASS develop.
