To be honest, I cannot see any reason for that to be done. The vehicle is still classified and it is not built to be a mere escort. But it is not a fighter plane either in the conventional sense.

Also, it is very close to AF1, that is not allowed. The video is CGI-augmented.

In the article, the CVN-78 photo is Photoshopped. One can easily see that some objects have 'proper' shadows but others don't. The helicopter shadow is hard and dense, showing that the sun is not diffused by clouds or haze. The 'TR3-B' object shadow has very small errors that show it is not real. Because of the sun angle, the curved top edge should be casting an arced shadow but the shadow on that side is ruler flat and its overall density is really sketchy. Fake.
