Flying straight and level to do guidance is asking for a missile up the butt.
Video says the missile was guided by the F-18.
Doubt it. F-18’s a chase plane, to watch missile, and shoot it down if it goes rogue.
This Tomahawk variant would be worthless if it needed an F-18 to guide it to a ship target. F-18 would get shot down.
PS. They called it Unclassified. I wouldn’t have. But they are hard up for successful bragging events. There is still valuable information in these video clips.
