Highly unlikely, there’s nothing in the Yemeni arsenal (or most countries arsenals) with the range to target a US Navy AEW/AWACS asset (in the E-2 Hawkeye) in the rear lines like that. These aircraft operate hundreds of kilometres away from the frontlines. This would have to be a world record breaking Surface to Air Missile kill, or thereabouts, to even be possible. For context, the current world record in combat is 217km with an S-300V4 system. Maybe Ansarallah could have tried to rig up a surface to surface anti radiation missile with the required range (like the Hormuz missile with 300km range) to try hit an aerial target and try home in on the emissions of the big radome on the E-2, but I doubt it would result in a hit. Given that US airstrikes were ongoing hours after this reported attack, I can’t see this being realistic.
Also federation is back? Cool.
Why do you think the US wants Greenland, and has already signed deals with mining conglomerates there for rare earths for the US Department of Defence, preventing a Chinese buyout of these mines in the process?
