Justin Bronk, a combat aviation expert at the Royal United Services Institute, said: “The major drawback from not having the ability to supercruise in this case would be having to choose between using a great deal of fuel to go supersonic or stay subsonic and accept shorter effective range from the fighter’s missiles and an inferior energy position compared to a supercruising opponent.”
