These are warplanes - you don't want critical systems reliant on satellites that could be jammed, or downed, during wartime, which I suspect is why they don't do this already.

But fighters do use GPS. Daily. They use it for accurate navigation. But they do not absolutely depend on it.

But...

>>> Just make the plane use GPS.

...implies you would make them absolutely depend on it. Military aircraft use GPS daily, because it's cheaper and better. However, they also have accurate inertial navigation systems as a backup, so they can still operate effectively if the enemy makes GPS unavailable.
