"That's the same approach to precision as the JDAM.
It works quite well in that application." Right, but the issue is EW GPS jamming & spoofing:
- A normal "dumb" artillery shell will land within a certain radius from its target.
- A normal artillery shell equipped with GPS guidance will land much closer to its target.
- But an artillery shell equipped with GPS guidance that's been jammed/spoofed can be redirected to hit its own troops.
That's the issue our best equipment is intended to prevent.
