And there's the problem- it shouldn't be a choice of one or the other. Were it not for our wonderful procurement system, we should be able to put an ILS on every single aircraft in the entire USN-USMC inventory for what we spend on just a few EA pods.
Completely agree. HeyJoe showed me a really neat little box, the size of a Rubix cube, one day that did some stuff that a bigger piece of equipment regularly does. And the amazing part was that it was designed to plug into all the new airframes in the fleet (non-legacy).
And yet somehow, I still can't shoot a precision GPS approach with my nanometer-accurate INS system that's already installed.
