HPM weapons are short ranged, and one of the things new aircraft are tested for is their ability to withstand massive levels of EMI or a full up EMP.
When the X-47B was tested, they measured the highest level of EMI on the deck of a carrier, then put the aircraft into an anechoic chamber, and hit it
with 2,000 times that level.
Even if there was a disruption system, the weapons released by the aircraft would far out range them. The explosions may tell you that you're under
attack, but nothing about where the attack came from.
As for GPS, that's what an INS backup system is for.
