Q about the AGM-142 "Raptor"

[thatguy96]

There is a weapon in both the USA and USMC Obats called the "AGM-142 Raptor" (weapon 214 in the USA Obat and 222 in the USMC Obat). It is a PGM commonly used by SEAD aircraft in both Obats. After reading this it doesn't seem to be a weapon designed for SEAD so I'm curious as to why the decision was made to make this the improved weapon for this role when the AGM-88 does not even have a successor in public development. I've noticed a number of inconsistancies with US SEAD aicraft in general, but I thought I'd pose this question as it is the one I find most curious.
