LJ hits the nail on the head in all respects. There are on "whys" or "whats" left, the EF was the SEAD platform of the day. Politics, again, denied its use. How moronic.
The other big factor for the potential success of the platform for SEAD was the relocation of the forward RHWR antennae from the fin to wing nibs. That gave the platform the ability to resolve the position of emitters with huge accuracy.
Thanks for your excellent input LJ.
