Future Electronic Attack Aircraft

With the EF-111 Raven retired and the Navy/Marines EA-6B Prowler filling the
electronic attack role for all services - does anyone know what is planned
for the future in terms electronic attack aircraft for USAF to fill the role
once filled by the Raven?

It looks like the EA-6B will be replaced by an electronic attack version of
the super hornet (EA-18G Growler) - but will this be only for the USN/USMC,
or will it be a multi-service asset?

Does the USAF have anything in mind for a future electronic attack aircraft?
