US Air Force assessments suggest that the current fleet of ten EA-37Bs may be insufficient for future needs, with internal studies indicating a requirement for up to 20 aircraft. As reported by Army Recognition, proposals to expand the fleet to at least 14 aircraft have already appeared in congressional funding discussions.

Italy has received approval to acquire two EA-37B mission system packages for integration into its Gulfstream G550 fleet, marking early international adoption. Additional interest is reportedly coming from allies in the Indo-Pacific region.
