The AFSC initiative is a collective endeavor by all NATO Allies to develop options for future multi-domain NATO surveillance and control capabilities after the retirement of the Airborne Early Warning and Control System (AWACS) fleet by 2035. The active contribution and commitment by individual Allies like Luxembourg have been essential to advance the project, NATO's first multi-domain surveillance capability, within agreed timelines and budget. Several Allies are actively contributing to the AFSC initiative through research, subject matter expertise and resourcing.
