ABOUT

STEADFAST DEFENDER 2021 is a collective defence exercise based on an Article 5 scenario. The exercise will enhance Alliance security by maintaining NATO’s broad range of interoperability and military capabilities to deter potential adversaries and assure Allies of NATO’s ability to defend them. The geographical locations of the exercise and the scale of deployment across sea, land, air and the range of military capabilities involved reflect NATO’s resolve to deter, and where necessary, to confront and defeat, potential aggressors.
