NATO Assurance Measures
The assurance measures are a series of land, sea and air activities in, on and around the territory of NATO Allies in Central and Eastern Europe, designed to reinforce their defence, reassure their populations and deter potential aggression. These are a direct result of Russia’s aggressive actions in Ukraine. All 28 Allies are contributing to these measures on a rotational basis. The measures can be stepped up or reduced as necessary, depending on the security situation.
Since May 2014, NATO has increased the number of fighter jets on air-policing patrols over the Baltic States, and deployed fighter jets to Romania and Poland. Allies have deployed aircraft to Romania for training purposes. The Alliance has also commenced regular AWACS surveillance flights over the territory of its eastern Allies, and maritime patrol aircraft flights along the eastern borders of Allied territory.
To provide assurance at sea, NATO is deploying a number of multinational maritime forces such as a Standing NATO Mine Counter-Measures Group patrolling the Baltic Sea and the Eastern Mediterranean, and an enlarged Standing NATO Maritime Group conducting maritime assurance measures in addition to counter-terrorism patrols.
NATO is also increasing the number of exercises it organises. Military exercises provide important opportunities to improve the ability of Allies and partners to work together and are a valuable demonstration of NATO's readiness to respond to potential threats. These exercises take place on land, at sea and in the air with scenarios based on collective defence and crisis management.
