NATO has broadened the Baltic mission from identifying and escorting aircraft to actively defending allied airspace, giving pilots authority to destroy threats as drones and Russian military activity change the operational threshold on the north-eastern flank.

NATO has upgraded its Baltic Air Policing mission into an air-defence operation, a significant change that moves the Alliance beyond the peacetime interception model used over Estonia, Latvia and Lithuania since 2004.

Lithuanian President Gitanas Nausėda said the revised mandate gives pilots broader authority, including the ability to destroy threats. The announcement turns a political demand repeatedly made by Baltic governments into an operational change in how NATO protects the region.

From identification to defence

Traditional air policing is designed to preserve the integrity of allied airspace in peacetime. NATO’s description of the Baltic mission emphasises rapid launches to identify aircraft that fly without transponders, flight plans or contact with civilian controllers, and to escort them where necessary.

Air defence is a harder task. It assumes that an object may be hostile and that commanders need authority, sensors and weapons to defeat it before it reaches a target. Rules of engagement must support decisions made in minutes, often with incomplete information.

The change follows repeated drone incidents and growing concern about low-flying threats. Defence Matters reported when NATO fighters shot down a drone after a Latvian airspace alert, an episode that exposed the limits of using expensive combat aircraft against smaller unmanned systems.

Authority does not create capacity

Giving pilots permission to act is necessary, but it does not solve the Baltic air-defence gap. Fighters can intercept aircraft and some drones, yet they cannot provide persistent protection against large mixed attacks involving cruise missiles, ballistic missiles, decoys and unmanned systems.

The Baltic states need a layered network: long-range radar, passive sensors, electronic warfare, short-range counter-drone systems, medium- and long-range surface-to-air missiles, hardened command posts and reliable links to allied aircraft.

Identification remains crucial. A drone may be a deliberate attack, a reconnaissance platform, a civilian object or an aircraft diverted by electronic warfare. Destroying it too late risks damage; acting too quickly can create escalation or endanger civilian aviation.

NATO’s existing air-policing procedures place launch decisions with Combined Air Operations Centres. An air-defence posture requires those command chains to handle a wider range of threats and potentially delegate action more rapidly.

Russia will test the boundary

Russian military aircraft regularly operate between mainland Russia and Kaliningrad near NATO airspace, often without the practices expected in busy civilian corridors. Moscow also uses electronic warfare and ambiguous aerial activity to create uncertainty below the threshold of open conflict.

The revised mission may strengthen deterrence by making clear that incursions can be met with force. It may also invite probing designed to reveal radar coverage, reaction times and rules of engagement.

For that reason, the upgrade needs disciplined public communication. NATO must deter without suggesting that every unidentified contact will be destroyed. The operational standard should be credible defence based on threat assessment, not automatic escalation.

A regional model for NATO

The Baltic change reflects a wider shift along the eastern flank. Poland and Romania repeatedly activate aircraft during major Russian attacks on Ukraine, while drone incidents have forced NATO governments to reconsider the boundary between policing, vigilance and integrated air defence.

The new mandate is therefore more than a regional adjustment. It recognises that peacetime interception procedures are insufficient in an environment where drones and missiles can cross borders quickly and attribution may be contested.

The measure will be meaningful if it is matched by more sensors, ground-based systems, trained crews and sustainable rotations. Broader authority can close a legal and command gap. Only deployed capability can close the air-defence gap itself.
