What this campaign was
Baltic Air Policing from 2004, with fighters Allies volunteer four months at a time under Allied Air Command's direction; from 1 August 2026 NATO's air defence mission, on the same bases and rotation with a wider mandate. It is the case that separates NATO direction from national command.
This is the mechanism through which the Alliance is continuously present in the airspace where its most frequent friction with Russia occurs, and it is the reason an air command, three operations centres and a set of host air bases sit in this module's Force Atlas. It is also the module's working example of a standing NATO activity that confers direction without transferring command — the distinction that governs every command edge here.

Summary
When Estonia, Latvia and Lithuania acceded in March 2004 they had no fighter force with which to police their own airspace, and NATO took on the task. Allies that possess the required capabilities volunteer aircraft, and the responsibility rotates every four months. Participating fighters have been based at Šiauliai in Lithuania since the mission's deployment; since 2014 NATO aircraft have also been based at Ämari in Estonia, and since 2024 Lielvārde in Latvia is capable of hosting them. Allied Air Command at Ramstein oversees the mission with 24/7 command and control from three combined air operations centres whose areas of responsibility overlap; when an interception is required the relevant centre decides from which base aircraft are scrambled. As part of the assurance measures introduced after 2014, Allies supplemented the existing air-policing forces in the Baltic states, deployed additional aircraft to Poland, and augmented the national air-policing capabilities of the Bulgarian and Romanian air forces. Since September 2025 the Eastern Sentry activity has deployed further assets that complement air policing along the flank. At the Ankara summit on 8 July 2026 Allies agreed to upgrade Air Policing and integrate it with other activities into a comprehensive NATO Air Defence posture, and in the Baltic states the air defence mission replaced Baltic Air Policing on 1 August 2026. NATO describes Air Policing as having been oriented to threats from aircraft, intercepted by fighters, and Air Defence as adding sea- and surface-based air and missile defence and counter-drone systems against crewed and uncrewed aircraft and cruise missiles. The four-month rotation continues from the same three bases; Estonia's defence ministry says Ämari becomes a designated NATO operational air base and that rotations for three years are agreed. NATO states that SACEUR has overall responsibility for the conduct of NATO Air Defence.
Stated objectives
What the participants say. Each entry cites where the position was stated; Vigil records that it was made, not that it is true.
To preserve the integrity of Allied airspace by monitoring and patrolling the skies of Allies that lack the capability to do so alone.
NATO's own statement of the mission's purpose, as air policing.
To protect against a full spectrum of air threats — crewed and uncrewed aerial systems and cruise missiles — with quick-reaction fighters, sea- and surface-based air and missile defence and counter-drone systems, within NATO's integrated air and missile defence.
NATO's statement of the mission's purpose since the 2026 move from Air Policing to Air Defence. NATO names the capability classes, not which national systems serve the mission.
Assessed objectives
Vigil's reading, graded. Kept structurally apart from stated positions so an assessment can never be published as someone's declared aim.
The mission's continuity, rather than its size, is what it contributes: a permanent allied presence in the airspace of states that joined without one, sustained across two decades and unbroken by the changes of 2014 and 2022.
Primary forces
- Allied Air Command Primary force · Confidence: High · as of 2025-10-24
NATO states that Allied Air Command "oversees the NATO Air Policing mission with 24/7 command and control from three Combined Air Operations Centres".
Supporting & external
- Combined Air Operations Centre Uedem Supporting force · Confidence: High · as of 2025-10-24
One of the three centres that plan, direct and coordinate allied air forces and decide which base scrambles for an interception.

Allies provide aircraft and assets "under SACEUR's direction" — NATO's own word, and deliberately not operational control. NATO's 2026 page states that SACEUR has overall responsibility for the conduct of NATO Air Defence; it still names no doctrinal transfer of command.
Outcome and present status
Running continuously since 2004. Its adaptations were additive until 2026 — more basing options in 2014 and 2024, supplementary assets after 2014, complementary capabilities under Eastern Sentry from September 2025 — and on 1 August 2026 it changed form: the same rotation and bases, conducted as an air defence mission with a wider mandate and, by host ministers' account, wider pre-authorised engagement.
Political implications
Rotation means the mission's continuity depends on Allies volunteering aircraft four months at a time, which makes it a recurring political commitment rather than a settled one.
Military implications
The fighters provide presence, identification and interception, and since August 2026 NATO tasks them as part of an air defence mission. What the mission's name does not establish is the ground layer: the surface-based and counter-drone systems that make air defence more than fighters are largely national, at very different stages of delivery, and NATO does not publish which of them serve the mission.
Linked events
Locations
Places this module already publishes as map markers, listed because the campaign is about them. Not an operational area.
What remains unknown
- NATO has not published the rules of engagement or the delegation of authority under the air defence mission. That SACEUR received broader authority and pilots pre-authorisations is the Estonian defence minister's account, and the Ankara summit declaration does not mention the change.
- NATO publishes no current detachment roster, aircraft numbers or basing assignments for the mission, and none is carried here.
- Scramble and intercept totals are published by some Allies as annual aggregates and by NATO not at all. They are not a Vigil series: counting NATO's responses would measure allied activity, not Russian activity.
- The doctrinal label for the command relationship is not published. NATO says direction and command and control; no source reached uses operational control or operational command. The framework nations' own press material states that national command authority over the aircraft is retained, which is a national statement and is cited as one.
- NATO's air-policing page is dated October 2025 and establishes the host bases and their dates, not which detachment is present now; the module's airbase records say which they carry, and this record inherits that limit.
Readings the evidence also supports
- The mission's longevity could be read as institutional inertia rather than as continuing necessity. The 2014 and 2024 basing additions, and the 2025 supplementation, are evidence against that reading but do not settle it.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
Whether the four-month rotation model changes
The 2026 change altered the mission's mandate, not its rotational basis, which NATO says continues. A move to persistent basing of fighters would be a further change of kind.
What the air defence mission actually adds in the Baltic states
NATO says Eastern Sentry's assets have been integrated into NATO Air Defence along the flank and names capability classes only. Which ground-based and counter-drone systems serve the mission in the Baltic states, and under whose command, is the open question.
