Baltic Air Policing

Baltic Air Policing is NATO's standing air-policing mission for Estonia, Latvia and Lithuania. It was established after the three Baltic states joined NATO in March 2004 and reflects the Alliance principle that airspace security is a collective responsibility. Because the Baltic states initially lacked the fighter aircraft and supporting infrastructure needed to maintain a continuous national air-policing capability, other NATO members provide aircraft, pilots and support personnel on a rotating basis. The mission is defensive rather than offensive. Its principal function is to maintain Quick Reaction Alert coverage, allowing assigned fighters to launch rapidly when unidentified, unresponsive or otherwise concerning aircraft approach or enter the airspace of the Baltic states. NATO combines fighter detachments with radar stations, communications networks, Control and Reporting Centres, Combined Air Operations Centres and other elements of the NATO Integrated Air Defence System. These systems provide continuous surveillance and command-and-control coverage and enable the Alliance to identify, monitor and, when necessary, intercept aircraft. For much of the mission's history, the principal operating location has been Šiauliai Air Base in Lithuania. Beginning in 2014, Ämari Air Base in Estonia became a second operating location, allowing NATO to distribute the mission across the region and increase its ability to respond. A normal deployment has generally included four fighter aircraft and approximately 50 to 100 support personnel, although the number and type of aircraft have varied according to the contributing nation and the security situation. Rotations initially followed a three-month schedule, while later deployments commonly used four-month rotations. The participating force has included aircraft from numerous NATO air forces. Hungary performed the mission for the first time in 2015, while Italy also took part in the 2015 rotation. Denmark, France, Germany, Poland, Spain, the United Kingdom and the United States have also contributed aircraft or supporting assets at different times. During the heightened security environment following Russia's annexation of Crimea in 2014, the United States reinforced its detachment with additional F-15C fighters and KC-135 aerial-refuelling aircraft. In January 2022, American and Danish fighters were deployed to detachments in Estonia and Lithuania as NATO enhanced its air-policing posture during the build-up of Russian forces around Ukraine. Training is an important part of the mission. NATO's Allied Air Command developed recurring regional exercises, originally known as Baltic Region Training Events and later as Ramstein Alloy, to improve interoperability among the deployed fighters, the Baltic air forces and regional air-control facilities. The exercises help standardize procedures and give crews experience operating across the Baltic airspace environment. The mission also depends on infrastructure investment. Estonia, Latvia and Lithuania have contributed to deployment costs, while NATO's Security Investment Programme has supported improvements at Šiauliai. In 2023, Latvia announced that Lielvārde Air Base would temporarily host NATO fighter aircraft during the 2024 reconstruction of Ämari. The arrangement illustrates the continuing evolution of the mission's basing model. Baltic Air Policing is not a commercial brand or an independent company. It is a multinational NATO operational framework whose visible outputs are air surveillance, rapid interception, deterrence and reassurance. Its importance increased after 2014 as Russia adopted a more confrontational military posture toward NATO's eastern members and remained central to the Alliance's regional air-defence planning.

Baltic Air Policing began in March 2004, when Estonia, Latvia and Lithuania joined NATO. The three countries did not yet possess the fighter fleets and associated support structure needed to conduct continuous national air policing, so NATO organized a rotational system in which allied air forces provide aircraft, aircrews and ground personnel. The mission forms part of NATO's wider air-policing architecture, which has developed since the 1970s around radar surveillance, communications, command centres and Quick Reaction Alert aircraft. Within this system, fighters can be ordered to investigate unidentified or non-communicating aircraft and protect the integrity of allied airspace. The Baltic mission is defensive and is intended to maintain sovereignty, deterrence and reassurance rather than conduct offensive operations. Šiauliai Air Base in Lithuania served as the principal base from the mission's beginning. Deployments initially rotated approximately every three months and generally involved four fighters supported by between 50 and 100 personnel. NATO later moved toward four-month rotations. In 2014, following Russia's annexation of Crimea and a deterioration in the European security environment, the Alliance expanded its Baltic arrangements. Ämari Air Base near Tallinn became a second operating location, beginning with a Danish deployment. The United States also reinforced its Šiauliai presence with additional F-15C aircraft and KC-135 tankers. The list of contributing nations broadened over time. Poland, France, Denmark, Germany, Spain, the United Kingdom, Italy, Hungary and the United States are among the countries associated with deployments described in the mission's history. Hungary participated for the first time in 2015, and Italy carried out a rotation during January to April of that year. The mission has also been used to support broader NATO readiness. In 2013, Baltic patrol aircraft were called upon during a training scenario involving a simulated Russian bomber attack against Stockholm when Swedish aircraft were unable to respond. Training and interoperability have been institutionalized through exercises organized by NATO Allied Air Command. Baltic Region Training Events, later renamed Ramstein Alloy, allow deployed crews to train with the Estonian, Latvian and Lithuanian air forces and local air-control facilities. These activities standardize procedures and improve coordination among aircraft, radar operators and command centres. The operating bases have required continuing investment. The three Baltic governments have contributed to deployment costs, and NATO's Security Investment Programme allocated funds for improvements at Šiauliai. The mission has also experienced operational incidents, including a 2011 mid-air collision involving a French Mirage and a Lithuanian L-39, a 2013 Danish F-16 bird strike, a 2015 German Eurofighter fuel-tank incident and the accidental release of an AMRAAM by a Spanish Eurofighter in 2018. In January 2022, during the Russian military build-up around Ukraine, NATO deployed American and Danish fighters to the Baltic detachments in Estonia and Lithuania as part of enhanced air-policing measures. In 2023, Latvia announced that Lielvārde Air Base would temporarily host NATO fighters during planned reconstruction at Ämari. These developments show how the mission has evolved from a capability-substitution arrangement into a durable element of NATO's eastern-flank air-defence posture.

  The mission maintains fighters and crews at readiness so they can launch rapidly to identify, monitor or intercept aircraft approaching Baltic airspace. The capability is supplied by rotating NATO members rather than by a permanent Baltic fighter fleet.

• Ramstein AlloyTraining and interoperability

  Ramstein Alloy is NATO's recurring regional training activity for deployed Baltic Air Policing crews, the Baltic air forces and air-control facilities. It evolved from exercises previously known as Baltic Region Training Events and is intended to standardize procedures and improve multinational coordination.
