The encounter unfolded on 22 September 2026, when two Spanish EF-18M fighters identified and escorted a Russian surveillance aircraft over international waters in the Baltic. The aircraft had not filed a flight plan, and its transponder was off. It had not contacted civil air traffic control. The mission was the first rapid alert response, known as an Alpha Scramble, carried out by the Spanish Tactical Air Detachment "Ámbar" in Estonia. The Estado Mayor de la Defensa reported it through "X"; Spanish media, including Infobae España and Europa Press, later reported the operation.
The aircraft was outside national territorial waters and was reportedly approaching from the area of St Petersburg. Mundo América reported that it had not filed a flight plan. The Spanish fighters moved to identify and escort it as part of NATO's air-surveillance work in the Baltic region.
Baltic Monitor reported that the Spanish F/A-18s had been deployed to Ämari from 8 September 2026, alongside Turkish F-16s. The interception took place shortly after the detachment arrived in Estonia. NATO’s Combined Air Operations Centre in Uedem, Germany, coordinated the alert response. Mundo América reported that CAOC Uedem coordinates air-surveillance and air-defence activity in this part of the alliance’s eastern region.
Ámbar operates from Ämari Air Base in Estonia. The detachment helps monitor and protect airspace across the Baltic countries under NATO's Integrated Air and Missile Defence structure, known as IAMD. Its work also falls under NATO Enhanced Air Policing, the alliance's air-surveillance and air-defence mission in the region.
This was the detachment's first rapid alert response in its current deployment. The aircraft remained over international waters, so the reported incident did not amount to an intrusion into Spanish or Estonian territorial airspace.
Major Antonio Mancebo Marín commands the detachment, which includes personnel from several units of the Spanish Air and Space Force. The Ala 15, based in Zaragoza, provides the basic contribution. The Spanish contingent has 110 military personnel and four EF-18M combat aircraft. Its rotation is scheduled to continue until mid-October 2026, information from InfoDefensa.
The Alpha Scramble showed how the detachment's four fighters can move from their Baltic deployment into an active identification and escort mission when an aircraft does not contact civil air traffic control.
Spanish aircraft are operating alongside allied forces at Ämari, where Turkish Air Force F-16 fighters use the same base. Italy contributes separately to NATO's air-policing mission, with EF-2000 aircraft operating from Siauliai Air Base in Lithuania.
Spain's four aircraft are part of a wider allied arrangement. The Spanish contingent works alongside Turkish fighters in Estonia; Italian aircraft operate in Lithuania. Each national force operates within NATO's air-policing structure. Several allied detachments are now active in the Baltic region.
Coverage of Spain's international operations has also included festival coverage. This operation concerns a different area of public interest: a direct military response during a NATO air-surveillance mission.
The Russian surveillance aircraft approached from the St Petersburg area and was identified over international waters. It reportedly had no filed flight plan. Its transponder was switched off, and it had not contacted civil air traffic control. Two Spanish EF-18Ms escorted it. The response came from a 110-person Spanish detachment with four fighters based in Estonia, demonstrating Spain's active role in Baltic air defence through an operational deployment.
