American F-15 combat aircraft flew into the 32nd Tactical Air Base in Łask, central Poland, on Thursday to take part in Nato's Air Policing mission in the airspace of the Baltic states.

Nato countries are supporting Estonia, Lithuania and Latvia, which lack warplanes able to patrol their airspace. The mission is currently in its 58th deployment, with Poland contributing its Orlik contingent for the tenth time.

"Today American F-15 fighters arrived at the Łask air base, where they will support the eastern flank within the framework of the Nato Air Policing mission," the Defence Ministry said on Twitter. The aircraft will stay in Poland until the end of February.

Baltic Air Policing aircraft are often used to identify Russian aircraft flying to and from Russia's Kaliningrad exclave. According to Nato, Russian planes often approach alliance airspace without communicating to flight control or submitting a flight plan, and with their localisation and identification transponders switched off.

The mission is controlled by Nato's regional multinational air force command in Uedem, Germany.
