Aircraft from RAF Marham in Norfolk have arrived in eastern Europe for a NATO mission.
F-35B Lightning aircraft are at Ämari airbase in Estonia to carry out NATO enhanced vigilance activity, a patrol mission in response to the Russian invasion of Ukraine.
The mission was announced on Friday, March 4, and an RAF spokesman said: "This activity provides air policing of NATO airspace ensuring a robust response to the Russian aggression seen in Ukraine and further contributing to the security of Europe."
The F-35s are supported by RAF Voyager air-to-air refuelling aircraft from RAF Brize Norton, which offer additional fuel for the jets giving them greater range and endurance.
The F-35B Lightning is a single-seat stealth combat aircraft intended to offer air superiority and perform strike missions.
