NATO's Baltic Air Policing mission has been ongoing since 2004, but the RAF has never been deployed to Estonia - until now.
RAF Typhoon jets operating in the country are continuing to intercept Russian military aircraft near Baltic airspace.
In an exclusive Forces TV report, Laura Hawkins went to see what's involved in the mission.
These patrols come amid rising incursions by Russian aircraft with both bombers and fighters being tracked crossing into European airspace.
