RAF jets were scrambled to intercept four Russian bombers off the north of Scotland.
Typhoons from RAF Lossiemouth were sent from their base near Moray, as four Russian Bear aircraft approached the UK area of interest on Wednesday.
The mission was supported by a Voyager Tanker from RAF Brize Norton.
The RAF Typhoons escorted the Russian aircraft, which were two Tu-95 Bear H and two Tu-142 Bear F, out of the UK’s area of interest.
Quick reaction alerts are incidents that have occurred since the Cold War-era, and usually involve RAF crews shadowing military Russian aircraft flown near UK airspace.
The RAF has previously said that Russian planes often do not talk to air traffic control or “squawk” – broadcasting a code ensuring they are visible to air traffic controllers on the ground.
This incident comes amid rising tensions between Ukraine and Russia, as the prospect of a Russian incursion looms.
An RAF spokesman said: “Quick Reaction Alert Typhoon fighters based at RAF Lossiemouth supported by a Voyager from RAF Brize Norton were scrambled today against unidentified aircraft approaching the UK area of interest.
“Subsequently we intercepted and escorted four Russian Bear aircraft.”
Scottish Conservative MP for Moray, Douglas Ross, said: “The current situation between Russia and Ukraine is the focus of a great deal of attention and concern just now, but the launch of aircraft from RAF Lossiemouth to intercept Russian planes reminds us all of the major role our military personal here in Moray plan protecting not just the UK, but our allies across the world.
“This incident shows how important it is to the security and protection of the UK to have these facilities in Moray ready to act at a moment’s notice.
“With the current situation on the border at Ukraine, our world-class RAF were typically rapid in their response to keep our airspace and people safe from any potential threat.”
