RAF fighter jets intercepted Russian military aircraft in the North Sea near UK airspace, the air force said.
It marks the third time in six days the Typhoons have been scrambled in response to Russian planes.
The planes were identified as two Russian Tu-142 Bear F anti-submarine warfare and maritime patrol aircraft.
The Quick Reaction Alert Typhoons, flown by pilots from RAF Lossiemouth in Moray, were launched from Leuchars Station in Fife where the pilots are temporarily based.
The RAF said the Typhoon pilots monitored the planes “while in our area of interest to ensure the flight safety of all airspace users operating in this busy portion of international airspace”.
“At no time did the Russian aircraft enter UK sovereign airspace,” the force added.
