An RAF Typhoon fighter jet and a supporting Airbus Voyager tanker plane were sent out from RAF Lossiemouth in northeast Scotland just before 3pm.
A French fighter jet and its supporting tanker plane were also sent up.
Radar data images from AirLive, which shows all aircraft in the air around the world, showed the four planes over the North Sea.
The Ministry of Defence said the jets were scrambled as the Russian Blackjacks long-range bomber jets were not talking to air traffic control, making them a hazard to all other aviation.
After about half an hour, the two fighter jets and the French tanker started returning to base.
About 15 minutes later the British tanker aircraft followed.
Almost a month ago a pair of RAF fighters jets were scrambled from south-eastern Romania to the Black Sea to head off two Russian aircraft which were believed to be Su-30 fighters.
An RAF statement said the jets were sent out to deter Russian aggression and to reassure Romanians of the UK’s commitment to collective defence.
A few days before that six Russian bombers were intercepted by RAF fighters in the same area of the Black Sea.
