Royal Air Force Typhoons were scrambled on Monday to intercept two Russian aircraft over the North Sea.
The TU-142 'BEAR-F' aircraft had approached the northern edge of the UK area of interest, the RAF said.
The maritime reconnaissance aircraft were monitored by NATO partners and intercepted by Norwegian aircraft before being handed over to the control and reporting centre located at RAF Scampton in Lincolnshire.
The RAF Quick Reaction Alert (QRA) Typhoons were launched from RAF Lossiemouth near Moray, Scotland, and tracked the aircraft across the North Sea.
They were supported by Vespina, the VIP Voyager, that was deployed from RAF Brize Norton in Oxfordshire to provide air-to-air refuelling on the mission.
