A resprayed RAF Voyager used to transport the Prime Minister and the Royal Family has been called out to support military aircraft in Scotland, the Ministry of Defence (MOD) has said.
A week after returning to the skies after being painted with the Union flag, the aircraft joined the Quick Reaction Alert (QRA) with fighter jets from RAF Lossiemouth.
An MOD spokesman said the plane was deployed as Russian aircraft approached UK airspace.
No interception was required during the operation and the Voyager made a return to its base at RAF Brize Norton in Oxfordshire.
"Typhoon fighters from RAF Lossiemouth were scrambled today in response to Russian military aircraft approaching the UK however, the aircraft did not enter our area of interest and no intercept was made," an RAF spokesman said.
The RAF Voyager was launched to conduct air-to-air refuelling during the mission, the RAF said.
RAF Voyagers are also used to transport personnel or freight.
The aircraft recently underwent a makeover worth "around £900,000" in Cambridgeshire.
It saw the aircraft transformed from grey to bright white, with a Union Jack flag along its tail.
The move was condemned by opposition politicians, with the SNP describing it as an “utterly unacceptable use of public funds”.
Downing Street argued the makeover represented "value for money".
