The RAF scrambled two Typhoon fighter jets to Lithuania on Friday to track a Russian spy plane, accompanied by two Russian fighter jets.
This latest incident has increased tensions as the Russian President Vladimir Putin has upped military exercises over the last few months.
Armed Forces Minister James Heappey MP said the move indicates the UK’s ongoing commitment to NATO and “air policing operations.”
Two Russian Su-27 Flanker B fighter jets were spotted with a 11-20 COOT A intelligence, surveillance and reconnaissance plane near Lithuania.
On Tuesday a similar incident took place over the Baltic.
The RAF said, “This mission was more complex, as there were more aircraft to manage of different types and flying at different speeds.
“We are always ready to react in support of the NATO mission.”
Air Vice Marshal Ian Duguid, The Air Officer Commanding 11 Group said on Friday, “Today saw the second RAF intercept of Russian aircraft over the Baltic.
“This remains routine activity, however it must be stressed that the RAF as part of NATO are conducting these activities to ensure that all flights are conducted within internationally accepted aviation rules.
“When this does not happen NATO will intercept and investigate.”
Duguid added,“I congratulate all of our deployed personnel in Lithuania for the professional way that they are conducting the mission in conjunction with our Lithuanian and Spanish Allies, they bring great credit to the service.”
