A Russian Tupolew Tu-142 reconnaissance aircraft repeatedly approached a British carrier strike group in the Norwegian Sea on July 2.
The Russian crew dropped several sonar buoys near the HMS Prince of Wales and reportedly ignored international safety radio frequencies.
Two British F-35 fighter jets were deployed to intercept the Russian jet and escort it away from the naval formation.
The incident occurred during the Nato-led Operation Firecrest, a mission aimed at enhancing security and presence in the High North.
