A Royal Navy warship has tracked a Russian frigate off the coast of France and monitored her movement through the English Channel.
HMS Argyll, a Type 23 frigate fitted with advanced Artisan radar, used her Lynx helicopter and sensors to locate and monitor the movement of the Russian warship as she returned from a Mediterranean deployment.
Under the NATO agreement whereby alliance nations co-operate to monitor activity, the Royal Navy took over from French surveillance and sent the Fleet Ready Escort, a warship maintained at high-readiness for tasks in UK waters.
The Russian warship Yaroslav Mudry is a Neustrashimy class frigate and was sailing with her accompanying tanker, the Kola.
