HMS Lancaster has returned to Portsmouth after weeks working in the challenging waters of the Arctic.
The Type 23 frigate gained valuable experience in operating in sub-zero temperatures and also worked with Norwegian allies during her deployment.
In the Arctic, HMS Lancaster performed a night-time replenishment at sea, where stores and fuel were loaded from another ship.
The ship was also lucky to see an Orca pod while in the High North.
More recently, HMS Lancaster was one of several Royal Navy vessels to escort and monitor Russian naval traffic.
She closely tracked the Steregushchiy-class corvette Boikiy in the English Channel, using her Wildcat helicopter to gather intelligence.
