Royal Navy Offshore Patrol Vessels HMS Spey and HMS Tamar set sail from Portsmouth on Tuesday to begin their deployment to the Indo-Pacific region.
Acting as the eyes and ears of the Royal Navy, they will be deployed from the east of Africa to the west coast of the USA during the next five years.
No permanent home has been assigned to the pair - instead they will use Pacific bases and ports which best meet their needs and mission.
Both ships, with their historic dazzle camouflage paint scheme, will now head to Falmouth, Cornwall, before leaving the UK later this week.
