The HMS Queen Elizabeth aircraft carrier was spotted this morning sailing past Cumbrae.
The vessel departed Portsmouth earlier this month following preperations for her next deployment.
A Royal Navy said: "HMS Queen Elizabeth has left Portsmouth Naval Base and is now at sea conducting routine exercises."
The vessel was previously in the area back in February, when she visited Glenmallen to reload armaments and refuel.
Her visit comes on the back of a major military exercise in the North Sea, which saw vessels from multiple countries manoeuvre in the area.
