She is a Sandown-class Mine Counter-Measures Vessel stationed at HMNB Clyde (Faslane).
The crew of HMS Pembroke is made up of highly trained Mine Warfare Specialists and Mine Clearance Divers, as well as engineers, officers and chefs.
The vessel is 52.5 metres in length and is currently part of the NATO Mine Counter-Measures Maritime Group.
This group operates in Northern Europe and the Baltic Sea and involves mine clearance exercises and security patrols to support the UK's maritime commitment to NATO operations.
