Fishery Patrol Squadron Purchased – the Royal Navy has ended a decade long lease deal which was costing £7m a year, and has bought outright the three Fishery Protection Ships, TYNE, SEVERN and MERSEY.    The ships entered service in 2003, initially under a five year lease to the Royal Navy, and subsequently renewed, and was due to be renewed again in 2013.     The trio – nicknamed the ‘Cod Squad’ – are based in Portsmouth, but are rarely seen in their home port as they range around UK waters protecting fishing stocks, working alongside colleagues in the Marine Management Organisation.
