HMS Itchen (M2009): Patrolling Northern Ireland's Waterways During the Troubles

Built by Richards
HMS Itchen was built by Richards Shipbuilders at their Lowestoft and Great Yarmouth yards, one of twelve River-class minesweepers constructed for the Royal Navy, a class designed with a deliberate dual purpose in mind: genuinely capable minehunting and minesweeping vessels that also served as effective training platforms for the part-time sailors of the Royal Naval Reserve.
A Different Kind of Patrol
HMS Itchen was subsequently assigned to the Northern Ireland Squadron, a posting that took her a long way from conventional minesweeping duty: she replaced older Ton-class vessels in patrolling the province's inland waterways and lough systems during a period of sustained political violence, and took part in counter-terrorist operations, unglamorous but genuinely dangerous work that saw small naval vessels playing a direct role in supporting the wider security effort in Northern Ireland during the Troubles, a role considerably removed from the more conventional minehunting and reservist training duties most of her sister ships were built for.
Sold to Brazil
HMS Itchen was decommissioned as part of a wave of Royal Navy ship disposals between 1997 and 2003, and was subsequently sold to Brazil, joining several of her River-class sister ships in finding a second working life with an overseas navy once her British service came to an end, a fairly typical fate for a class of sturdy, well built minesweepers whose usefulness clearly outlasted their time with the Royal Navy itself.
