Question to the Ministry of Defence:
To ask Her Majesty's Government how many River-class minesweepers, if any, remain in service with the Royal Navy or the Royal Naval Reserve.
No River Class Minesweepers remain in service with the Royal Navy (RN) or the Royal Naval Reserve (RNR).
Twelve River Class Minesweepers were built in the 1980s. Eleven were assigned to the RNR units around the UK, and a twelfth ship was operated by the RN's Fishery Protection Squadron. All 12 ships were decommissioned and sold during the 1990s.
Today, the RN operates a fleet of 13 Mine Counter Measure Vessels (six Hunt Class and seven Sandown Class).
