| Source measurement | — | These small (53 m; 174 ft) fibreglass vessels are single role mine hunters (SRMH) rather than minesweepers. Twelve ships were built for the Royal Navy and three ships were exported to Saudi Arabia . Three Royal Navy vessels were decommissioned following the Strategic Defence Review in 2003; Sandown (January 2005), Inverness (April 2005) and Bridport (July 2004). A further ship, Cromer , was decommissioned and transferred to a training role at the Britannia Royal Naval College in Dartmouth in 2001 as Hindostan .[source]Sandown-class minehunter · Development; only the objects and conditions stated in this passage |
