Must I remind some people here that the US Navy themselves trough NATO asked the Belgians to take care of the mine sweeping in the street of Hormuz in the 90's as we are well known to be the best in the world in it? (and the best equipped ships for that matter). We still find WWII bombs in the North Sea and English Channel.
I seem to remember the Royal Navy doing some sweeping in the late 80's - Op Calendar / Cimmnel IIRC? It got me a couple of long weekends in Dubai whatever they were doing.
