But practically all MCMV designs are about 2/3rd the size and have a max speed of 60% of the Peacocks. While also have less than 50% of the firepower.
Stick it on the back of a modified Offshore Support vessel design or vessel of similar profile. Purpose built MCMVs are very expensive for their size. Given that mine warfare will only ever be a secondary task, it is not good economy. But you can still get a DP equipped ship, with a bit of bollard pull, and shallow enough to work in the confined waters where the peacocks once went.
Interesting concept though. It makes absolute sense given the main sea lanes pass to the north and south of us, and have often been identified as a potential target for international terrorism.
The leaders in this field are still the Tripartites. Belgium France and Netherlands are still regularly disposing of WW1 and WW2 sea mines. Still lethal, still capable of closing a port for an expensively long time. They are the ones with the most up to date experience of live mine warfare. As an aside, this type of vessel also offers an ideal platform for hydrographic survey, as was seen in Iraq after the ousting of Saddam. The RN took some minesweepers in and cleared the port of Umm Qasr of sunken warships.For now, everything hangs on implementation of the CoDF report.

And the russians have a long history of using mines in the baltic, it allows us to contribute.

But the WP say "similar vessels" ie probably <1000 tonnes displacement

The three new River Class OPV's are 90m, and the contract for them is costing the Brits £348 million (I would assume that includes a maintenance contract too). A pricey replacement, plus about a thousand tonnes more than what is suggested in the White Paper.What are you cackling at, fatty? Too much pie, that's your problem.

That sort of thinking would get you a long way in the DoD.

Given the crewing commitment , cost of operation etc, might as well be an 90m OPV bought in for replacement.
We bought sweepers to replace corvettes, which were essentially OPVs, sweepers were handy in shore because of the twin screw capacity that PVs didn't have and sweepers were limited in off shore capacity so the CPV requirement was actually a myth with the Peacocks being bought to replace the sweepers which were never intended to be purchased with a specific inshore capacity,
OPV could deploy its RHIBs to do the same job!!
The days of the 'Salmon Patrols' and the ensuing actions are long gone..OPVs all the way...Covid 19 is not over ....it's still very real..Hand Hygiene, Social Distancing and Masks.. keep safe

CPV arrested a vessel last week fishing for sprat within Waterford harbour. Would the OPVs be able to operate easily in these confined waters?
Two fishing vessels detained in Waterford
Two fishing vessels were detained by the Irish Naval Service and escorted into Dunmore East this morning.
It is alleged they were fishing for sprat without authorisation.
The two vessels were observed fishing in Waterford Harbour by the Fisheries Monitoring Centre.
The LE Ciara which was in the area was sent to investigate and boarded the trawlers.
Both were detained at around 10.30am after allegedly fishing for sprat.
Fishing for herring and sprat is prohibited on the South East Coast from September 20 to December 31.
The trawlers were escorted to Dunmore East and handed over to gardaí, which is normal procedure.
A spokesperson for the Irish Naval Service said: "During the boarding and inspection of the two vessels a minor confrontation occurred between the two fishing vessels and a number of local boats.
"It is alleged by one of the detained boats that his nets have been damaged," adding that "this is a civil law matter".For now, everything hangs on implementation of the CoDF report.

They also recieved money for the cost of arguably meaningless "redesigns" (possibly the actual cost of the OPVs) including a "Merlin capable" helipad (no hangar).
They are intended to replace not augument the current three Rivers which will probably be sold.(they might be good buys for NS if they come to market) Anyone who imagines that these OPVs will be patrolling the North Atlantic in winter with a Merlin strapped on their backs needs their head examined.Last edited by Galloglass; 17 October 2015, 13:35.
