    Try Saab composite vessels starting at MCMV 52 or a versatile MCMV 80. Appledore build in steel and also in the mud. There are a number of Sandowns at Baharain with clearance crews keeping sea lanes clear.

    • MCMV 80 looks quite good. But I am not sure that the NS can afford dedicated MCMVs. And at 15 knots it is very slow.

      I would look for OPVs that are built from nonmagnetic steel, which is a technology that Germany for instance mastered in the 50s, and make sure they can be equipped for a MCMV role.

        Autonomous Underwater Vehicles (AUV) including Remote Mine Demolition Craft and manned small MCM/Dive/Survey craft deployed off a ‘mother ship’ vessel are the way to go these days and for a small Naval Force who may want this capability. The beauty is the capability can be a based from an OPV or small MRV type platform. It is far more effective than traditional MCMV’s and significantly cheaper. Specialist frontline MCMV’s these days are tailored for the sharp end of a littoral warfare scenario and utilized by the big fleet Navies who can afford and have a requirement as part of their ConOps. So unless Ireland wants to be in the business of being a pathclearer for USN, NATO or RN amphibious taskforces then it is probably overkill for Ireland maritime domain.

        Much of the specialist Littoral Warfare (MMCM & Diver Support) kit can go on the ship in TEU's along with small specialist craft – operationally deployed by deck crane or stern slipway. Likewise survey gear. This kind of capability is better being accommodated off a future EPV/MRV vessel in Ireland context than having a CPV sized specialist MCM vessel. The beauty of a larger EPV/MRV vessel is that it can do patrol.

        Incidently, MCMV’s are not exactly speed merchants. Besides a powerful Radar/ISR suite with a deployed RPAS such as a Camcopter S.100 on such a vessel if EEZ patrolling was also to be tasked, can offset speed deficiencies.

          Absolutely but you won't find many CPV sized vessels with the capability to take 2 TEUs, let alone the 3 the NSDS requires

          • Not sure about the Accomodiation standards or seakeeping capabilities off Ireland's West coast, also very expensive and quite possibly over kill and over spec but .....

              Given that they aren't being produced anymore I could imagine the cost of trying to build 2 of them...

                With the order of P64 I think we're halfway there already..

                  Along with trying to sell the idea of impellers to the NS as opposed to propellers!

                    No doubt someone with more info on the inservice performance of the P50s could answer that. Outta my depth on that one I'm afraid

                    • That is why CPV/IPV sized vessels are falling out of favour with smaller Navies these days. At least a modern OPV has a Flex Deck, Crane and often a stern slipway for deploying minor craft.

                          Too large for the role & nearly as thirsty as the P40.

                          Something with shallower draught is required.
