The Norwegians have been able to compare operating costs directly with Danish MH-60R (Naval) and Swedish UH-60M (Land) with the UH-60 slightly cheaper obviously which are about a 1/4 of the Norwegian NH-90 cost , the Swedish NH-90 (Land version) is quoted as "significantly" more than the UH-60M but can't find a figure.
Have not heard anything good about NH-90 with Unserviceability's , maintenance and spares costing all blowing out.
Australia has 47 MRH-90 land versions, with a few aircraft parked up in hangars as tail pylons , MGB's etc all having to be sent back to Europe for repair/overhaul. Lucky to make 50% serv rate. And that's almost 10 years after the first one was introduced. 30 year old Black Hawks have a better serviceability rate at the end of their service life than the "new" MRH-90.
