Also, here is a link to a video showing Stiletto launching an Aerosonde Mark 4.7 UAV. Very interesting which I couldn’t embed for some reason.

    while I can’t give my source, you can read some comments on Warboats.org Forum

    Leesea,
    My thought too…and then I watched to the very end…and they show personnel being recovered on the RHIB (but the M80 seems to not be moving).

    Interesting note about the SWCC rejection…

    Soloman FYI on Stilletto background. At one point in time the SOCOM boat folks had an RFI out for a ship which could transport a platoon plus of SEALS at high speed and debark them in AO. The M Ship company with some congressional help submitted the M80 Stiletto. The boat was tested and rejected by SWCCs (our Navy’s professional warboat drivers).

    While touted as transformational there is not much other than the electronics which is new and the minimal weapons makes it more of a boston whaler than a proven CB-90.

    Then M-Ship shopped their boat around and got a few R&D type tests and a couple of short term missions (not from the Navy).

    All the rest about this plastic can is PR hype IMHO.

    CBD I would guess the stern recovery ramp is NOT personnel rated system?

    There is already several US versions of the CB-90 being driven by new riverines and called the Riverine Command Boat. Although I would call them the Riverine Combat Boat!

    Just a quick few comments on the video:
    – Role 1 (SOF): Is there a known safety issue with recovery of the 11m RHIB? Why else would they specify crew off-loading prior to recovery via boat ramp? As for the issue of range: that’s why they have used H-46, H-53 or the MkV PB (each of which can deploy RHIBs). The same capabilities exist in the PC series, which has a gun and a SHORAD system.

    – Role 2 (Area support): 2 onboard USVs and 4-6 RHIBs that helpfully take care of themselves. I also like that the USVs are not detected by the ‘ambush’ forces, that the USVs have no weapons system (requiring a manned crew to engage) and that manned crews in RHIBs are unable to engage without being noticed first.

    – Role 3 (MIO): How is interdiction for a large cargo ship better performed by the Stiletto than by existing craft?

    The problem of the M80 is that it offers limited improvements. I think that the networking and hull material is the big improvement. IMHO, the benefit of carbon fiber hull materials is better seen in the Hamina and Visby classes.

    I don’t get the need for the Stilletto.

    The mother ship can launch the UAVs and the CB90 which is larger than a RIB can launch from the mothership also.

    Kinda takes the middleman out of it with a more capable and cheaper ship attached to mother.

    CB90 is as fast, can transport an assault element and doesn’t beat up its passengers….

    Cheaper isn’t always less capable…dump stilletto switch to the CB90….the Netherlands does!

    I’m a fan of stern ramps properly executed but surface piercing props make them a bad idea, even with those afterthought looking guards.

    Yes. I finally got hooked back up with the folks on the Norwegian side of the project and am waiting on the results of their excavation of project files.

    I had recalled correctly that our OPV variant had a 2500 nm unrefueled range…at 30 knots. ;-)…just to tickle yr interest.

    I was also reminded in my conversations with my Norweegian counterpart that our proposed OPV variant with a 40-45 knot sprint speed had a ‘problem’..at the time there was no diesel package except for a hypothetical Paxman configuration that matched our space/power/weight requirements. That meant we were still forced to have a CODOG propulsion system in that variant unless a lower top sprint speed was acceptable. We are both going to revisit that part of the design.

    I am going to create a dedicated space on our web site for the display of the concept naval vessels that were variants of the Cirr120P (35m), Skjold (47m) and Oksoy (54m) surface effect ships.

    @ Bill : any update on the International Variant of Skjold discussed recently ?
