The Navy’s New Patrol Boat

US_Navy_MK_VI_Patrol_Boat_Sea_Air_Space_2015_1

The Navy has placed orders for five Patrol Boats of a new type, with up to 48 planned. Announcements here and here. At 85 ft long, it is a size the Coast Guard is familiar with, and it is made by Safe Boats International LLC, a company the Coast Guard contracted to build its own Response Boat-Small, Special Purpose Craft-Law Enforcement (SPC-LE), and Special Purpose Craft-Near Shore Life Boat (SPC-NLB). In fact the new patrol boat is a development of the same family as the Special Purpose Craft-Near Shore Life Boat (SPC-NLB) which suggest it may even be self-righting.

Step-down cut-outs on the hull, similar to those on 47 foot motor lifeboats, are visible in the illustration, making it easier to board smaller vessels or pull people from the water. Sprint speed is up to 41 knots with 35 sustained. Accommodations appear crowded and relatively austere compared to Coast Guard patrol boats.

Interestingly the boats are being bought through GSA. At approximately $6M the price is not bad.

The Center for International Maritime Security has some interesting discussion about how they might be used. Below is an illustration from that post, originally provided by Navy Undersecretary Bob Work at a CATO Institute event,  showing how the boats might be transported in the well decks of various classes of amphibious warfare ships.

Mk VI Well Deck

Lee Wahler, who writes for www.warboats.org and is a frequent contributor here, believes the boat grew out of this Request For Information, from 12 Nov 09. (Thanks Lee) This may provide some additional insight into the rationale behind the design:

43 thoughts on “The Navy’s New Patrol Boat

  1. The USN seems to have forgotten that boats were launched by davit and crane LONG before wet well docks came into existence. Depending on the boat, davits are quicker to launch multiple boats. In addition, I don’t think there will be enough amphib warships available to go to many possible patrol locations? OR said differently, so long as the USN ties NECC units to amphibs then the increased capability is limited by hulls available. Solution: Use other ship types to conduct soft power missions. Thus allowing amphibs to got where they might be really needed, and decreasing the “footprint” near foreign shores.

    I mean if you were a small country would you want a ARG sitting offshore just to say take care of some pirates? OR would it be better to support the Mk VIs inport?

    And since MPF are mentioned, I would note that USN boats HAVE been lifted on MPS before.

    • I did notice in the RFI you provided they talked about other ways to transport the boat, including lifting by crane, and air and road transportation:

      “Transportability: Maritime: Capable of being transported and logistical launch and recovery via a well deck, crane or deck cargo transport aboard USN and/or MSC/common US/coalition commercial ships. (Consideration of tie downs and amphibious operations kick stand). Hoisting: Lifting eyes for single point lift to allow launch/recovery or loading/unloading with at sea and/or shore side cranes as required in transport above. (Individual leg soft slings, and man portable hardware is preferred). Terrestrial: Desired improved road / highway transport objective for Medium Tactical Vehicle Replacement (MTVR) tractor variant prime mover with an organic trailer with special permit and wide load transport restrictions. Not to be considered a constraining requirement. Air: Desired internal air in C-17 and/or C-5 transport on a trailer. The prime mover does not need to travel in the same aircraft. Not to be considered a constraining requirement.”

  2. These are not patrol boats, by CG terms this is just a big small boat. Sounds like they really want a hybrid boat that can escort subs far offshore like the MFPU 87’s do now but also a screening vessel like the CG 64’s bristling with guns, and a boat shallow enough for riverine ops. Looks like a good hybrid work horse for the Navy’s littoral dreams that can also do escorts. RE other options than the well deck, Navy ships already use cranes to lower CG CB-OTH’s (when they can get their hands on some), what surprises me is that they didn’t envision this as an option with the LCS’s. Given the massive internal bay of the LCS-1 style ships, along with the overhead gantry, it wouldn’t have been too much of a stretch. It seems a shame, can’t really retrofit that very easily.

    Anyways, this tool makes a lot more sense to launch from a well for VBSS and port security than the LCU’s and LCAC’s. Not surprised they are building these. They ask for this type of capability often from the CG, but there aren’t enough to go around.

    • drc, at 85 ft they do exceed the USCG cut for patrol “boats” but not the Navy’s~ the navy wanted an offshore security boat (hence earlier designation). I thought of the navy bought 64 ft port security boat like used in Kings Bay. I also thought of the USMI Mk V PB-Composite and also looked at Swiftships 83 ft PB.

      NO the Navy was not looking hybrid just merged two boat rqmts into one (like they did with Cyclones, and look what it got them?~). The Navy i.e. PMS325G likes to buy off the GSA sked with better or worse results.

      Go look atythe cranes on modern warships or lack of same. Damn few can handle anything larger than an 11 meter RIB. LCS handle those boats internally. And apparently the Navy saw NO need to have any larger boat inside? JHSV has a crane and space to handle up to 40k 12 meter boat. You do realize the TIME in takes to ballast down and launch ANY boat out of a wet well don’t you?

      My conclusion is cranes and davits are faster and better depending on boat size.

    • Desk Riding Cutterman, I get the same feel. The Coast Guard only uses the “Special Purpose Craft-Near Shore Life Boat” (SPC-NLB), from the same family of boats, in the unique circumstances of a harbor with a shallow bar. Choice of shallow draft and high speed probably means these boats will be hard riding. If the RFI concepts still apply, there is no intention to keep the boat underway for more than 24 hours at a time. Reference to MREs rather than on board cooking facilities, shock mitigating seats, and only two watch sections all suggest these boats will not “patrol;” they will go out for specific missions and return as soon as it is over.

      Still, it seems likely some of the VSBB teams riding these will end up being Coast Guard.

  3. Memory fades at times, but did not the Coast Guard try out an 85-footish Safe Boat some years ago?

    In the carry plans, where are the LCACs going to fit. How are the Marines going to get their stuff moved around.

    • The article accurately describes the CG response to the earmark. The boat was tested and we confirmed it didn’t meet the requirements for CG missions.

  4. Maybe the US Navy is trying the proven concept that the Dutch Navy is using to Fight Piracy such as using a frigate or a destroyer as a command center and having a LPD act as a mother ship for a small fleet of CB-90’s or MK VI. With that concept that can support special ops teams as well.

  5. IMHO the Navy is doing NOTHING MORE than expanding the force protection envelop offshore to include a) protection of its Gators, b) VBSS further offshore than now, and c) finally only IF it happens within a tightly defined area – anti-piracy ops. The emphasis is on Defense of the fleet (not necessarily our merchant fleet~).

    The Mk VI may have a nice weapons suite (IF built like the drawings) but pretty obviously can not operate ScanEagle UAV. There is NO singular advance in systems. IOW the Mk VI is a big patrol boat NOT a FAC. Not a gunboat, not a weapons platform, nothing new or special.

    Nicky this is an NECC boat period. The NSW sailors are wanting something different might I say better?

  7. NavyRecognition has a video including interviews from the Navy League’s 2014 Sea-Air-Space Exposition that touches on a number of systems we have talked about here. I am going to post this same comment on each of the threads I think are related. The video can be found here:

    [youtube http://www.youtube.com/watch?v=9-9mCsNe-zc&w=560&h=315%5D

    At minute 9:00 there is a discussion of the Brimstone missile.
    At minute 13:00 we see a model of Eastern’s proposal for the Offshore Patrol Cutter. Unfortunately, there is no accompanying comments.
    At 13:15 we get an about one minute of update on the Navy’s new 85 foot MKVI patrol boat
    About minute 15:03 they talk about a new hyper-velocity round being developed to be fired from the 5″ (and other) gun.
    About 18:35 they talk about HII’s proposal for a frigate developed from the National Security Cutter, but it doesn’t look like any new info.

  8. I’ve seen one of these operating on Puget Sound in the Seattle area. Don’t know if it is builder’s trials but it would be a short run from Safe Boat’s Port Orchard facility.

  9. ‘The Force Protection – Coastal (FP-C) Craft” A confused cross between the Vietnam era PCF and PT. Just because a boat can run fast and be bristling with guns does not make it a patrol boat. Patrol boats are, by nature, best at slow speeds and vigilance – not fire power. This boat would be nothing more than a large target on riverine operations. I do not recall reading about this boats habitability. Perhaps the Navy should go back and take a look at the parameters it used in 1964 for a suitable patrol boat. Of course, they did not get one then either.

    • As best I can tell they don’t expect this boat to go out for more than 24 hours. Galley appears minimal. As you say, it is apparently built more for speed than for “seakindliness” so hard riding in most conditions.
