    Sorry I meant to say plans are for a total of 58.

    There are outstanding options for 34 Sentinels and the plan is to make 54. Average price if all options are exercised is $44M per boat plus adjustments for inflation.

    DE. Thanks. I know sometimes in Forums they grab copyrighted stuff without permission. I try to be very careful myself.

    About your question regarding those photos of Somali pirates being captured by Portugese Marines… Note this line of credits for a reposting of one of those photos: (AP / CPO Carlos Dias / NATO / Ho). I believe that this means that a Portugese Navy Chief Petty Officer named Carlos Dias provided these photos through NATO. Then there is this part of the photo’s caption: “In this image made available by NATO Friday Dec. 18, 2009.” I suspect that it would be OK to use these photos on the blog. You can view the photo (with credits) in posting # 20 of the following thread.

    For anyone that thinks China isnt throwing their weight around in the south pacific look at what Vietnam has been doing in the past few years with their military. Su-30s and Kilo class subs!

    James, as you say there isn’t much left to cut. The carrier admirals must be increasingly worried but they are depending on the employment issue to see them through. The frigates need replacement, not a continued weeding of their numbers.

    The RN didn’t fare too badly in the UK Defence budget cuts, probably because there isnt much left to be cut anyway due to previous defence cuts. The RAF has suffered most, but arguably they have escaped cuts for some years now and need to focus on their support role rather than just acquiring as many fast jets as they can get hold of!

    The opinion article about ‘seablindness’ is very interesting, and I find it difficult to disagree with the points that he puts across.

    PNS Shah Jahan is the old RN Frigate HMS Active. Exactly the kind of small patrol frigates we could do with now. Although they did suffer from hull cracking.

    TLAM attacks were used to strike at two Al Qaeda targets in Yemen on Thursday. President Barack Obama ordered the missile attacks. I wonder if it was USS Chosin (CG-65), flagship of CTF-151 (which just happens to be in the neighborhood) which fired off the Tomahawks. It would be nice to have a pirate fighter go totally badass and strategic all of a sudden…

    Hi Heretic,
    Re: tumblehome and multi-hulls. The tumblehome shape, where the the maximum beam is below he deck line, in theory (if roll is great) creates problems because the rate of growth of righting moment (buoyancy of the immersisng side of the hull) decreases after the tumble home point is reached. At the same time the area coming out of the water increases on the high side so the waterplane area gets smaller and the reistance to roll is reduced. In multi- hulls the righting moment comes from the leverage of the outer hulls, (dist. between hull center lines) as they are submerged. These hulls are usually quite V shaped so the opposite to the above is effected i.e increased resistance to roll with greater immersion. The virtue of multi-hulls is that they achieve high roll stabililty (stiffness) with a small waterplane area, waterplane area is a key determinant of wave making resistance (along with length and speed). Their high performance is achieved by long slender hull forms, optimal outer hull placing usually corresponding to the run of the max beam of center hull (located aft). When you look at photos of LCS Independence you will notice very little bow wave,this is due to the very long slender hull form forward of the outer hulls. This has additional benefits in that there is minimum disturbance around the forward sensors (sonars) i.e she will be very quiet upfront. The tri-hull form of Independence was inspired by Indonesian outriggers, (they have many different names and versions) thought Austal refers to them Amahs, these craft have been found drifting or beached in Australian waters uncapsized after thousands of miles at sea, testimony to the stability! These characteristics scale up very well hence the evolution of the shape into large high performance (high speed, high stability) vessels.

    Since the photos were likely made available via a press release of NATO, EU Atalanta, or the Portugese Navy, then they may be in the public domain. Most of what appears at do seem to items made available via press releases from the forces involved. I just don’t know what to tell you regarding the use of imagery posted to that site, except that they do seem to be made freely available.

    Dutch release their pirates as reported in the links above. The boys will be home for Christmas:

    Suspected Somalia pirates freed by Dutch navy.

    Also, on the Predator Hacking story, the leadership thinks it isn’t much of one according to Stephen Trimble:

    “”We’re talking about interception of signals that are broadcast over the air – duh,” Deptula says.”

    D.E. Excellent photos! Wonder what the rules are there about using photos on other websites and blogs? Found nothing in their FAQs on the subject. I would like to repost some.

    Do you think there are both real pirates off the Horn and a lot of wannabes too?

    Some interesting pictures of Portugese Marines taking down Somali pirates can be found at the following link. Six pirates were captured by the Portugese frigate NRP Alvares Cabral earlier today. Note that an aerial shot of a pirate skiff shows one boat and then surface shots show a different boat (one skiff is festooned with brown Xs painted across it, while the other is plain white & carries a ladder – unless the Marines were marking the boat with the Xs after a capture & release). Then, in a photo with the Marines aboard the skiff you see six pirates huddled (terrified) in the bow of the skiff. Only, there’s a seventh pirate in the water whose head is barely visible below the skiff’s gunwhale (lower left corner). One could wonder what might have been happening. Perhaps one of the six slipped overboard?

    Just scroll down to posting # 21 and there are nine photos in the middle of the posting. Two of the nine photos are duplicates.

    Wow, I don’t think I’ve ever seen a set of stats as misleading and just plain wrong as what that website (and DebkaFile) has for the Protector USV.

    The gun station is a miniTyphoon (mounts .50cal, 40mm GMG or Mk 48 medium machine gun), directed by onboard electro-optics. Range is maybe 1/2 mile with the Mk 48 and a little over a mile with the M2. Detection ranges and abilities described are laughable for a craft about 3m tall. Oh, and likely no cruise missile interception capability.

    I have an … odd question … which I have no way to answer (or even speculate about an answer), in part because it requires a knowledge of shipbuilding and sea dynamics that I most certainly don’t have.

    Tumblehome Hullform.
    Trimaran or Catamaran layout.

    What happens to a ship’s design when you combine the Tumblehome form with a Trimaran arrangement of hulls to form a single, unified seakeeping vessel? I ask this because one of the (major?) concerns about the Tumblehome hullform is that while it’s great for RCS reduction (among other things), it may have issues with rolling moments. However, a Trimaran would (presumably) greatly mitigate/reduce those concerns since the outrigger hulls would go a very long way towards positively preventing the ship from rolling over in heavy seas.

    Does anyone here on this blog have the necessary shipbuilding background/experience to answer this sort of question beyond the layman’s eyeball guess of “I suppose so …”

    Reason I ask is because it *feels* as though there might be some untapped potential/synergies to be found in such a radical departure from mono-hulled ship building for for surface combatants …

    The USN T-AGOS ships are also very capable and essential.

  20. December 18, 2009 9:22 am

    People are often amazed when I explain the importance of the hydrographic service.

    When the word survey ship was used early on I was expecting it to be the Plum.

    The RN still has a very capable squadron with Scott, Enterprise, and Echo.
