    Swerve fair point i’ve only seen speculation of CAMM being able to travel upto 30km and i’ve seen it as >25km on the web semi-official im thinking maybe 27-28km realistically.

    The ESSM uses the self defense variant of the Mk41 launcher which is 5.6 metres externally wheras the Aster 15 uses the A43 launcher which is 4.3 metres internally so they are much closer in length than you might think. So im not to sure how close in size they would actually be but i think it would be close enough that it would be a design problem.

    The Mk41 does weigh more but that is down to the fact that the Sylver launcher uses supposedly more advanced materials such as composites etc to lower weight. In my opinion weight is not a huge issue as it is mounted low in the hull furthermore most of the hulls we would put a missile capability on are large enough for this to be a non-issue. The Quad Packed ESSM would be heavier than a single Aster 15 there is no doubt in that as there would be less air in the cell and more missile.

    There is also the outside option to integrate the Sylver launcher and ESSM missile therefore the launcher would not be an issue and it would be a simpler choice, i say this as the ESSM missile is roughly 3.66 metres long according to what a quick google shows so it would fit into the A43 launcher. Maybe integration would be a help in the export market as it would make the Sylver launcher more attractive to other nations i can’t see who though it would help ESSM sales as well as you could have a French ship design with a French sensor suite with a US missile but with the capability to use French missiles should ITAR spoil the fun.

    Basically your point is correct, but i think that it is not a huge issue and would not present many problems in terms of design for the weight etc. I wonder how much money could be saved by ditching CAMM and just buying ESSM over the long term and having all the R&D as well as support in place.

    A few Notes Missile ranges have to be taken with a huge pinch of salt many ranges are worked out in a straight line in certain conditions. In reality of course we know that missiles dont fly straight lines nor is the environment the same as in a lab or on a test day weather can affect how the missile performs. Many system manufacturers say it’ll do this that and the other but if you know people in the services they will tell you otherwise, some systems they describe in expletives and others with admiration.

    Something like ESSM is not an Area weapon they are in my mind a SHORAD weapon basically something pop’s up on your horizon and ESSM has enough range to go get it as soon as it appears, basically local area. Things like Sea Wolf only get it when you can basically see the f**cker bearing down on you and for that Job a proper CIWS is better in my opinion. CAMM is a half-ars£d version it sits in the middile of point defence and local area defence the main reason it has the 30km range is i think to do with it’s ASRAAM heritage. ASRAAM has a range of around 18-20km and CAMM is quoted as 25-30km so with advances in motor technology and a slightly longer body then the longer range is attainable.

    I personally like the US missile options a bit better, the standard missile allows you to engage the platform that is carrying a weapon such as a missile, ESSM then allows you to engage any missile as soon as it appears on your horizon and finally Phalanx or RIM-116 (Rolling Airframe Missile) provides your last ditch attempt. That is a proper layered air defense in my opinion giving the maximum likelyhood of a successful kill. The future RN outlook is in my opinion not as great, Aster 30 the longest range missile has a range of 120km whereas the SM-2 block 4 has a range of 240km so the SM-2 can hit the launch platform when it is further away out of firing range for things like Exocet or Harpoon. The mid tier options for us are Aster 15 or soon to be CAMM each with around a 30km range whereas the US and other allies have the 50km ESSM allowing engagement of a target as soon as it appears on the horizon. You might be thinking ah but the Aster 15 and CAMM can reach the horizon but what i mean is that ESSM will without question have the range with fuel to maneuver whereas Aster and CAMM will maybe not. An additional point Aster 15 cannot be quad-packed and CAMM can so only CAMM is really in the same group as ESSM. Finally at the point defence side of things the US has the Phalanx and RIM-116 we have phalanx and Sea Wolf at present and from what i’ve heard people like Phalanx more.

    A cheeky point is the USN also has proper AEW and carriers so the launch platform will likely be dead in most cases as soon as it is detected hundreds of miles away, or the place where it was based would have been destroyed simple really. This means the USN in reality has very little chance of being fired upon in most cases as the threat would already be dead outwith missile range. In contrast the RN is maybe going to get 2 carriers without AEW and without proper fighters and ancillary aircraft so much more pressure will be put on the almost non-existent T45 fleet, sounds like a bad idea to me.

    Basically all in i like the US systems better, im not saying buy them outright but i dont think what we will be getting is quite as comprehensive as what has been in US service for a while. There is the option of Active ESSM which is/may get developed and SM-6 will also have an Active seeker so that will make the retrofit possible if some mad person decided to dump Aster. Yeah i know that means dumping home grown systems but Aster is mainly french and CAMM might turn out to be just another European system that not many people buy.

    Now for the “it won’t happen so it’s not worth the hassle” routine, i would rather have a proper solid AAW capability for the RN rather than some Euro jobs program.

    It was a very rough calculation, and I didn’t know that radar could see through the earth.

    Erm! propagation of radio waves and all that physics stuff, i dont wanna get my physics books out im not great at it.

    Minor question, and slightly O/T. The cover on the Goalkeeper, I assume it would be removed if a ship went to GQ? However if the ship were attacked by without warning how would the cover be removed, could the gun just shoot through the cover, or would the initial round remove it or is the system U/S until the cover is removed by hand?

    The cover is fibreglass IIRC so yeah you could shoot it through but im pretty sure they will have a decent idea of when they might get attacked and from who. Ships dont generally get attacked out of the blue with someone packing AShM’s.

    Indeed. BTW, the active radar seeker used on Mica is very closely related to that on Aster.

    Very true indeed, makes sense as it should have saved some cash and developments from Mica or Aster can be shared.

    In regards to a shorter ranged Aster i think if you took the booster away it would have a tiny range as Aster 15 is only 30km’s so removing the booster would drop it right down into CIWS range. I personally think there is a massive abundance of Naval Systems in Europe thanks to all the differing navies and nationalistic pride in developing new systems. If i was given the choice i would have went with the NATO Evolved Sea Sparrow Missile as it is a proven system in-use worldwide and with a better range than proposed CAMM and cheaper to boot. The problem is it’s semi active but there is/was an Active version mooted so that could work.

    Basically with some work Mica could be Quad-packed, how hard is it to make the fins fold is it a difficult job? The fins on ESSM fold i think but im not sure about that i dont know very much about it if im honest just done a quick google.

    For anyone that’s intrested there is a pic and a page of Text in Warship Technology
    http://content.yudu.com/A1gka6/WTOCT09/resources/index.htm?referrerUrl=http%3A%2F%2Fwww.rina.org.uk%2Fwt.html if it’s not on the correct page then goto page 6.

    Are you suprised it’s not a British ship, i live on the clyde and if you watch the ships go by few are British owned or flagged, hell if you look at the Shipping AIS system there are far far far more foreign ships. Just the way that the maritime industry in the UK has been attacked and neglected by Government, Sea Blindness is a dangerous thing and one day it will come back to bite us in the backside.

    Btw, F-35 if you can get pics post them if you can:) we would be most thankfull.

    Aye ok it will be quad packed when it is deployed if it is integrated with Sylver launchers which i hope it will. MBDA seem to have 2 options for their own launchers one is a small tube with the gas system at the bottom for a soft vertical launch and the other is like that picture a quad packed single tube design with soft launch.

    The points on VL Mica i agree with as im coming up with similar evidence online so no quibbles there. Random Q, Do you read Warship technology Swerve?

    Pj we all know CAMM is Quad-packed that is not in Question, nice pic from the MBDA site though.

    What people are discussing is if the VL Mica can be quad packed atm, in my opinion the answer is not currently. However it should be quad-packable as it is not a huge missile therefore it just needs someone to order it quadpacked in a launcher, the Greek FREMM drawings and specs out there show 24 A35 cells each with a single missile so that is where im drawing my answer from.

    Furthermore the DCNS Sylver PDF shows only one missile per cell> http://www.dcnsgroup.com/files/pdf/Sylver.pdf it’s on page 2 btw. Im sure there was some information somewhere on the great interweb about the exact dimensions of each cell that i read. If anyone knows the exact dimension’s please post.

    EDIT: After trawling through some crap what i’ve found is each cell is 22 inches or 55.88 cm square, seems a bit small but that’s from The Naval Institute guide to world naval weapon systems.

    To be honest the reason why i dont think it can be quad-packed is because the Greek FREMM’s are said to carry 24 VL Mica and the launchers for them are beside the hangar so 24 missiles 24 cells. I could be wrong as i dont have much to go on really apart from some sketchy info.

    Swerve very good point the diameter will not include the fins for the Mica missiles and no they dont fold and im pretty sure of it, well the land based VL Mica certainly doesn’t and thats the same as the naval one.

    I MOST CERTAINLY think the carriers should be built! My point was scheduling, FSC is the next intended project. If the carriers are cancelled there is nothing else in the books to keep the yards active until FSC…they would have to close through lack of work!

    Thank beep for that, i was unsure of your meaning there, i also think the carriers should be built so i agree on that. I’ve already commented about my shipbuilding ideas elsewhere but i think generally a strategy needs to be drawn up one that includes all the ships we will definitely order. The MoD signed a 15 year commitment at some point this year so that should be the basis for a long term build program, in other words place firm orders for the full classes of ships. If a Government decides on this now they can have the schedule drawn up and all the details worked out with industry and then include penalty clauses for both the Government and Industry.

    You have opened my eyes to a concept I hadn’t considered that BAE Systems might enjoy getting out of the ship building business…no longer having to keep open expensive yards and concentrate on systems that can be fitted onto ships built in foreign yards. A very sad idea but I can see the corporate thinking!!!

    It is sad corporate thinking that get’s me to that conclusion, in shipbuilding margins are not that big and you need a stream of work to keep a yard viable. Coupled with the Sea Blindness in the UK as a whole and dithering by Government it’s not a safe steady industry. Simply put BAE can make more money from Systems hence the re-branding of the company, also other companies have done this before them and it has proven fruitful notably VT. BAE have also hinted that they want to be a systems only company and the only thing stopping them seems to be the UK government paying them not to.

    What would happen to the shipyards i have no idea, the only one that is truely important is Barrow that builds submarines as you cannot buy SSN’s on the open market. The other yards Govan etc i feel would not be commercially attractive to anyone as they are very old yards hemmed in by the City of Glasgow. Modern shipbuilding is done in huge drydocks and blocks made in sprawling workshops, Govan etc simply do not have these facilities and could not be easily added.

    Basically my understanding is that AESA radars are like big antennas and you can do lot’s of cool stuff with them, from the simple im a radar to high power focused RF beams (Death ray kinda thing, what radar was meant to be originally). One huge and apparently simple use of AESA technology in future will be ultra high bandwidth data links these would be somewhat of a game changer when you can move vast amounts of data between platforms.

    On another note I do feel UK shipyards and suppliers are in a race now through to the next election to get as much work done on Queen Elizabeth to make any cancellation utterly perverse and foolish! Whilst I will welcome a change of government (a very hard thing for a Lib Dem to say about a coming Tory government) but some worrying statements have come out of them recently in respect of defence and the current crop of Tories have a known army bias. What frustrates me is with all these talk of cuts in programs from ALL parties is the lack of understanding of the concept of MONEY already spent and KNOCK ON!

    One thing i think we can all agree on is that every political party has a definite Sea Blindness but also even worse a blindness to the Armed Forces as a whole. The problem however does not just lie with the politicians but the electorate as a whole, why we see things diffrently only we know. In my opinion the first role of a Government is to protect the people and the nation as a whole.

    In regards to the Carrier that’s what i feel they should do as well is get as much work done as fast as possible and try and save some money through efficiency. The idea is to make the carriers a serious problem if they were cancelled and also to make them more attractive to be kept by pushing down the price and getting work done. The problem is this will never happen BAE is too selfish and narrow minded to do anything in my mind, i think they would rather get out of the shipbuilding game as they would rather be a defence systems company.

    For example cancel the carriers and forget getting FSC from a British yard.

    What are you saying here? are you saying you think the Carriers should be cancelled? If they are and we don’t build the FSC in our yards what will they do, sit there and die?

    Stan, Nice to see you found the good old Jumper missile, something like this would be handy for situations where you need limited land attack and fast, you put lots of these on a Herky bird and fly them to a port and get them fitted to a C3. I wonder if it could also attack ships with the laser guidance unit, i dont see why not.

    I don’t see the overlap with Aster 15 as being a problem, if it replaces Aster 15. You get three extra missiles, or the same number of self-defence missiles in a quarter the number of cells , leaving more free for Aster 30. This could make the Sylver/Aster 30 combination more attractive to anyone looking at missile count, & comparing it with Mk 41/Standard/ESSM. Think about it: if someone offered you, the captain of a ship, 40 long-range & 32 short-range missiles, or 40 & 8, which would you prefer? If the 32 perform, of course.

    I personally hope it does replace Aster 15 as i have some opinions on it, notably it’s the same dart as the Aster 30 is only roughly 70cm shorter and has a quarter of the range. I would definitely want the mixed missile load out as it means i could use the longer range missile to attack any launch platforms and have enough short range missiles to try and take down the actual missiles. Furthermore with quad packed missiles it means you can comfortably carry enough missiles to ripple fire them at either a single target for added security on the off chance one misses or for satuartion attacks by the enemy.

    As an example the Type 45 destoyer could carry 64 CAMM missiles quad-packed into 16 cells as well as 32 Aster 30. This i feel would better suit the air defense fleet bubble as the T45 would have more missiles to use in the fleet defence role while still having plenty of short range missiles to protect assets when in close escort.

    I really hope that the optimism is right and that structure is an amidships VLS. For myself though I suspect that its the exhaust stack for propulsion.

    I thought that it was the exhaust stack at first as well, mainly down to what i now think is just a reflection/shadow on the left corner of the structure. This gave me the impression at first that it was a pit on either side of the structure for the exhaust but now i think it could be the A70 vls. Im still not positive though one point i keep coming to in my head is it could maybe be a little low for the exhaust stack but im no expert.

    A little off topic but any ideas about ship propulsion? Im thinking it could work as an all diesel ship as this would be more fuel efficent than turbines but still provide enough electrical power for the motors. Another strong possibility is a single gas turbine such as the RR MT-30 coupled with diesels for a more conventional approach currently used.

    That is the fundamental reason why any other deterrent does not work for the UK in my eyes, we are a small island nation full of nimby’s. We dont have the vast acreage to hide silo’s and keep them away from nutters and we dont have enough large airfields to disperse bombers to. Furthermore an airborne deterrent is the least secure, reliable and effective route.

    The greater weight of shot really counts in NGS especially if you are going in against anything fortified in even the most rudimentry of fashion – target effects counts!. RoF for the proposed mount is more than adequate for fire support.

    I suppose it’ll be handy for when we need it and the RM’s should enjoy some bigger booms.I remember the image of HMS Cardiff after doing some NGFS there were also other pictures that showed the aftermath of doing some prolonged firing.

    http://upload.wikimedia.org/wikipedia/commons/6/6f/Aftermath_Cardiff_NGS.JPG

    Why do the RN keep rejecting the 5″ calibre – mostly because it is little improvement in capability over what we have/had. The mounts themselves (if we are talking about the US Mk45 or the OTO127) are arguably quite a bit better than the Mk8 mod 0 – in terms of reliability they couldnt be much worse!.

    I thought they would have sorted the problems with the mount as most of the problems popped up in the Falklands when doing NGFS seems a hell of a long time to have a gun with problems. If the 155mm gun falls flat then whats the options for a gun for the new frigates do we have enough Mk8’s for hopefully 16 frigates and 6 T45 or will we make more. If we need to procure new guns i think it would be worth a switch to either the US or Oto 5″ gun for the longer term support and R&D benefits.

    The Mk8 had the virtue of being developed from a weapon BAE put together for the Army so it had ‘jointness’ appeal plus it was, allegedly, a reasonably cheap weapon. I never saw proof of that mind. Seeing we had already decided to replace Mk6 with the Mk8 that was it for a 5″ the actual effects difference between the two basic rounds is marginal though obviously tips in favour of the 5″.

    Jointness in my eyes is an excuse to procure something that tries to save money but ends up not ideal for the job and has problems. Also ends up costing more in the long run. Cheap in the British sense means it was at least 2 years late had unfixed problems for years and cost 150% more than it was meant to. So im sure it must be cheap in a British sense. Would it have been better in your opinion just to buy the 5″ mount from the Italians or the US? im thinking maybe not back then but i would have considered the 5″ mount instead of the Mod 1. Mind you BAE couldn’t rip us off silly:( if we had bought the gun from the yanks, though BAE now own the company woops.

    I would ideally like to see all of the ‘C-X’ types carry facilities for the maritime interdiction role, since any of them may be called upon to perform these missions. If the C-1s, C-2s and C-3s could all have space for a pair of RHIBs, and space for a detachment of Marines, then that would be a major benefit. Ideally there would even be sufficient space to accomodate the MCM modular gear intended for the C-3. This could allow a series of modular sets of equipment and personnel to be embarked, on any of the ships that will make up the bulk of the surface fleet.

    From what i’ve managed to gather from my readings the idea is to have space for around 30 RM’s or other people in addition to the crew, thats for the C2 and Venator. The C1 i dont think should be able to carry modular mine warfare kit the C2 yes i think should as it could be used for helping out C3’s doing the job by providing firepower and command facilities.

    Although this would increase costs for the C-1 and C-2 a bit, it would give a very welcome boost to capability. The RN could therefore maintain a number of MCM units, Marine boarding parties, and any other modular units that are needed. These units would almost certainly be capable of being deployed on anything from a C-130J or A-400M to a chartered airliner (e.g. a 737).

    Or you could use the Absalon for your C2 role and store the mission modules on the massive flex deck. You could also provide accomodation for RM’s and store their kit as well such as boats etc. Absalon is after all a ‘Command and Support ship’ so could command and support C3’s and all the gear. Better than relying on crab air to get you places no doubt far far away. (Runs and hides for bringing up the Absalon class again:o)

    Two reasons, both from October 2006:
    – France threatened to shoot down Israeli aircraft crossing the border, this was while there was still unloading operations going on with French amphibious ships
    – the crew of a certain German ELINT ship was pretty much unpacking their Stingers after six IAF aircraft buzzed them and fired over the bow.

    Erm! ok, thats news to me seems a step too far shooting across the bows. Next time i would like to send along a T45 and paint the ******s and see how they feel. Nice to see though that the french have good reason, hopefully they add more than Tetral.

    i dont see much of a reason why as i doubt the Isreali AF would do anything stupid

    Im afraid your wrong the IAF would do something stupid. They aren’t as nice as they make out. Oh! wait i said that:D
    I thought all went ok’ish im suprised there was no big media storm and all that if there was sorry i missed it.
