    I disagree. RN’s track record also disagrees. If these aren’t combatants then why do they need a gun at all???

    The RN’s track record is to send whatever vessel it can lay its hands on and afford to send. Thats why we have RFA’s filling patrol slots for chrissakes. Largs Bay has just completed her first APT(N) deployment – a bloody LSL with a bouncy castle for a damned hangar!. Thats the RN’s track record so I’ve no clue what you are thinking of!

    Why does it need a gun?. Have you even bothered yourself to read the posts on this thread?. I suggest you do – all the answers are there and I have no intention of repeating myself yet again.

    Re Mk8, as you say it’d need development of new ammo, and it’s not that inexpensive the way the UK does things. New-build Mk8s are going to be expensive anyway, and reusing old ones won’t do the whole fleet and would delay time-frames unless you want either the C3 or the previous owner to be floating around without the gun for years due to refit schedules.

    Huh???. What possible need is there for the development of new ammo?. We have piles of 4.5″ shells for the mounts that are deployed now. Why would we have use for rounds other than the HE, Base Bleed, starshell and RF decoy we have stockpiled?. In fact that is one of the prime drivers in re-using the mounts.

    I recall that in late 1990s base-bleed rounds were much more expensive than non-base-bleed ones – it’s about who is making how many not just materials. Even with base-bleed we are still talking about being within the radar-horizon of shore based AShMs.

    Compare the complexity of a base-bleed round to your programmable ammo from your gucci OTO and Bofors mounts. Guess which way the price gradient goes!. Shore-based AShM’s???. Do we currently send our C3 equivalent vessels like the MCMW’s or the OPV(H) into the teeth of shore based missiles?. No we dont. As stated we just had Largs Bay do APT(N) do you think anyone had a Moskit locked on her at any time in her patrol window?.

    The 127mm isn’t any better unless you buy Volcano. Now 155mm would do good shore bombardment if you have extended-range ammo. 27km is about what the Israeli Saar-5 was at.

    Are you serious?. We have a requirement for an economical patrol vessel that can cover anti-piracy and MIOPS patrol tasks, MCMW through the use of UUVs and disaster assistance.

    We cant use front line escorts for these taskings as they are too expensive to deploy and their combat capability is wasted.

    Vospers has come up with a design, on 3000tons, which has the promise of performing all those roles. If we add the old Mk8’s to that design we get improvements across all of its assigned roles from anti-piracy to diplomacy reinforcement to low-intensity intervention. It really is that simple.

    But, if shore bombardment isn’t required or too expensive, go lighter to 76mm or 57mm, at least then you can get to “CIWS” and still do anti-piracy or whatever you need the gun for.

    ….but, once again, we do not have a 57mm or 76mm in the fleet and, AFAIK, are not about to add new weapons systems for our cheap-end capability!. The C3 as Vospers designed doesnt even have a fire-control radar to support such a weapon if we did have a 57mm/76mm and including one would add a couple of million to hulls we are trying to keep cheap and, lastly, we dont need CIWS on these ships!!!. On the nightmare event that a C-802 gets launched on a C3 it would bang out softkill as fast as possible and get out of the threat zone at the rush!. Thats what minor war vessels do!.

    Ed,

    It should also have some form of anti-air self defence system, preferably with some limited anti-missile capability, to supplement the softkill systems.

    No it shouldnt. Radar is trying to push it in this direction because he cant see a 3000 ton warship as an OPV and it surely must have that basic capability even if its only 3P rounds out of a 57mm Bofors. Looked at in isolation what he says does make perfect sense. Unfortunately you cant look at RN procurement in isolation like that.

    What he’s saying, and the comments of the addition of extra gun/missile systems for antaircraft, is still capability creep and, however reasonable, it pushes the vessel closer to the real-frigate end of the scale, as Steve mentions, and great care has to be taken to avoid exactly that. The Mk8 doesnt do this as, well covered here, it doesnt confer full warfighting capability onto a C3….the fact that its only useable in specific sub-warfighting roles is what makes it so valuable.

    One possibility might be to switch from the current 30mm DS30, to something more like the Israeli Typhoon system (mostly because of it’s ability to have some kind of SAM bolted on as well). This could still use the same 30mm Bushmaster that the DS30 uses, but have something like Mistral/Stinger bolted on.

    http://www.msi-dsl.com/photo/nw_sigma.jpg

    No need to go to the expense of changing the mount to any great extent. The above is the MSI Defence SIGMA which takes the basic AUTSIG DS30 and bolts on a couple of Starstreaks or whatever MANPADS you like. Possible option for an upgrade to the ‘existing’ REMSIG DS30’s if threat environments and budgets allow later in the vessels service lives.

    I’m not so sure about Starstreak, especially due to the lack of a proximity fuse, and the use of small darts, which are less useful for anti-missile work.

    As an antimissile or antiaircraft defence I think I’d rather go with the Seastreak/Starstreak than any other MANPADS. This is simply due to the low flight time of the round. A circa M4 interceptor isnt going to let a subsonic dancer get too far into its evasion drill before catching it and the Starstreak-II apparently keeps one of the darts tight to the guidance beam with the other two on wider corkscrews to maximise the ‘hittile basket’.

    Steve

    The problem with this, as i realised when writing my last post, is that we are now talking about a ship with similar capabilities to the Whitby, Rothsay and Leander class frigates

    The strategic situation is very different now to that where those vessels were competent frigates though. It would be a very simple exercise, were it ever to be required, for Vospers (sorry BVT) and the RN to point to other nations large OPV’s and make the differences very clear. Add in a comparitive cost-to-deploy analysis of an OPV of this type and a Type 23 and they should be quite willing to look past any superficial similarities to warfighting vessels. The hard part is going to be showing the difference between this type of OPV and a real, modern, warfighter to keep C1 ringfenced.

    Planeman,

    A stupid move. Inadequate for air defence and inadequate for shore bombardment.

    Its a C3 Planeman!. The gun is not there for air defence as C3 isnt going anywhere its likely to come under significant air threat unescorted.

    Why is a Mk8 inadequate for shore bombardment. The differences between a US 5″ mount and the Mk8 are minimal and with the new, and reasonably inexpensive, base-bleed rounds it can reach out 27km which is plenty good enough and only a few kms off a standard 155mm reach!.

    ashm can be used on different ways e.g. in a bearing only attack with wide fov and without range gates. and esm works in both directions, so why not firing a ashm on a track based esm only? most potential foes of the rn will not care if they hit a neutral ship so i would not necessarily assume that you will see a search radar first.

    The radar-guided AShM needs to have a seeker activation point unless you fire it on a profile to allow it to have a wide FoV and active-on-launch. That itself will trip a shipboard ESM set. Most possible foes of the RN will be concerned if they hit an incorrect target as it will waste at least one missile, probably more, and some of the regimes that might oppose us will not be aided by killing innocent sailors.

    hsiung feng II for example is already fielded with a dual radar/iir seeker.

    Another strange one….I’ve still to see an obvious IR transparency in the nose of that weapon that would make me believe there is an IR seeker there. Unless its in the blister on the top of the weapon that is?. I wouldn’t put the technical capability beyond the Taiwanese, but, it is another one I remain to be convinced of. Even granting HF-2 IIR you’d be pressed to find a third!.

    you do not belief that new technology can turn the tide. nsm for example as a iir only ashm was tested successfully with decoys and distinguished between the decoys and the ship. with a second type of seeker and sensor fusion you can further improve such ashm.

    You may have missed the threads where I gushed about the capabilities of NSM to the point where I was asked if I worked for Kongsberg’s marketing arm?!. It’s not the ‘new technology’ I have a problem with – it’s the old technology that most current and near term AShM’s still use that I have no faith in. Active Radar Homers and passive/active types are great for open, clear, blue water as soon as you get into the littorals or heavily trafficed regions they are next door to useless. That is why the US has left them off the Burkes and is why we are leaving them off the Fleet subs in favour of additional Spearfish or TLAMs.

    you can call sea wolf whatever you want, the quoted range is 6 km so i call it a ciws (11km for crotale and 16km for rim-7 m/p/r/…).

    OK I’ll call it what it is – a PDMS – exactly the same as Crotale, Sea Sparrow and any other short-reaction point defence missile system!.

    my work experience tells me that sooner or later you will reach a point where keeping a old system in service is a pure waste of money. but maybe the c3 will be sold first. 😉

    My service tells me that the RN keep old systems in place a remarkably long time if they work well enough!. Also that ‘wonderful new weapons’ sometimes arent exactly all they are cracked up to be and can take a lot of time and expense to bed down in service. For a vessel that needs to be delivered as effective as possible and as cheaply as possible new weapons systems will be very unlikely to fit the bill.

    i do not make an opv a warfighter, i get it more flexibal and 3p is no “fancy” anti missile ammo, it’s just a flexible pregrogrammable round. maybe you mixed it up with dart?

    Ah ok so the 3P-firing mount doesnt require an interface with a fire-control radar in order to set the fuse rangegate so the round bursts at the correct distance?. Sounds pretty fancy to me. I agree that a mount firing 3P is more flexible…..flexible to do what though?. Answer, as I’ve said all along, is that its more capable of shooting down aircraft and thats about it. Once again C3 doesnt have to have that capability any more than our current minor war vessels do.

    that is not what i sayed. the 76 mm will place more weight in 10 sec or 1 min than a mk8. it’s the time in which you can take down your target that counts, not the number of rounds spend.

    Take down what target though?. The Mk8 mount on an OPV would not be to have it taking targets ‘down’. The only ‘target’ I could see it engage would be shore-based artillery in which range is the key factor anyway or perhaps an opposition gunboat or something equally low-tech in which case, again, range is the key factor. Anything more advanced C3 is going to run screaming from because its an OPV and NOT a warfighter.

    lol. so now you have just placed the opv in a high density warfighting scenario. sorry but the falkland war perfectly shows where you will end without a ciws and this is definitely no place for an opv.

    Who mentioned the Falklands?. I said South Georgia, ie Op Paraquat, a situation which was decidedly NOT high-density warfighting. In that situation a few rounds from a Mk8 and a couple of squads of RM’s, with the ships Lynx over top, could have very well done a job – without all the troubles of deploying an escort group. Classic gunboat tasking….all possible because of the inclusion of a ‘cheap’ big gun.

    it’s also a question on how many guns the shore battery has, 6 105 mm guns e.g. can provide round about 70 rounds per minute, hard to counter this with a single mk8. so at the end with mk8 or not you will evade and call for an airstrike (and to say it again this is a warfighting scenario)

    Sorry that is absolute rot!. Manually laid shore guns against an automatic naval mount isnt a contest. The shore battery is putting the rounds out, but, against a moving target they are hardly providing aimed fire. Against that the Mk8 is putting shells down on the target coordinates at 20 a minute. Nothing beats a naval mount at counterbattery. Where is the airstrike coming from?.

    if you want to make gunboat diplomacy you will not send a opv.

    The C3 is, often, going to be the nearest vessel on scene to any situation around the world by nature of its taskings. If you make the C3 capable of gunboat diplomacy, cheaply, you might just save having to deploy a more capable vessel, of which we wont have all that many anyway.

    yes i would because there is no reason not to do so. that no ciws shoot down a ashm in combat is not a fault of the ciws… but the way out here is to develop such a drone and prove the ciws (and all the other aaw-systems).

    The fact is though what you have here is combat unproven and operationally limited (see Distillers post about engagement windows) systems that you are suggesting are appropriate for basing ship self-defence on. If we then factor in the inherent extra reliability issues present in complex CIWS mounts I cant see how anyone would advocate hardkill over softkill.

    on the other hand there is less time to deploy the softkills in time and to maneuver the ship to improve the effects of the softkills. maybe you have to buy a supersonic business jet to test this 😉

    You are misunderstanding the fundamentals of softkill employment. ARH missiles need a seeker activation offset, rangegate and a bearing that means a defined contact provided to the weapon by the launch platform. In the Falklands War our ESM ops were drilled in identifying the profile of the Agave radar carried by the Super Etendard – ‘Condor’ racket as it was termed. Picking up that signature was sufficient to release countermeasures.

    of course the rcs will change if the ship changes course but it does not explode from one second to another like a chaff decoy.

    Naval chaff, as described above, isnt used the same as an aircraft dispenses chaff.

    rbs-15 mk4 e.g. will have a dual mode seeker with active radar and iir and a more expensive version is planned with additional sar and lpi capabilities.

    Hmmm lets just say I have some doubts about the range of capabilities rumoured for this new variant seeker. I’ll believe when I see it.

    i think there are several ashm under development with similar abilities (they are also useful in a secondary role as land attack missile).

    Which ones?.

    and to distinguish between a decoy and a ship no highly developed algorithms are needed. detecting a special ship between several other ships under all aspects may be tricky but to differ between a diffuse ir cloud and a sharp silhouette of a ship you only need a student research project to solve it.

    See, I’ve heard people say that before, yet it always comes back to the point that softkill does work and has been proven so in many actions – the date is irrelevent as the technology IS proven. We KNOW therefore that its not as easy to distinguish between decoys and actual contacts as you try an make out.

    the type 23 has sea wolf, another ciws with similar range limits won’t be that useful. for the burkes i think only the us-navy knows why they go without ciws, i would assume cost issues (why do they not carry harpoons, do they want to rely on the sh-60 only?).

    Sea Wolf isnt a CIWS any more than Crotale or RIM-7 is. The USN can afford to mount Phalanxes on anything they want…the new Burkes dont carry CIWS because it is assumed that ESSM and Nulka/Softkill is sufficient. Harpoon isnt carried as there is no target set for it.

    and btw why do you move the softkills now to the inner layer, i think the preferable way would be to confuse some ashm first and to shoot at the remaining. there is no much room to use decoys at the lower range limit of sea wolf.

    Softkill is inner layer by definition when compared to the outer layer engagement zone. The way you are describing softkill is exactly the way I did – primary responsibility for inner layer defence goes to softkill with CIWS catching leaks. The conclusion of that being softkill, at full effectiveness, would render the CIWS unnecessary as there would be no leaks. Obviously if you can have both you would, but, if you are to do without one…it would be the hardkill you would sacrifice.

    if your ammuntion is durable for the next 30 or 40 years and you have enough of them, if you have every part spared in numbers which are enough for the whole c3 lifetime, … than you are right.

    Mk8 ammo is bought in batches to maintain stockpiles and is available from commercial sources – Brazil, for example, will be using the mount for the next few decades so even if we were to discontinue our own ammo sources obtaining more would hardly be difficult. Spares costs for keeping the mount in service will be miniscule compared to buying in new systems even if you have to manufacture a few bespoke components.

    for the anti surface it’s the question of whats your target and goal. if you want to sink a large ship, the mk8 is the winner (but it’s also a very hard job to do this with a 114mm), if you want to shoot at a fast moving target (also outside the range of your small guns) go for the 57mm or 76mm. 3p and 3a plus are also much more flexible in most situations.

    I promise you slamming three or four 4.5″ shells into most ‘large ships’ will serious degrade that ships operations. 3P and 3A ammunition? – so we are still trying to make the ship a warfighter eh Radar?. So not only do we need the new mounts we need the fancy antimissile ammo?!. This is just not necessary for the OPV mission.

    you can decide how to react in asym. warfare scenarios and limit your lethal force. for a opv which should not be used as a warfighter this sounds more interesting to me than a 114mm ngs mount. (and i think you know that seen over time a 76mm will deliver more metal to a target then a 114mm because of it’s rate of fire)

    A 76mm will have to fire a lot of rounds to place the same weight of fire as a few 4.5″ shells, and, at nowhere near the range.

    are you serious about your “scenarios”?

    Perfectly. The Argentine garrison on South Georgia gave up when a Mk8 started firing on it and coercion ops are much more effective when you have real naval artillery…not a glorified anti-aircraft mount!.

    if there are some 105mm shooting at you, you will evade and get out of range in any case and then call for an airstrike. countering fire with a single 114m mount is not a good idea. without accurate target data and the right ammunition you will lose the battle.

    We’ve had Mk8 mount ships in artillery duels with shore batteries – they didnt loose!. Use the ships flight for spotting and the advantage is with the automatic, computer controlled naval weapon over the manual operated, manually-laid shore battery.

    the problem is that your points “cheap”, “ngs” and “non warfighter” doesn’t matche each other. if you want to go cheap take a 30mm (no ngs, no warfighter), if you want to have ngs you are not that cheap and you are in a warfighter situation.

    Nonsense. Ships main guns have been used for coercion and gunboat diplomacy for hundreds of years. WIGS tasked ships have used their Mk8’s to make druggies pay attention. Both are sub-warfighting tasks that are manifestly better performed by a Mk8 than anything lighter.

    Distiller,

    Distiller I think a C3 is more likely to attack a land target with a missile than a gun. Also I wouldn’t dismiss the air threat, where the Mk8 is limited by its max 55° elevation.

    I cant see, in any concept of C3 to date, where a land attack capable missile has been put forward as even a remotely possible equipment fit. I’d imagine, to keep within the bounds of financial sense, the only such missile on a C2 would be the blkII Harpoons and the land-attack capability limited to fixed targets and GPS direction.

    As to the air threat, its not dismissed, but its also not considered for this vessel any more than it has been for any of our serving minor war vessels or for analagous hulls in other navies. Units like the new Dutch OPV or the, oftmentioned, Thetis both may have OTO76’s but they arent the new, bells-and-whistles, guided round capable versions….they are the old Compatto variants refurbished to provide a cheap capability. The AAW offered by such mounts isnt massively greater than what could be provided with REMSIG guns and a few MANPADS stowed aboard and rightly so.

    These are not warfighting vessels and, just because they sport a medium calibre gun, shouldn’t be considered as such.

    Ed,

    Having the physical space for the Phalanx to be bolted on isn’t too unlikely, even if there are no true intentions to actually fit the system. Similarly, it may even be possible to bolt a small CAMM launcher onto the work deck, tied into the ships existing systems. This may add some cost to the basic design, but would probably be useful for the potential export market. It doesn’t turn the C-3 into a frigate, but would at least give it more ability to deal with more hostile situations.

    For-but-not-with for additional weapons is fine provided its played down until we have the C2’s coming down the slips. The problem is modular capability like that you are proposing is the very worst kind of capability creep. It gives the impression that the vessel is capable of more than it routinely is, which gets other necessary projects binned and, when you need that modular capability in the field, you find out you dont have it available. Huge loser that one.

    I am not arguing about the effectiveness of soft-kill or CIWS, but rather that in the event we need to put the C-3s in harms way for their MCM mission, then we need them to have as much in their favour as possible! We will not always be able to just avoid sending the C-3s into harms way, precisely because one of their main roles will be MCM.

    There is a difference between opposed MCMW in an advanced threat environment and that in support of ops like Sierra Leone. Mine Warfare is THE best form of asymmetric warfare in the naval spectrum…even the most banana-ish of banana republics can buy a few dozen ground influence mines on the black market and, sown in the shallows and covered by a battery or two of 130mm towed artillery, make a good stab at forced entry denial for a much more advanced intervention force.

    Currently with the Hunts and Sandowns the MCMW work would not be able to start until the artillery could be neutralised by external forces. A deployed C3, perhaps on station ahead of the main group, could quite easily get a spot off its chopper, kept out of MANPADS/trashfire envelope, and engage the artillery itself.

    That being just one of many potential uses for the gun. None of the reasons being vital to the performance of the C3 mission, but, for the likely costs of swapping the mounts over it seems daft not to have the extra capability offered.

    Last point for all those who still want a warfighter for C2 is a point towards todays news that we’re putting the B2 T42’s at extended readiness!. We really have to start getting a grip on our routine patrol deployment costs or this will just keep happening until we have a fleet of shiny and terrifyingly beweaponed frigates and destroyers that sit at anchor because we wont pay for them to be deployed!

    EDIT: Just checked and the Thetis doesnt seem to have refurbed guns as I thought they did. They mount Super-Rapido’s…the point still stands that one SR plus a single fire channel does not make the ship a warfighter.

    and i do not want to call a system proven just because of results which are 30 years old.

    Yet you would advocate CIWS hardkill, like Phalanx or Goalkeeper, both systems first fielded circa 1980 and designed some years before…something on the order of 30 years old…that dont have the positive combat record of softkill techniques?.

    i do not see the problem with the ciws. imho i can easily collect more data about my own ciws than on how an enemy seeker will react on my decoys.

    How can you though?. The CIWS could only be considered as effective as the drones you test them against. You make the point as to quantifying the nature of the threat systems ECCM characteristics, well, in the same way how are you sure that your target drones are replicating the terminal evasive manoevres that a C-803 would take, or a Kh-35 etc, etc. What do you have in the inventory that could replicate a 3M-54E Klub?!.

    Softkill doesnt care about the kinematics or terminal evasion capabilities, in fact, its likely to be more effective as an inbounds terminal velocity increases as the missiles seeker window is that much smaller for refining its target plot.

    and do you really know what the seeker want’s to see? do you know how a seeker will react if a 10.000 sqm rcs just blows of next to the target? maybe it can discriminate between false targets and real ones, maybe it just rescans for a target which is most similar to the target which was tracked first, maybe it makes a random choice (=> 50/50 for seduction like scenarios). with modern microcontrollers you can implement so much different algos to improve the seeker.

    Not really. The ARH seeker head can never, really, be all that discriminatory because of 1 key problem – target aspect. A ship bows on compared with a ship beam on are two massively different RCS profiles. How do you tell a missile to disregard a contact of x or y sq.m in favour of RCS z when you have no way of knowing what RCS the target will have in the first place!.

    What can be done, as the missile closes in, is to give the seeker a higher prf capability to paint a rough profile of the target and this is a fairly standard capability…look at where the hits on Stark and Sheffield were. Problem is that the weapon is already commited to one target before that prf shift occurs though. At the moment, predominantly, and even near-future AShM’s are still, in the main, passive/active RF looking for an RF gradient and emissions on a bearing to filter out chaff clouds and floating passive decoys. Doppler cant be relied on because its common for a ship to present beam aspect to unmask its mounts/directors and so wouldnt have any doppler for the seeker to key on.

    So what does that leave – IR centroid homers – off the top of my head thats the P-20 Termit and (at a stretch) Penguin and dual mode RF/IR load decoys are nothing new to counter them. Lastly IIR which is potentially terrifying, but, so far is fitted to one antiship weapon only and with precious little seemingly following it. Also IIR does demand a certain level of pre-preparation before it can be employed and exploited fully.

    i would also have some of them on my ship but nobody relies on them so a lot of ciws are installed. if the decoys confuses some ashm, thats fine but if not there will be a ciws to clean the skies.

    Not so, find a CIWS on a T23 or a late FltIIA Burke – while both have excellent ILMS both are tied to fire channel limits for those systems. If the softkill isnt relied on, as the only layer inside the ILMS, why no CIWS?.

    established logistics stil costs money. my idea is based on sharing some of them with a lot of other users instead of paying them alone.

    What costs money is inducting new systems and developing the logistics and support infrastructure. What still costs for the Mk8 support chain?. Ammunition…we have, spares….we have, training….we have. Yes there are costs involved in warehousing, shipping and training new maintenance and operations people in support of the system but these are negligable compared to starting the process from scratch.

    a 57mm or 76mm will outplay a mk8 in any roles besides ngs. and i do not see a scenario in which a non warfighter can provide ngs and is not threatened by planes or ashm.

    Anti-surface Mk8 is also far more capable than the smaller calibre mounts. The 57mm or 76mm only has an advantage in anti-aircraft over the Mk8 and if there is any potential threat from aircraft there are the DS30 guns and even MANPADS that could do a job as effectively. Realistically if there was a significant threat in theatre we wouldnt be sending a C3, but a C2 instead. Just as we wouldnt send an OPV(H) to patrol the northern Gulf!.

    is there any “low-intensity” scenario where ngs is needed but where you can be sure that there is no ashm. i think the hanit has shown us that this scenario will not appear. a 30mm has the advantage to be cheap but a mk8 is not that cheap and it’s not that useful so i would go for a 57mm or 76mm.

    Whats expensive about a Mk8 we’ve already bought and would be re-using when compared to buying in Bofors or OTO mounts?. What scenarios exist that could see a non-warfighting NGS mission…how about scaring scrap metal dealers off British territory as an example. Coercing a small garrison to surrender by lobbing a few shells in. On MCMW tasking what happens if, in the opponents littoral, a 105mm shore battery opens up to chase you away. Whats a 57mm going to do about that?.

    For a warfighting role, Radar, you are right the 57mm or the 76 would allow the C3 to make much more of a fight of things. The point of the C3 is precisely NOT to make a fight of things with an advanced enemy though. It should be a cheap, long-range, multirole OPV and a big gun on the front won’t and shouldn’t change that.

    Some nice touches there. Not too sure about the semi-swath part or what the difference is between your COGAG plus electric waterjets and conventional IEP driving waterjets would be, but, its your hull!.

    I like that A-Frame sensor mast concept, but, would point out the need to go ‘aloft’ occaisionally to work on the masttop arrays, so, making the ‘legs’ wide enough to allow for internal access to the masthead would be appreciated by the engineering dept!.

    Why have the strike length VLS amidships?. Why not site them between the peripheral CAMMs cells (single row of A35’s port and starboard?) on the foredeck. That way you could move the prime mover turbines amidships if not at maindeck level then perhaps a deck or two down extending up into the superstructure. Advantages would be the isolation of the primary source of vibration, ease of access for maintenance plus ease of installation and the freeing up of space below the waterline for additional bunkerage.

    Otherwise rational, comprehensive, weapons and sensor fit. Good aviation capability and potential for good range and seakeeping. Overall just as likely to see the light of day as Frosty’s Command Ship or my joint C3/C2, but, certainly interesting in places!

    Frosty,

    Completely, absolutely and utterly absurd!. On the basis of the pitch, tone and duration of the squeal that the beancounting gnomes in Whitehall would let out on seeing this though – I love it!.

    i think there are hundreds of weapons systems spread around the world which are never used in combat situations. only because a system was never used in combat does not mean it’s not effective.

    Doesnt mean its not effective but its certainly not proven. In the context of this debate that is enough for me. As I said my view here is that CIWS has a place, but, that is backup to the softkill. In otherwords you let the softkill distract, seduce and deviate as many inbounds as possible and use hardkill only any weapons that may leak through.

    (fortunately) there is not much experience from real combat situtations to base modern naval warfare on but this is not only related to ciws.

    Yes there is a wealth of combat experience – just none of it is relevent to CIWS as, for whatever reason, where antiship missiles have been fired CIWS has either been unavailable or, somewhat tellingly, inactive.

    so there was a gap between the test scenarios and the combat situation in the falkland war. why do you think that proofing softkill-systems is more reliable than testing ciws?

    THAT is the major problem…can any test serial accurately reflect every potential threat scenario that could be faced in combat. No – of course not. You therefore have to look to the systems with the widest possible set of operational parameters and, any way you cut it, that is not conventional closed-loop CIWS.

    if i never test my ciws with very low flighing targets in front of land clutter i do not know how it will perform here. same to the softkills.

    Not so and this is the crucial difference – softkill will work regardless of aspect, evasive maneover, speed etc as it works on the one really weak element of the inbound. The guidance section. You show a seeker what it wants to see and the seeker will fly to it and thats the bottom line.

    do you think the “low acceptance among navies” is caused by missing knowledge they have? the problem is that you need a highly automated and integrated combat managment system to use your decoys effective in a fast emerging combat situation.

    To be honest Radar I dont believe that there really is a “low acceptance among navies”. If you look around at the more modest naval services softkill is a repeating feature of even quite minor combattants and the developed services are all replete with every kind of decoy, jammer and obscurant. The perception is that hardkill is ‘sexier’ than softkill definitely – its obviously hard to argue that a radar-guided gatling-gun spinning round and letting rip thousands of rounds is anything other than very cool – that is little to base a ships defence on in reality though!.

    this may fit to a adequate frigate but if you want to build a low cost opv you will end up with a small decoy launching console on your bridge.

    Every military vessel now needs a halfway competent ESM system and fortunately they come quite cheap these days. If you have that all that is needed is a competent operator, good leadership and a small decoy launching console on your bridge!. I would, personally, be more confident going into a low-modest threat scenario equipped in that fashion than if I had no softkill but a Phalanx bolted atop the hangar.

    in general i do not belief that we will see a mk8 on the c3. if we want to have a really cheap solution we will see the 30 mm on it and if we want to have a good solution we will use the 57 mm or 76 mm.

    I dont believe we’ll see the C3 or C2 the way I want to either. Simply put I do not believe that many will see, or be willing to accept, the paradigm shift that needs to happen in the RN surface fleet. So i think you are right we wont see Mk8 on C3.

    a mk8 isn’t that useful on the c3 and if the c1, c2 and type 45 will change over to 155 mm than it would also be no cheap solution because a lot of money has to be spend to keep all the logistic chain in service for the c3.

    The money for the Mk8 logistics chain has been spent already. The rounds are stockpiled, the maintenance train established and the sparing paid for. Keeping that going, even for just the C3’s, is far and away a less costly proposal than bringing in a new mount and starting the whole process over again.

    What does a 57mm or 76mm give C3 that Mk8 doesnt?. Anti-aircraft capability?. When is a C3 going to be shooting at aircraft?. The Mk8 mount on a C3 isnt to make it a warfighter….C3 isnt a warfighter. The Mk8 is to confer a coercive presence for the ships patrol taskings and could be used for limited NGS in support of its MCMW and in low-intensity scenarios. In that sense its a LOT more effective than the likely alternative – a DS30 and, IMO, actually more useful than either a 57mm or 76mm would be.

    So to summarise:

    MiG-31’s spend all their time on patrol at 70,000ft and no information, whatsoever, on current VLR AAM’s testing, production or service entry has been released. Which is fine because its not necessary to see any confirmation of a missile existence, or record of its capabilities, because we know that its (possible) launch platform has uprated engines.

    I think that shows all I, personally, needed to know Star thanks!.

    So missile fired from 26000 feet is same as fired from 70,000 feet? And it was old missile. Nothing revolutionary interms of proplusion.

    MiG-31’s are often found patrolling at 70,000ft are they Star?. Would seem a rather curious posture to adopt if one was seeking to engage ‘aerial targets, including stealth ones at small altitudes and long ranges’ wouldnt you say?.

    6 minutes is total burn time of new missile according to report of Vympel from 2006…but It has nothing to do with missile test fired in 1993. which is completely irrevelant to discussion of 2008.

    6 minutes flight time is 6 minutes flight time and that adds up, for an E-3 at its listed maximum speed, to about 70km travel – presumably on a reciprocal course to the threat bearing. Understand the difference between a missile fired in tailchase and one fired at a closing target. The only confirmed missile flight is the test earlier mentioned that used a local designator Flanker to CEC in a longe range missile shot from a MiG-31.

    of course the first two aircrafts were delivered this year with missiles. and those missiles were prevented to be shown at MAKS 2007.
    Read it can intercept Small/Stealthy/long range at same time.

    Nothing in that article about missiles. It also doesnt say ‘intercept’ it says “The upgraded aircraft can detect aerial targets, including stealth ones at small altitudes and long ranges”.

    U also have to accept the fact that MIG-31 was flying at only 8000m and certainly not at full speed. and missile is modification of old R-33.

    Why would I accept that?. Its utter nonsense 8000m is over 26,000ft – hardly nap of the earth and, by Seans word, it uses a loft profile so launch aircraft impetus loses much of its significance.

    So physical performance of AWACS to run is pretty much meaningless. It can hardly move 80km or during 360 sec burn time of latest Vympel very long range missiles

    Basic mathematics Star. E-3 top end is 700km/h give or take a few. You say that it takes 6 minutes for your missile flight to target. Sooo that means your 300km ranged missile fired, as you say, at maximum range is going to fall 70km short of its target when it comes to the end of its arc?. So to get the E-3 at maximum range your MiG-31 is going to have to close to 230km to take the shot….a mere 140 miles in old money. You think someone is going to leave a high value unit like an E-3 so unguarded as to let a MiG-31 get that close unchallenged?.

    This should be alot each MIG-31 should carry 6 of them. New feature of MIG-31 is two datalinks with ground control over hundreds of kms. it can guide missiles till the end. no need for missile seeker to become active.

    Yes very good Star so the Russians have re-invented CEC I’m sure we’re all very impressed!. These 6 missiles that the MiG-31 is carrying, sorry ‘should’ be carrying, they are in the inventory now are they?.

    So Star you accept that the 300km shot was head on and not tailchase now do you?.

    So, if our targetted AWACS where, perhaps, to turn and try to put as much distance between it and the Zaslon ‘illuminating’ it you’d accept that a 300km ranged missile might just fall a little bit short?!.

    F-22 cannot save AWACS when MIG-31 itself can destroy hypersonic vehicles and small missiles. And second F-22 are limited in quantities either they will be in Pacific or EU but highly doubt both places at same time. MIG-31 are at both places.

    Very true….but how many 600km missiles are there?! :rolleyes:.

    Trimaran C3 hull with forward structure influenced by Vispy.
    http://i36.tinypic.com/2m832vs.jpg

    Helipad compromised by large work deck aft for minehunting/sweeping. Also ASW etc.

    This requires hetlipad and hanger moved further fowards. Hanger is offset to starboard.

    Its another great piece of artwork Planeman, but, what you’ve drawn is effectively a Meko A200 with a couple of outriggers bolted on. What advantage does the trimaran layout actually give you here?. You arent getting extra hangar or accomodation off the extra beam and you arent taking advantage of the stability for a tall sensor mast. You have a work deck alongside the hangar (presumably?), but, the outriggers are going to render any over-the-side ops difficult?.

    Hard to see, really, what advantage this design offers over a moderately stretched A-200 incorporating a stern work deck aft of the chopper pad?!.

    this could be done by increasing the mtbf of the system or by making it fault tolerant by reducing/eliminating the single points of failure or by duplicating the ciws systems.

    Most chaff expend launchers are simple tubes fixed to fire in a given arc to deploy loads appropriately. I think you are gravely miscalculating the difference in complexity and reliability of the two systems. Duplicating systems, in the Soviet/Russian model, is the way around this of course. It is ultimately a poor solution though. The purpose of a warship is not to carry self-defence weapons – it is to deploy combat systems to meet the threat it is targetted at. In the context of the discussion here its whether a circa £80mn austere patrol hull absolutely needs a CIWS mount. A question to which the answer is fairly straightforward.

    the corollary would be not to put a radar on a ship because it’s mtbf is much higher than the mtbf of a binocular.

    It is worth the observation that binoculars on a ship tend to see much more use than radar!. You make a good point, but, it does have the flaw in that the binoculars cannot do what radar does. That does not apply to the softkill/hardkill debate – softkill is proven to be able to defeat AShM. In fact, I believe, no CIWS or PDMS has ever destroyed an inbound warshot AShM and the nearest that we have come to seeing hardkill work, in operational environments, is the Sea Dart shootdown of that Iraqi Styx.

    the right way is to improve all the systems constantly to have as much of them available if we need them. and if i take a look on how widely spread ciws are today there can’t be a huge reliability problem. and they are well tested against both drones and real ashm.

    If you’ll forgive the flippancy SeaWolf was ‘well tested against drones’ as well as targets it was never expected to perform against. Its trials reports glowed based on the missiles performance. Those trials meant precisely nothing a few years later when failures started costing lives.

    60 seconds also makes a minute. a srboc for example has to be loaded round by round. with 6 barrels on a single mount one minute per mount would be a good time. on the other hand there are fast reload systems for phalanx which make it possible to reload it in less than 5 minutes.

    You slide a round cannister into a launch tube – it takes no longer than loading a mortar!. Even loading 6 takes less than a minute and then, once the loader has cleared, the mount is ready to go. Phalanx you have to open the feed system, load in a belt of however many hundred rounds, verify the feed, close the system and then get clear.

    re-initialising should also be possible in “next to no time” because usually the ciws is integrated to the ships combat managment system which will provide initial target information and engagement order.

    You’ve still got to take the radar from standby back to radiate and then let it track form…more time taken. Comparitively, by this point, the decoy launcher has probably already fired its next salvo and is reloading, if necessary. Remember that, whilst an offboard decoy (unless its a float) may have a short lifespan the seeker window on an inbound is also equally short.

    ..but in a streaming attack it can handle 3 or even 5 ashm until it runs out of ammunition (gun based). in this case the decoy launchers will run empty first.

    Depends on the installation surely. Terma’s DL-12T system (as fitted in the Thetis boats) mounts up to 24 tubes fully compatible with standard 130mm decoy rounds. A usual pattern ‘per engagement’ would be 4-6 rounds with sufficient time between salvo’s to reload the tubes if necessary.

    there are two major issues here:
    – only because their softkill worked, it does not mean that a hardkill systems would not perform equal or even better. there was no adequate ciws 1973.
    – a match result between a and b which occured 35 years ago does not necessarily means that another match today between a+ and b+ will result the same way.

    The simple fact is Radar that softkill has worked and worked well where it has been deployed. Radar seekers on missiles have not undergone much of a revolution since the Russians dispensed with spin-scan on the P-15!. An AM-39 seeker is still largely recognisable on a missile completed today as one that flew under the wing of a Super Etendard 26 years ago. Yes faster and better DSP’s and processing algorythms have improved clutter-rejection and ECCM, but, the soft-kill techniques have benefitted from the same improvments. Chaff and the AOR’s available today, like BAE Siren, in combined pattern can mess up passive/active seekers a treat and not just one or two at a time.

    “With all these different IR and RF grenades and rockets for short-, medium- and long-range deployment for confusion, distraction, or seduction in combination with jamming devices, hard kill, ship maneuvers, etc., the use and the understanding of countermeasures is too complex……Low acceptance among navies for shipboard countermeasures is not so much due to a perception of overall low effectiveness of the technology, but from insufficient predictability in action.”

    You must see what is written above Radar?. All he says is that softkill is a complex topic and that the general perception is that soft-kill is difficult to quantify in effects terms. Just because there is a ‘perception’ that soft-kill is not as straight forward as hard-kill does not make it less effective – it just means that you have to know something about the techniques to quantify it.
