    Again though Wan apart from the SF300, which is scarcely a FAC(M) in the conventional sense, which boat there has more than the most rudimentry of ASW capability. You cant take a FAC(M) hull and build an ASW boat off it thats worth much. A subchaser maybe but, nowadays, we have choppers for that because they are much more capable of jumping ahead of the contact and not getting themselves blown to tiny little bits in the hunt.

    In your own littoral, which is the only operational area for these boats, and within range of your own medium choppers there is very little that a FAC can offer that the choppers cant do with much greater safety and with the potential to cover a LOT more territory. There is a difference between a competent hull and a hull that has had a couple of secondary bits of kit bolted on in hopes that it does a ‘better than nothing’ job.

    Your own quote above indicates that the ASW potential added to the Stockholms was a backfit job to add a needed capability where precious little existed before and you are seeking to back that up with the technology and ASW prowess of the Saudi and Malaysian Navies???.

    http://en.wikipedia.org/wiki/Stockholm_class_corvette
    2x Stockholm class = Displacement: 380 tonnes
    4 × 400 mm tubes for Type 43/45 torpedoes
    4 x ELMA Antisubmarine grenade throwers
    SS304 Spira HMS
    TSM 2642 MF VDS

    Incidentally, same fit as on the 2x 425tn Goteborg class ships and not much different from the fit of the much larger 5x 600tn Visby ships (different sonar suite).

    Which means it can effectively deploy its weapons. Running out of torpedoes in Swedish territorial waters (12nm) does not seem a major issue to me: there’s alway a port nearby to which torps can be helicoptered in if it is not a military port. Besides, support vessels, patrol craft tenders and large minlayers can help out too. Some ASW-equipped air force HKP 4B helicopters (CH-46 Sea Knight) as well. Some nice coastal SSKs for ASW work too.

    Anyway, to the extent they were expected to do ASW, I don’t thing anybody intended these ships to do anything other than coastal ASW.

    I know what the ships are Wan!. The point being made by Maskirovka was that this boat, and the handful of others in Swedish service, prove that FAC(M)’s are more than just seaborne missile trucks.

    The comments you have made above actually support my position that whatever additional capability they mave have its extremely modest and limited.

    So, even if you accept Maskirovka’s very tenuous premise, and believe the modest number of Swedish designs are generally representative of the types of vessel labelled FAC(M)s’, it still requires a great deal of imagination to see the vessels as much more than floating missile trucks!.

    HK,

    IMHO, the idea that the RN is suddenly going to relaunch the Cold War-style DDH concept, when every other navy in the world has abandoned it, is just a pipedream.

    Not so. The LCS-2 is an aviation heavy concept that is in the water. BAE have drawn up stretched 9500ton Daring versions with expanded aviation capability and the UVX escort concept which is DDH+. Just because the Japanese and French have evolved towards the through deck solution (as we did back in the 70’s with the CVS’s) doesnt mean there is no merit in the DDH platform or that it has been discarded in any way.

    Kev,

    I would of thought integrating Fireshadow into Sylver’s would make a better bet for use on C2’s to be honest, it’s been suggested as a possible upgrade for the T45s anyway…………

    Very much. A loitering munition that can provide its own ISTAR product and relay that to the ship could be extraordinarily useful in high persistance, elevated threat scenarios. Be interesting to see if it can be made to fit a Sylver cell.

    One thing I don’t understand: if a 6,000t FREMM is too small for fleet ASW taskings, then how come a 4,500t Type 23 is perfectly satisfactory? Unless you’re implying that the RN’s ASW requirements have changed dramatically, I’m not sure I buy your logic. IMHO, FREEM is perfectly sized for C1, with the main problem being lack of commonality with Type 45s. Anyway, if C1 is based on the Type 45 hull, I’m willing to bet that it’ll be on a shortened hull, not a stretched one…

    Type23 is far too small for our Fleet ASW now. FREMM is too small and T45, as is, is too small. The name of the game for littoral ASW isnt pushing the escort into the SSK home waters, because that is dumb, its sending hunting choppers with advanced dipping sonar or USV’s in….or standing off with an active LF tail banging away to cue in something with a homing torpedo.

    C1 needs to be capable of operating a hunting pair of Merlins at very least and I’d rather see that up to three airframes. Thats not FREMM any more than its T23!.

    I would personally prefer to see cruise missiles and 155mm guns on C2, since there won’t be enough C1s to spare any for land attack. They’re all going to be busy escorting carriers, amphibs and SSBNs. Better let C2 take care of littoral operations (where towed arrays are less useful) and land attack.

    Putting the cruise missiles on C2 means that the vessel needs the C3I systems and capacity to undertake deep strike planning. That is not in keeping with the need to keep the vessel cheap enough that we can get a good number. Basically what you are describing is the land-attack FREMM!.

    I think what you are arguing is in terms of opportunity cost. Now here, it might not be that fantastic as for similar costs, you can get a burke/Type 45 equivilant yourself. That would be true in that destoryers can be used for far missions then and FAC, so FACs = fewer destroyers, so the opportunity costs are high.

    I am thinking in more direct terms as in the cost in lives and material to take out a modern destroyer.

    You are quite right of course that value of one solution over another isnt an absolute. Many factors come into play as to what comprises a good solution to a state’s naval threat scenario. You may be able to buy 3 Khareef-class ships and 5 new build SH-2G’s for the same money as 6 Pr1241.8 missile boats and 4 MPA configured Be-200’s, but, geography may mitigate to one solution or another. You may not have a skilled pool of chopper pilots that you can keep deck qualified. You may not have the technical base in your service to keep an embarked chopper operational etc, etc.

    What I would say as a generalised point though is that the most inherently flexible a solution you can get is usually the optimum one. The missile boat solution I indicated above would, probably, be my choice where I to need a coastal defence force based on limited infrastructure. Basically, especially if I can get the new A-190 gun installed, I get some manner of local patrol and fire support capability from the hulls but retain the ability to present a technically superior opponent with heavy saturation fires sufficient to provide a virtual attrition pause to that opponent.

    The problem though is that the oppositions threat reduction exercise is greatly simplified because the limit of operations of my capability are clear. The radius of operation from home base is reasonably easily defined and the flotilla is obliged to stay roughly together to present volume of fire. The ISTAR capability is similarly tied to fixed operating locations and its radius of operation relatively quantifiable. As an opposing force then I can programme my operations with a fair degree of safety as to when I can put my forces into Defence Watches and stand them up to the threat etc.

    Oceanic capable ships change that calculus though. If I can get the Khareef-class boats and an organic chopper capability for the same money my effectiveness is increased hugely. The opposition force now has to face a threat, with organic OTH targetting capability, on transit not just in theatre. Simply put the opposition has a harder time as they have to sanitise a much greater swath of seaspace before they can be guaranteed safe theatre-entry. Wheras you may need the concentrated missile fire, from a number of FACs, to defeat an alerted destroyer force if you can suprise an enemy unit with half a dozen missiles down an unexpected threat axis you can achieve just the same results.

    For my money, if you can do blue water ops you do blue water ops. Your not going to stop USN battlegroups with a few 2500ton light patrol frigates but the FAC(M) navy next door wont be troubling you much!.

    Maskirovka,

    During the cold war these “missile trucks” were at least used live numerous times in chasing Soviet submarines in Swedish waters. Or patrolling the waters outside Soviet Baltic gathering ELINT/SIGINT.

    And today the Swedish FAC HMS Malmö caught 7 somali pirates off the coast of Somalia. So I´ll guess they can be used as something else then just a “missile truck”…

    …and what is the actual ASW capability of a Stockholm class boat then?. Against a determined SSN do you think that one of these boats would even get a real sniff of an Akula, 688 or Trafalgar before a HWT disintegrated it?. The answer is no and at what price does the minimal ASW capability possessed by the boat come at. You have a dipping sonar and a few LWT’s bolted on plus support and training costs for starters and then you have a primary antiship platform chasing around pretending its a subhunter!. How many Stockholm hulls do they have again???.

    Likewise you can catch Somali pirates with boarding teams from Fleet Auxilliaries does that say anything about the fighting potential of the general fast fleet UNREP ship!!!.

    I see that you are trying to make a case for the Swedish Navy and, as I’ve said, their tactical situation is one that lends itself readily to FAC(M) operations. That doesnt mean that a FAC(M) is anything, realistically, more than a floating missile truck though.

    As discussed before FREMM doesnt work here. Its too small and compromised for our Fleet ASW taskings and too big and expensive for the cheap stabilisation combattant requirement of C2.

    This is why we got rid of the whole FSC concept – it was realised that you cant do cheap patrolling with a frontline ASW hull and cant do frontline ASW with a cheap patrol hull. The Italians and French have different tasking levels and other assets for ‘cheap patrolling’.

    Many people have proposed FREMM for the RN – mostly they are Europeans who hope to get cheaper hulls off the back of a large UK order!.

    If the recent news thats bubbled to the surface that C3 is being detached from the original S2C2 studies is true then we absolutely have to get as much commonality through the combattant fleet as possible. We have a hull that, by all accounts, is revolutionary in RN experience in terms of performance against fuel burn. Why on earth would we not pull through on a successful design…unless we crack near room temp superconductors between now and C1/C2 order!.:)

    As quoted above (doffed cap to Swerve!) C1 needs to be a big hull with lots of space for aviation, tail and systems to explode other peoples stuff ashore at varying ranges from the ship. We have the hull design and experience to do that. As the little furry chap on the advert says ‘simples’.

    C2 is a pig of a brief now though. We still must have commonality….reducing the whole life costs and cost-to-deploy is the only way we make this force structure work. That rules out an off-the-peg design from France or the US, by the time we’ve made it fit with our systems we might as well have designed our own. So we need something with common systems as much as possible with T45 and the potential C1. Between the Khareef OPV hull and the T45 in displacement but likely ballparking 4500tons full load and prob somewhere near 120-130m in length. Some variant on the T45/C1 IEP layout to get the economy…perhaps single turbine plus diesels?. Kit carried directly across from decomming Dukes.

    Only thing that comes near meeting this is the years old BAE Medium Vessel Derivative (MVD) proposal. We will not get the numbers of these vessels that we need to cover all the patrol slots we have taskings for though. If we are lucky we’ll get 9 hulls which is, at most, 4 permanently on station at any one time.

    Unless C3 comes back into focus as a useful patrol hull i.e equipped with a hangar, a medium calibre gun of some description and a competent 3D air/search set as absolute bare minimum we are going face a crippling battle to cover the taskings and, more likely, will face an embarrassing bow out or part-timer contribution in the principle NATO taskings we participate in now.

    If memory serves the Sheffield shots were taken BVR or at least out of visual contact owing to adverse weather conditons and the low altitude release.

    Syrian Osa and Komar class boats launched P-20’s at beyond visual ranges in ’73 at Latakia. Which is the only case I can recall clearly where a long range shot has been taken by a missile boat. Those shots being ineffectual owing to Israeli softkill.

    Operation Praying Mantis saw the release of a Harpoon by an Iranian Combattante-II FAC(M) this however wasnt quite out of visual range. Again the shot was ineffectual in the face of softkill.

    Why were the three ships for Brunei that are still parked on the clyde rejected again?

    Not the excuse given by the Sultanate I’m sure, but, the truth of the issue is that they got a nasty shock when they realised the level of technical support that the, very comprehensively equipped, vessels were going to require to keep operational. The Royal Brunei Navy basically balked at the idea of leaping straight from 200ton 37m light FAC(M)’s to near 2000ton comprehensive patrol frigate’s complete with SAM’s and aviation!.

    I think many navies and sailors would disagree with such a statement. Most pretty modern FACs are quite multirole. The Swedish Stockholm- and Göteborg-class FACs for instance has an emphasis as submarine-chasers. There are offcourse many tasks a modern FAC can do, anything from just patrolling your waters, laying mines and doing SIGINT/ELINT work to anti-ship/sub warfare. It´s not just a “missile truck” on water…

    The Swedish example is somewhat unique, but, the same basic principle holds. They are missile trucks just trucks that are fortunate enough to be able to lurk behind convienient lumps of rock sticking out of the water.

    You make a good point suggesting that as technology has improved more capability can, and has, been built into the modest hulls. As I said though start adding stuff and watch what that does to the sticker price of your cheap ‘asymetric’ warfare platform.

    If you just send a destroyer, even one as capable as as Burke or Type45, against some modern FACs with long range missiles that cost a fraction but have decent off board sensor support, the destroyer gets spanked pretty much every time.

    There are some fundamental misconceptions here. People are still thinking that the FAC(M) is an interceptor of HVU’s – a seaborne strikefighter if you will – thats not the case. The FAC(M) is an AShM missile truck that is free from roads and thats about its lot. Its speed is of trivial significance as it will not be able to run from an inbound missile envelope in the same way an aircraft might. What it offers, like the truck, is persistance in the OpArea. You cant keep a pair of strikefighters in one place for 7 days on end unless you have many dozens of aircraft, aircrew and missiles to cycle through. Remember that missiles, big heavy ones especially, have airframe carriage lives and you dont want to have to decertify half of your arsenal on maintenance/reliability grounds just before the shooting starts!.

    This is where the above comment falls flat to an extent. Offboard support and, if you are shooting 200km+ ranged missiles, its going to have to be good offboard support (unless the missiles are intelligent enough to reduce the targetting overheads required – a la NSM) has to be omnipresent. Its no good having a great powerful multimode radar on overwatch if its back on its home airfield when your threat is coming into theatre entry. So your equation to defeat the destroyer is something like:

    (No. missiles to saturate target defences/FAC(M) SSM battery size) + (4 x theatre targetting asset)

    The good news is that the targetting asset cost item there pays off as it services other shooter assets, as ‘wolf describes, but its still a considerable expense. Obviously the 4x value is for something like a comprehensively fitted MPA which would probably represent about the minimum support you would require. Three airframes to cycle through the flying programme with one attrition reserve.

    Suddenly, with the indispensable support costs for the targetting platform added, the capabilities of 6 FAC(M)’s each mounting 8 LR AShM’s (to have a high probability of success engaging one T45 class destroyer) look far less ‘fractional’ in cost/benefit terms.

    That is also taking a very simple ‘traditional’ FAC(M), such as the new Chinese multihull unit as representative, start adding in 3D radars, SAMS, medium calibre guns, CIWS and ESM/ECM fitouts to the basic recipe and watch what happens to the bottom line!.

    Yes, but they will be used to having an auxiliary deck by the time any PdA replacement enters service.

    They’ve spent effort & money to add that capability. A single CTOL replacement for PdA would imply abandoning it. It also has implications for aircraft purchases & ship ordering schedules. One must consider both the remaining life of PdA & of the Harriers. Selection of F-35B gives more options for the transition.

    I see JC1 as a statement of intent, & a victory by the JSF supporters within the Armada. It gives them additional arguments to use against the CTOL supporters.

    On the first point possibly, but, more likely not. As you say the Harriers will transfer to JC during the Principe’s major refit around 2011. That refit will only take Principe through til about 2020-22 when she’ll be thirty years in commission.

    Will she need much yard time between the end of major refit and decommission?. If not I’d imagine that JC is going to be much too useful in her primary role as an amphib to be spending much time playing aircraft carrier.

    They have spent money adding the ski-jump to JC but that vessel is still very much an amphib with STOVL capability rather than a ‘proper’ CV with commensurate performance. So they’ve not really put all that much effort in to reinforce the F-35B lobby. Likewise I’d call it a very, very modest victory for the STOVL lobby in the Armada at best.

    I dont disagree that F-35B is the likely solution for the PdA replacement. Just the point has to be made that Spain is in a very different situation than Italy here. The Italians have nailed their colours to the mast with Cavour and have clearly declared the F-35B aquisition. Spain has a few years left and can be a little more creative if she sees value in it!.

    This is all true, of course, save for one small fact the Spanish Armada isnt used to and has never, actually, had a backup carrier capability before. Dedalo was thier only flat top when they first inducted the Matadors and Principe has been standalone for the large part of a couple of decades now.

    Failing to take advantage of the presence of Juan Carlos as an auxilliary deck for a STOVL type could be considered inefficient, but, if they are used to programming their operations with only a single deck anyway what is the loss?. Better than nothing perhaps, but, if they are already used to all or nothing and want another option than F-35B/STOVL the logical step would be Sea Typhoon/STOBAR!.

    Talk has been coming out of Spain for absolute years that there is a strong movement for the Principe’s replacement to be a non-STOVL design. The often-touted BSAC design being the likely root-cause!.

    Speaking in pure hypothetical UK CVF studies always placed the notional ‘Sea Typhoon’ in the STOBAR category. The notional PDA-replacement with a Spanish design to the same, rough, brief as the Indian IAC need not be outrageously unaffordable for them. Share logistics with the AF and training with the RN Fleet Air Arm and, at face value, you can see some merit in the concept.

    If, for any reason, UK MoD fell out of love with F-35B, the Joint Force structure and wanted to revisit Sea Typhoon would the numbers be there one wonders?. You would ballpark it as roughly 50 for the Spanish Armada to support a 24-plane airgroup and probably 100 or so for front and second line FAA sqdns to support surge ops of 30 planes for both carriers.

    Obviously the real-world chances of this actually happening are utterly negligable and the operational considerations of shifting CVF to the, much maligned and unloved, STOBAR technique would be significant. In simple numbers terms though would those knowlegeable in such industrial concerns consider a 150 aircraft order sufficient to make the enterprise commercially enticing?.

    How did the task forces transit the large expanses of the Pacific? Was there a major sub threat enroute? Have you looked at a map lately? the island locations where the battles took place have not changed? Was Midway fought in littoral? Coral Sea? How did the USN transit the Pacific from the west coast and Hawaii to the Solomon Sea? ???????…..etc.

    So you are repeating what I said in different language?. The Pacific was a series of set piece battles initally that led to protracted littoral warfare. Can I assume that your unwillingness to answer a direct and very simple question is deliberate?.

    They successfully conducted ASW with far less sophisticated weapons and sensors when needed just as a much larger ship (LCS) with better sensors, weapons, and helos would be able to conduct ASW as necessary now.

    You are still seriously trying to make this connection?. Please, as you have been asked by others, look at the capabilities of the ASW vehicles deployed on LCS. Its chokepoint and shallows stuff. The most ASW support that an LCS will give a deployig group is to sanitise chokepoints in preparation for the group transit. Still vital work and not to be undervalued…..but not blue water ASW by any stretch.

    Your ignorance is showing again. the SH-60/LCS combination steaming in the van of the main body is a superb system for providing AAW screening and early warning. Why, here is a hint….. radar can be detected at far greater ranges than the radar itself can detect and track a target. Maybe you don’t want to give away the location of something more valuable?

    So now LCS is a valid FFG replacement, and an AAW one at that, because it carries an ESM fit???.

    Naval architect you aren’t. Top weight is proportional to weight below the water line. Sure they had a lot of weight topside but they had even more at or below the water line so in effect that counters any weight topside.

    You put weight up high on a ship, armoured directors or heavy radar fits and the suchlike, you will decrease its stability. That stability is restored, in some measure, by increasing the beam/displacement but you always have the tradeoff that beam/displacement brings extra overheads impacting propulsion/range. So its not always possible that the topweight is fully offset. Indeed designers will have a criteria set for ‘operational seastates’ where roll and pitch values will remain within parameters set for retaining capability to fight the ship. The top weight, whilst designed in, isn’t often completely balanced out as many designs ‘accept’ the relaxed stability in the more unpleasant sea states to trade off against the performance advantages of narrower beam and lesser displacement.

    ….and no I’m not a Naval Architect.

    The point I am making here is that while they are designed to excel in the littoral, they also have considerable capability and bring considerable value to the CSG or ESG in blue water. They are in fact probably more capable than a Perry in most sea conditions for ASW. they are certainly more flexible and they have a better AAW self defense than the how the Perrys are currently equipped. they are in fact the new small general purpose escort that the Perry’s and Knoxs once where.

    Which is a view thats unsupportable in any logical sense. Certainly the GD Trimaran has the potential to be equipped in the manner you describe and, doubtless, be a valuable, if pricey, asset.

    As planned currently though neither LCS is equipped for the task. It cant be a successful blue water ASW asset without an organic ASW sensor or weapon. You might as well say that an auxilliary is a blue water ASW platform because it can operate an ASW chopper or two and can mount a SeaRAM!

    You really don’t know what you are talking about do you? The calmer waters of the Pacific? Are you serious? Oh I get it, they named it pacific because it was so calm.

    The Atlantic Campaign primarily constituted repeated oceanic crossings in th face of a developed sub and air threat. The Pacific Campaign was a series of set piece surface engagements that became primarily a littoral island hop amphibious campaign. You tell me which was easier on a poor seakeeping hull.

    But, just to satisfy your stupidity what about ships like HMS Capel or USS O’Flaherty (DE 340). both drew 11 feet of water? They and literally hundred of other similar DEs successfully conducted ASW in the North Atlantic. None of them had particularly deep hulls in fact they all had, ready for this …… flat bottomed (what we call) semi planning hulls.

    What about them?. They were all horrific sea boats, significant percentages of the crew would be debilitated through seasickness routinely. They were never dry internally and in a seaway were generally terrible gun platforms. Do you think, for a single second, that their successes in the battle of the Atlantic translate to anything meaningful in today’s operations?.

    Want to talk about the trimaran? As for the rest of your post, I can’t be bothered but the your comment on where most of the Iowa’s weight was shall we say a real knee slapper.

    The trimaran is a different story and one I haven’t discussed at all. The trimaran hasnt been selected as LCS though has it?. If it does get selected, as I strenuously hope, the situation changes in hull terms. Not sensors though. There is still no utilisation offered by LCS-2 to a battlegroup, on transit, beyond its flight deck. It is still not an FFG replacement. As for the Iowa comment I didnt say anything about where most of the Iowa’s weight was?. I said it had a lot of topweight and therefore suffered for it – the Iowa’s like most BB’s had a lot of weight above the waterline. Simple statement.

    You mean it broke the speed record going across the ferocious Atlantic Ocean? How on earth did it do that? The water must have been like glass those few days.

    At any point have I or anyone else said that a semi-planing hull cant transit blue water?. I started on this stating that the LCS could self-deploy. What point do you think you are making here?. There is something of a difference between transit and operations.

    Convoy escort duty may have gone away but there are still carriers and gators that need ASW. The need remains, LCS does perform it in a different way.

    Yes on transit, in blue water, this is provided by SSN’s and DDG’s. In the littorals this is provided by LCS. Not a complicated force structure really.

    Distiller,

    Seastates above 4 are not so common. I remember a presentation on the Seabase and connector and SS4 covers more than 95% of the year in the mainstream potential theatres.

    What were the mainstream operational theatres discussed do you recall?. Gulf? Med? Baltic?. Places where a Seabase might use as OpAreas?. A 95% ratio of conditions below SS4 in the Atlantic is just not correct. That goes doubly so in the Southern Oceans. In littoral regions I wouldnt dispute it though. Which was probably the justification for the LCS-1 semi-planing hull!
