Sea State 8 i would classify as bluewater capable.IMHO, waste of money for australia. We're responsible for policing and managing through our territories 1/9th of the worlds oceans. That means that warfighting roles are "real" bluewater roles (wrt Oz budget limitations and bang for buck issues)
bluewater capability is not defined by sea state numbersSea State 8 i would classify as bluewater capable.
You're joking?? How the hell would we have intercepted any of the poachers in the last 8 years at the transnational level? Planes can't do VBSSThough I believe Australia only requires a greenwater navy with assistance of RAAF for patrolling larger area's.
I suggest that you resarch all our territorial responsibilities and then tell DefMin and Maritime Command how to fix it then.. Better still, tell Alex and he can pass it on.Having ships patrolling 1/9th of the worlds ocean is far from effecient.
So you'd want to use a high speed BE based for the Indian Ocean or Bass Strait intercepts? Good luck to the crew for that little jaunt. Crikey we almost broke an ANZAC in two doing that recently, a BE based hull trying the same stunt would result in us calling in additional rescue asetss to recover them on the way back.Aircraft can patrol a larger area in a fraction of the time. The high speed LCS design makes a good interceptor if something is detected by the RAAF.
You can't add AEGIS, For crying out loud, read the posts of people who actually have been involved in integration projects.Sea State 8 is pretty extreme and more than good enough enough for Australia. The LCS could easily perform the roles of our current frigates and if AEGIS was (which i believe it could) added it could perform the role of our future AWD's.
In that case, forget the surface warfare role and just make them fisheries inspection vessels. Better still, if thats the job, then turf them altogether and get a mission specific asset to do it instead. If Lab get in then expect a coastguard and more Roebucks - not an LCS legacy assetYou wouldn't have to add AEGIS to all the LCS ships either.
Maybe you should listen to some of the RAN and USN guys who have explained the minimum manning levels and why they exist.The high levels of automation would allow the LCS to perform the basic role of an ANZAC frigate with large reduction in crew size. This in my opinion is the biggest reason the LCS should be considered. You have the option of running a skeleton crew for basic patrolling duties with the ability to fly in extra crew in an emergency.
And your maritime doctrine and threat assessment for this is based on what?When crew shortages become a problem for the Navy you have to find a solution. Adding more large ships with huge manning requirements such as the AWD and LHD's are NOT a good option. They are such a bad option that if we did go to war in our region it may come and bite us on the ass.
Funnily enough, when Coastwatch and the contractor had to put in their submissions 3 weeks ago, they made it pretty clear that air cannot do the job. BAMS and LR-ISR/ASW defacto GMTI does not provide the solution. They are comlimentary solutionsAs with any job if you dont have the crew or equipment you have to outsource. The only solution is Global Hawk and P-3/P-8 aircraft. If Global hawk can reduce the requirement of a single frigate thats 100 sailors that are well needed elsewhere.
So, now you want to remove redundancy, fire teams etc because you think that we can halve the crews? we already know that 180 is the base achievable figure before the risk curve goes in the other direction. We di not want minimum citadel based teams for a reason, we don't want minimum "below the waterline" manning levels either. The number 180 hasn't been pulled out of a hat - it took a number of years to prune it down - and at the same time the USN was also looking at achieving similar levels, they decided that for a given mission requirement, that they couldn't either. Reduced manning achievements between RAN and USN for similar vesels is not relevant as they have different manning requirements.Based on the US manning requirements and the extreme automation of the LCS i wouldn't be surprised if it could perform the role of our ANZAC ships with as little as half of the crew considering we train our sailors for multiple roles reducing the crew compared to the US. An LCS with bolt on radar and a few helicopters could perform the role of the AWD with the manning requirements of our current ANZAC frigates.
You can't retro a cat hull. It has to be factored in at centreline or you start to screw up vessel flexibility.The LCS using modules allows for upgrades to be performed easily and automation increased which would offset any increase in crew as more useful features get added.
The radar, computers, support equipment (cooling skids, 400hz power, ect) and missile launchers will still be hard mounted on the ship and not in modules.That is true, however the new AEGIS being incorporated in the DDG-1000 hull form is lighter than the AEGIS system used today. If you keep the hull and modify the superstructure it is possible to put AEGIS on the LCS. It would be interesting to see the propulsion performance loss on that design, because I bet speed would be the first thing sacrificed.
Cargo carrying capacity and fire power? The designs has a DWT in the order of 400 tonnes and mission package weight of just 180 tonnes for the GD design and 220 tonnes for Lockheed. Using the same hull any additional equipment has to be supported wihtin this DWT (or other gear is removed) as the vessels havelimited cpacity to accept a deeper draft if they are to perfor as expected and to avoid overstressing the lightweight structure. Lets not confuse length with displacement noting the LOA of 127m for the GD design means there are not small ships they are just lighter than contempory steel vessel of the same size.All ship designs are about compromise though.
The Littotal Combat ship is an excellent compromise between speed, cargo carrying, firepower and running costs..
Yes it would be slower (fastest MEKO 200 varaint can reach 30knots) but sustained cruising speed would be the same and the heavier vesel is laikley to have longer legs. Dont for get the max speed of LCS is only achieveable in sea state 3 and is a 'sprint'. The LCS will burn the fuel its fuel very quickly at high speed as the cunsumption is basically logrithim at higher speeds even wiht a high speed hull.Being limited to sea state 5 is due to the fast and light design. A ship that size could have been built to handle sea's that were much worse, but it'd also be much slower, heavier and probably also have less cargo space...
Sorry to be trite but we are talking about earth I assume. This is nonsense. If you get a copy of ocean routes of the world you will not it has charts showing the percentage frequency of wave height. For much of the year north of 20N and south of 20S you have greater thana 10% chance of waves exceeding 3.5m (the greater ocean area in the southern hemisphere). However, even the areas either side of the equatorial zone are subject to the extremes of of weather as these are the cyclone/hurricane zones. The intertropical convergance zone is calm (it alos moves) but this is only a limited area.99% of the time the sea's are below sea state 5, so why build a ship to take into account that 1% when it will cost twice as much to buy an operate.
For all the reason above I completely disagree. How can a 2500 tonne light weight vessel hope to compete with the persitance and uplift offered by the LHD. You wouel need 6 just to carry the 12 troop lift helecopters.I believe the LCS is the perfect ship for Australia. It could replace the ANZAC's and help perform the amphibious assault, transport and command centre roles that were originally planned for the Canberra class ships..
I assume you are recommending the GD design so don't forget that 180 tonne limit. To do the AWD job it will need AEGIS (even if newer systems are lighter), associated FC radars and the VLS themselves. Loaded with SM2 a Mk41 VLS moduel weights in at 25tonnes. Sea sparrow is 26tonnes and I believe the ESSM quad pack load is quite a bit more. (Sea sparrow launch weight is 225kg and ESSM is 280kg and there are 4 of them)In fact if you installed AEGIS as a weapons module onto the LCS it could fill the role of the Air Warfare destroyer fairly well.
I believe Australia should put its foot in the door and start ordering a couple LCS once the price comes down.
The GD design has a lot of bouyancy aft IWO the outriggers but the mass sesms to be concentrated near what appears to be the longtitudinal center of floatation looking at the superstructure. I have to assume that the designers have looked at LCF when considering module configuration and in any case it is not hard to produce a stability package that allows the vessel condition in respect of its static and dynamic stability to be determined for any given load out. Almost all cargo ships are equipped with computerised stability systems.Alexsa that is great information, leads me to some questions.
When I think about the LCS, my first thought is modularity. Those modules add a lot of weight, or at least some of them do, while other modules don't add as much weight. Given the module bays for both LCS designs are at the rear of the ship, how would a heavier mission module effect the LCS in higher sea state compared to a lighter mission module? If you were guessing, would either the GD or LM design have a leg up on the other in dealing with this potential issue?
Because the weight isn't balanced throughout the length of the ship, rather confined to the back of the ships, the weight differential that could exist depending upon payload has bothered me lately. It seems to me the design would need ballasts to compensate for lightweight loads (would you agree or no?), but I'm not sure if the ballasts are built into the design.
Am I off on this line of thought?
It is not actually smaller being larger than ANZAC (127m verse 118m LOA). It is just a lot lighter and this has implications in respect of the vessel structure.From the handful of web pages I've found, it looks like frigates in the 3-4000 ton range generally give Sea State 6 as their max for aviation ops.
The GD LCS is somewhat smaller, so Sea State 5 might not be that bad.
The Future Surface Combatant (FSC) is the RN's vision is for a new purpose designed maritime platform(s) with considerable reach, endurance and utility, primary roles include anti-surface warfare (ASuW), antisubmarine warfare (ASW), anti-air warfare (AAW) and land attack (LA, sometimes referred to as Deep Strike - DS).
Currently it is envisaged that FSC will act either alone or as part of a force, to enable a graduated and enduring contribution to national and multi-national operations conducted from the sea in a multi-threat environment. The composition of its systems and ship’s company will allow rapid re-tasking and re-deployment to meet the less predictable demands of the future operating environment. The size, shape and variety of ships required to deliver the FSC capability will be derived from Assessment Phase studies, four options were under study in mid-2003: a 9500 tonnes trimaran, a Type 45 derivative; a mother/daughter concept; and a family of warships. A variant of the Type 45 design is now (mid-2004) becoming the most likely option for FSC, supplemented by less capable Light Coastal warfare Ships (LCS) perhaps derived from the River Class FOPV design, but other alternatives are still being seriously investigated.
FSC will address identified capability gaps and present the opportunity to introduce new capabilities to the maritime domain. Particular attention is being paid to FSC’s potential contribution to joint and combined operations in support of early entry forces in the littoral battlespace, through both rapid and graduated response, and its operational versatility across the full spectrum of defence missions.
Whilst the pull-through of systems from platforms such as T45 and CV(F) will benefit operational compatibility and maximise the investment already made, there is considerable scope for innovation of design and operation. Hence the potential for a trimaran hull form is being researched, and Integrated Full Electric Propulsion is being de-risked.
The trimaran concept may offer potential benefits in range, economy, survivability and stability. The Trimaran Technology Demonstrator, Research Vessel Triton, conducted joint UK/US trials in 2000-2. And the UK/FR Electric Ship Shore Technology Demonstrator was opened in September 2002. Testing has commenced which will de-risk system integration by demonstrating the system under a variety of scenarios and operating conditions and will be managed by the Electric Ship Programme Office, now also operating under the umbrella of the FBG. The results of both Technology Demonstrators will be considered alongside analysis of monohull research and direct drive technologies before a Main Gate business case is submitted for FSC.
I met some of the UK maritime engineers at DERA involved with the Triton at PACNAV 2000. Contrary to popular perception, the baseline Triton was apparently a refurbed Russian design that DERA acquired from the Russians in the 90's. They also had copies of plans for 60,000 tonne+ STOVL trimaran aircraft carriers (which weren't regarded as viable for a variety of reasons)If you want to consider a trimarian Design for the RAN then the UKs Pre-2004 Future Surface combatants are worth a look.

A pre design to the GD LCS. The ACV Triton currently in service was built as a demonstrator for the FSC trimarian design, and is used by customs as a "prison ship" as some media have dubbed it, in Northern Border protection.
This appears to be where the interest on Trimarians for High speed combat ships started, in the UK of all places! The USN and UK took part in the Studys on the Triton and according to the source a joint report written by senior USN and RN officers in early 2002 on the Triton trials was positively glowing about the results
The Trimarian pictures of Air craft carriers look amusing at present but a posibilitly for the future perhaps as a launching platform for combat aircraft.
Triton is a very different beast to the Austal HSC Ferry hull. It is mild steel and the vessel itself was not particualry fast compared to LCS. It also has a different configuration essentually being a stabalized monohull but with the outriggers located amidships. I have also heard the concept did not live up to expectations and would certainly take GF's word on that. It did provide a lot of data for consideration and was trialed for the US for a while.If you want to consider a trimarian Design for the RAN then the UKs Pre-2004 Future Surface combatants are worth a look.

I still believe the LCS is a good design for Australia. The waters north of Australia are usually calm like you said and the waters around Indonesia would definitely be classed as littoral.The tropical zone would appear to be the areas where a light weight design like the LCS would be most useful.
IIRC there has already been some success in export orders for this OPV class : Trinidad&Tobago ordered a OPV which seems to me almost identical.I like the look of the stretched River Class OPV
To be used up north especially if it could carry a small lightly armed
helo like the squirrell chopper.
Or would this be too small for LCS type of ship?
RIVER CLASS OPV
EXPORT VARIANT
VT has designed an export version of the River Class for deployment in a wide range of operations connected with Exclusive Economic Zone (EEZ) protection, including disaster relief, anti-pollution, firefighting, rescue work and interception.
The flexibility of the OPV design allows an overall increase in length by insertion of a midship section to accommodate additional crew, equipment and facilities. By making special provision to put the ship's propulsion and electrical machinery aft and all the normal crew accommodation in the forward section, the increase in overall length is achieved without a significant re-design.
The baseline export vessel includes a flight deck for land-based small / medium helicopters. The aviation facilities can be enhanced to handle larger helicopters or to provide storage and maintenance facilities for helicopters.
HMS Clyde (P257) is the ninth ship in the Royal Navy to bear the name. She was launched on 14 June 2006 in Portsmouth Naval Base by VT Group shipbuilders in Portsmouth, England and is the fourth vessel of the River class and the first of a lengthened variety with a displacement of 1,850 tonnes and a 30mm Oerlikon KCB gun in place of the 20mm gun fitted to other River class ships.

I have to disagree here, for a number of reasons.I still believe the LCS is a good design for Australia. The waters north of Australia are usually calm like you said and the waters around Indonesia would definitely be classed as littoral.
You dont need a advanced combat ship to patrol the soutern oceans. The whaling ships dont require harpoon missiles to take them out.
I am 100% certain that any threat to Australia will come from the north and we will be fighting in the tropics. The LCS with a lightened AEGIS system would pack all the punch u need. That might prevent that ship from performing other roles due to weight restriction but other LCS ships will not have an AEGIS or anti sub systems fitted. You could even have one or two LCS loaded full of cruise missiles. The enemy wont know what to expect from any individual LCS ship as they could be set up for anti-ship, anti-air or amphig transport.
Different ship for a different role. Clyde is a very offshore PV. O for Oceanic. Excellent range, for a ship of her size, great endurance & superb seakeeping. But not fast.IIRC there has already been some success in export orders for this OPV class : Trinidad&Tobago ordered a OPV which seems to me almost identical.
I think though that this ship is too limited in size and speed to be comparable to a LCS, which remains a FFG. Nowadays FFGs are minimum 3,000t in order to carry the big AAW radars that go with the latest VLSs. A River couldn't carry a Sampson or a Herakles/Empar...
cheers
It is a lot of money for limtied capability in so far as the RAN structure is concnered. LCS could only be procured at the expense of ANZAC hulls, or their replacements, or AWD hulls. It is a poor swap in sor afr as the RAN is concnerned as we have a limited number of hulls for both manning and cost reasons.I still believe the LCS is a good design for Australia. The waters north of Australia are usually calm like you said and the waters around Indonesia would definitely be classed as littoral.
