The ANZAC's are very top weight sensitive, as all forces have found.
I was quite amazed at moving off the ESSM and going CAMM and then even more surprised with Canada chosen to do it and going with the CMS330. It seemed odd, because Australia has spent loads on pretty spectacular upgrades, and NZ could dovetail into that very easily if NZ was looking at just keeping them relevant.

There were some reports of issues with the Philippines frigate build, particularly around the combat system and integration.

Yes that what I really don't understand, if they go back to the MK41 for the Anzac replacement isn't it really just a waste of money going with Sea Ceaptor for use for a limited time when there are proven systems in place that use existing infrastructure

No, Sea Ceptor can be used in the Mk-41. LM have already done it and when it is decided to go with tactical length Mk-41 VLS in the KiwiFFX, the Sea Ceptor is quite at home in that and you are the only who has said anything about Sea Ceptor being a temporary thing. In fact the replacement VLS could be the LM ExLS for all we know. Do you have a problem that we chose to go down an independent route rather than blindly follow Australia? The point is that the GOTD chose what they decided was best. Sea Ceptor offered something at the time (2014) that ESSM couldn't and still hasn't got with the much vaunted ESSM Blk II not even released to the fleet yet, which Sea Ceptor is. Also Sea Ceptor is variant of a set of three missiles and one day, heaven forbid, we might just chose to acquire a GBADS and Land Ceptor would fit the bill for the SHORAD, because of the commonality with Sea Ceptor.

And it may well be that ExLS and Mk41 VLS could be on a future RNZN Frigate. Quadpacked Sea Ceptor viz ExLS covering the LAAD end of the spectrum and the Mk41 cells for SM-6 covering anti-air warfare, anti-surface warfare and sea-based terminal ballistic missile defence all in one solution plus ASROC.

Do you have a problem that we chose to go down an independent route rather than blindly follow Australia? The point is that the GOTD chose what they decided was best.
They the RNZN, wanted a weight conscious, fast and more agile handling vessel.

From what I've read those issues are entirely political. A case of the head of the navy insisting on all the systems for the frigates be sourced from one supplier, Thales. So the government fired him and now, as you can see from the equipment list I posted earlier, Thales is conspicuously absent from that list. Here's the list of equipment the navy wanted:

Thales TACTICOS Baseline 2 Combat Management System (CMS)
Thales NS-106 Active Electronically Scanned Array S-band Radar
Thales TS82521 Identification Friend or Foe (IFF) System
Thales STIR Mk 1.2 Fire Control Radar
Thales Bluewatcher Hull Mounted Sonar
Thales Link Y Mk 2 Tactical Data Link
Thales Vigile 100 Electronic Support Measure (ESM)

I find it suspicious that the head of the navy wanted all Thales (kickbacks?) and I find it equally suspicious that Thales is now completely excluded. Political BS.

No its not for me to say you should have gone down a certain route, I understand the reasoning behind the decision. I just find it illogical that you have changed to a different system and that the Anzac replacement may still have MK41, too me it just seems a waste of money changing systems if you are not planning to use it long term in future designs.

What will happen to the new VLS if it not chosen to go on the replacement sit in storage for 50 years? you are spending money on a new VLS when their is a work around to the problem, dead money to me. but its your money not mine.

Mate, this post makes no sense. The selection of Sea Ceptor saved us money, it didn't cost us money. It's cheaper than ESSM, it's lighter than ESSM and you don't need an expensive sensor fit, like CEAFAR, to guide it.

Also, you keep saying things like this: "...if you are not planning to use it long term in future designs". The NZ navy IS planning on using Sea Ceptor in future designs, we've told you that. You seem to take the position that Sea Ceptor and the Mk 41 are mutually exclusive systems and you have to choose one or the other. They're not and you don't. They are perfectly complimentary systems as shown by the RN's T26 weapons fit and LM's development of the ExLS which allows Sea Ceptor to be launched from the Mk41.

I think what we must keep in mind is that the replacement of the frigates is over a decade away and that technology will have moved on from where it is now. Future developments that are only paper projects at this stage and and the existence of them may not even be in the public domain may be available to us when the replacement design is finalised. So basing any thoughts of the replacements completely on current technology would be a mistake.

And it does not require the expense, real estate, weight and cost of Mk41. VLS.

Clusters of the very compact 3 cell ExLS for LAAD via Sea Ceptor complementing the Mk41 cells for larger multi-role weapons like SM-6.

But we know already what are the relevant technical programmes that will be the mature and in use systems in a decade viz EASR & NGSSR, NIFC-CA & Combatss-21 and significantly for us on USN vessels ala FFG(X) whom we and the RAN will be operating alongside - which frankly is where we will need to focus on.

AFAIK money was not really the reason why the Mk 41 VLS was to be pulled from the Kiwi frigates during the upgrade. The main driving issue was topweight. A VLS array appropriate to hold and fire 20 Sea Ceptor missiles takes up less space/weight than the Mk 41 VLS. Now yes, the Mk 41 VLS could have been quad-packed with Sea Ceptor for a total of up to 32 missiles (which is a missile count I would have preferred) but as others have already pointed out here and elsewhere in the past, the ANZAC-class frigates have issues with displacement, and particularly topweight. The RAN was able to adopt one solution (which IIRC required ballasting in the hull and led to less freeboard) but the RNZN could not adopt that same solution without deleting the Mk 15 Phalanx CIWS.

With hindsight, it well have been better if the RNZN had followed the RAN frigate upgrade, but that is life. BTW IMO the primary benefit if the RNZN had followed the RAN upgrade was that it would be a fairly easy transition for the RNZN to acquire one or two ex-RAN FFH's when they start getting replaced by Hunter-class frigates.

The Iver Hutfields were originally built in Lithuania and Estonia. I would imagine if you wanted a overseas build of something like that then Lithuania would be the low cost option. If they Type 31 is based off this design, it still might be possible to have block built cheaper in Lithuania and shipped to the UK for final assembly.

To be honest NZ needs to work out what they want and see if they can join an existing production.
Why would you build blocks in Lithuania and Estonia and assemble them in the UK, the Arrowhead 140 (if it wins) will have blocks built in various UK yards and assembled by Babcock in Rosyth, Rosyth knows what it's doing, this is how CVF was built and how the solid stores ships will also be assembled is the UK govt takes it head out of it's arse and confirms that these are naval vessels and should be built in the UK.

Ngatimozart's suggested plan (and I think it's a brilliant one) would be to employ OMT to design NZ a frigate based on their Iver Huitfeldt design and to have them built in SK.

Hyundai HI have built two Sejong the Great class destroyers for the ROK navy. These are very impressive ships, equipped with Aegis, SPY-1 and Mk 41 VLS. I doubt there would be any issues around technology transfer or Hyundai's ability to build top quality, advanced combat ships.
Having an NZ specific frigate would be very expensive, we have never had a bespoke specific to NZ frigate design before and I doubt the Navy or the Govt would be too keen on having the only examples of said frigate in operation.

To be somewhat pedantic, yes we have. The ANZACs are bespoke NZ frigates by means of cost cutting in their original build with differences in the fitout between the RNZN ships and the RAN ships. Since then the ships have further deviated via upgrades.

The differences in the OMT Ivers that we have suggested are in weapon and sensor fit outs, which are reasonably common in warship builds where different nations build across common hulls. We have not suggested any redesigns of the hull, it's interior spaces, nor have we suggested changing the machinery from CODAD to CODAG or any other form. Hence the cost should still be around the NZ$700 - 850 million range per ship. The poms are trying to build their Type 31 for 250 million quid per ship, but given their recent history in naval shipbuilding, I honestly can't see that happening without significant cost cutting measures, i.e., loss of capability.

No way we should have a build or fit out done in the UK, US, Western Europe, Canada or Australia. It's just too expensive. That's why we are suggesting South Korea, maybe even Japan if the price is right.

If the US decides on a frigate that more or less meets NZ’s needs then tagging on to a US build might be competitive as the build number should be at least 20 for the USN.

On another NZ forum , a user called nighthawknz posted some interesting pics from Australian Maritime Technologies. (I have a feeling they are descended from the local outpost of the German company that build the ANZACs, but haven't confirmed that)

RNZN Frigate System Upgrade |

AMT have played a key design role in both the Platform Systems Upgrade and the current Frigate Systems Upgrade. The piece contains the best computer-generated pictures I have seen of how the Kiwi ANZACs will look post-refit. To this landlubber, the changes are very striking.
I've always wonder why RNZN wouldn't add two pairs of Harpoon ASMs onto the ANZACs as part of the upgrade. This would give it quite a fair bit of Anti-surface capability which RNZN currently lacks.

No one is talking about going to OMT and asking for a Frigate designed from scratch for NZ. OMT produced an evolved design for SEA 5000 based off the F370 Iver, to be OZ built and iirc was to include dual hangers, greater emphasis on ASW than the original F370 Iver and substantially cheaper than the F100 and Type 26 designs. That may fit the bill.

A further OMT refresh of the RAN Iver proposal for the RNZN should not be shatteringly expensive in terms of billing hours (as naval architects they will make their coin in the royalties, design transfer and licensing of the build). With the hull built and foundational machinery installed in a SK contracted superyard like HHI at Ulsan, with the CMS, radar, sensor, asw, weapons fitout (other than RIM-116 dumped for CAMMS) of the FFG(X) from LM and Raytheon as sole source providers and integrators, it may end up being more expensive than a UK built Type 31e Arrowhead but it would be substantially more capable and close to the performance of the FFG(X) and yet less expensive than the USN platform.

If one looks at the possible future candidate frigate platforms for the RNZN from other 5 Eyes Navies (As the apple will likely not fall too far from the tree) we are left with one of the following:

The Canadian future surface combatant, the UK Type 26 and the RAN Hunter Class. Each of those three will be very expensive and would mean that getting a much needed 3rd Frigate would be much more difficult. Or the USN FFG(X) - cheaper than the first three but still not an inconsiderable cost NZ$1.2B, or the Iver based Type 31e Arrowhead, the cheapest and less capable offering - arguably not quite able to cut the mustard in a highly contested Indo-Pacific region post 2030. Finally the 6th alternative, my tweak on NG's proposal above, a refreshed Iver hull fitted with US sourced MTOS systems, sensors, weapons that substantially mirror the FFG(X) capabilities and can like the Hunter Class and FFG(X) connect, distribute and contribute with and for each other.

and I doubt the Navy or the Govt would be too keen on having the only examples of said frigate in operation.
The RNZN Anzac Class are now very different than other MEKO 200 hulls out there - the hull and COTS machinery is the basic bit. It is the CMS, sensors, radars, weapons fit out that are widely different, the bespoke part, the business end. Our post FSU Anzacs are closer to the Halifax Class in that regard than the RAN Anzacs. They seem comfortable with that.

I'd be weary of buying American. Their naval philosophy is at odds with ours. They like specialist vessels with large manning requirements designed to operate as part of a group, and they prioritize speed over endurance/range. Also their ships are very expensive and we'd be locked into using American weapons (no Sea Ceptor?). For comparison, an Arleigh Burke destroyer, built in the USA, costs over US$2 billion, whereas a Sejong the Great destroyer (basically an up-sized Arleigh Burke) built in SK costs US$935 million (FYI, I'm not suggesting those are the ships we're looking at :D, just a price comparison to show the advantage of building in SK).

Anyhoo, we'll see what they come up with for the FFG(X), but I'd be surprised if it worked for NZ, especially cost wise.

A lot of NZers and NZ politicians are tree hugging hippies who think putting offensive weapons on ships is too aggressive for our peace loving nation.

When NZ ordered P-8s there were suggestions in parliament that they not be armed at all. Seriously. Bunch of filthy hippies.

Not sure why there is an assumption that NZ somehow made a bad decision going with the Lockheed Martin Canada solution to upgrade their ANZACs. I think it is a bit insulting to assume the RNZN didn't do its home work when this choice was made. I know the RCN is ecstatic with the performance of the CMS330/Smart-S combination, so there is no reason why the RNZN wouldn't be either. And while there is a good argument to be made that they should have stayed with ESSM for commonality, CAMM is an excellent system, so this is hardly a "bad" decision.

Having exactly the same systems is not necessary to achieve interoperability, The personal training standards and experience cycles are important and so is system communications. What also must be kept in mind is the NZ government's reluctance to spend money on defence, as to get the numbers we either get a simplified outcome, or reduced numbers of fully equipped units. What I was suggesting however was that any ship we replaced the ANZAC's with would unlikely to have been currently in service for a significant period of time as by the time we would be getting our replacements the design would be getting old. Something of the same era as the type 26 would be fine, but something designed over 10 years ago would be starting to look a little old by the time we put it into service in terms of hull design, machinery, noise reduction and crew requirements, etc.
