Ah thanks for reminding me. I had seen Xavier's report earlier last week and didn't connect the dots, so went back and had another look. It can replenish solids not liquids, so I stand corrected. In the video below Xavier's report on the BMT ELLIDA vessel starts at 8 minutes.I agree with your comments on the ELLIDA vessel, I was about to post a similar article when I spotted yours. I watched the presentation from Navy News with Xavier and the presenter said that the vessel has accommodation for 350 extras.
WRT Ellida... not a bad concept but the devil's in the detail, which there doesn't seem to be a lot of. Here's my reckoning... with Tankers and LPDs the key to meeting outputs is bulk... the capacity to deliver bulk fuel & supplies on the one hand and on the other the capacity to deploy sufficient numbers (in bulk) of vehicles. Storage on board of either requires on it's own a considerable percentage of the hull capacity.Now that the Babcock OMT Arrowhead 140 is to be the RN Type 31 FFG, there is talk on the RN thread about NZ acquiring it. It would make quite a bit of sense, especially now that Babcock acknowledge that most of the export will be sales of the design, systems and engineering expertise, rather than actual ships, because most customers will want the ships built in their own yards - see my post here. So if we went down the Type 31 path, we could have it built in South Korean yards, for example, and fitted out to NZ specs and with the pommy price roughly being £250M, about NZ$500M per ship, well within our price range. They are a GP FFG and from what I read in the 2019DCP, and associated documentation, the NZG is expecting the ANZAC frigate replacements to be well over NZ$1 billion per ship. Save the RN has some good details on the Type 31 including an illustration of the proposed layout.

We do have a requirement for a 3rd frigate, sooner rather than later, and on the surface the Type 31 does meet most of our requirements. Of course, we'd have to change a few things, like mount a 5 in gun up forward etc., but that's not a deal breaker. It's most definitely worth have a very close look at.
Another vessel of interest is the newly released BMT concept design ELLIDA Amphibious / Tanker / Multi-Role Auxiliary Vessel. Being 195 m in length, it has a welldock, 2 spot flightdeck, internal vehicle and stowage decks, weather deck stowage and additional accommodation able to undertake landing craft & boat operations, multi-spot aviation and replenishment at sea. It's probably a bit large but could be scaled down to say 135 - 150 m length (Canterbury is 131 m), and it offers significant capability. From the illustrations, it looks like it has a fuel replenishment capability, so would be a back up or Aotearoa when she is unavailable and if it was ice strengthened and winterised to the same level as Aotearoa, could undertake the McMurdo runs the years that Aotearoa doesn't. Again this vessel could be built in a South Korean yard, for example and it has the potential to offer capabilities that would meet the enhanced sealift vessel requirements. It also has very good HADR potential. One definitely worth keeping an eye on.
They've dropped the e from Type 31 recently. No, I don't think we'd go with an Indonesian build, preferring mature and well established shipyards - less risky. That'd be my take on it anyway.Would NZ ever consider an Indonesian build? The Indonesians were after 2 or 3 of this type. Possibly with a UK fitout. I feel the Koreans would like to sell you a Korean design.
For NZ type 31e
The low crewing would mean you could basically crew 3 ships with what you have now. They should be pretty cheap to operate, I would imagine three would cost similar amounts to the two Anzacs currently.
- 5" /54 mk45 mod 4 upgrade
- 2 x Torpedo launchers
- Some sort of solid state radar (UK/AU/CA would sell you something)
- CMS330(?) Just changed to it, but would be unique to NZ ships.
- I wonder if you would keep a 40mm up front, and a Phalanx out back, or go the twin 40mm route. Old Phalanx units could probably be sold onto Australia.
- 24 Camm be enough? I presume so.
What size limitations? It's 6,000 tonnes.Still think the T31 is a risky choice given the limitations on upgrading due to its size. Given the increasing tensions in the Asia pacific region which will likely get worse in the decades to come, future proofing with a larger design seems reasonable. NZ at least can see how well this ship delivers on its promises as no purchase will occur any time soon. Also, three versions of the T26 will be underway as well. A $500 million ship today might not seem like a bargain 15 years from now.
The other significant advantage of the T26 is the ASW capability and 'quiet hull'. Noting the increased number of submarines being aquired by regional powers ASW cannot be undersold. The T31 (if it follows the parent design) will not have rafted machinery and the stated fit is just adequate. True, remotely operated vessels can be carried that would give it an area towed array capacity which would increase effectiveness ... but the T26 can do this and has an immensely capable mulit static ASW suite.I was under the impression it was considerably smaller, my bad. Still, the T26 has an extra 11 meters in length and the beam has an extra meter. Whether this extra volume is available for expanded kit might not be the case of course. I guess the final sum for 5 ships will be an important factor as to the success of this project as will be the actual T26 project for comparison.
I agree about the rafting of the machinery but unlike Australia, NZ is looking at a GP frigate rather than a specialised variant. The build can include the machinery rafting, low band hull and a towed array sonar, plus a good ASuW and AAW capability. With that, we would still have a good quality frigate for a cost that is somewhat less than the T26. Interestingly the USN & RN speak highly of both the Iver Huitfeldt and Absalon classes, so I wouldn't be overly concerned that it doesn't meet with some Australians approval. IF it is chosen by the NZG, it'll be serving in the RNZN to carry out NZG policy objectives, not in the RAN.The other significant advantage of the T26 is the ASW capability and 'quiet hull'.

It really comes down to the percieved threat. The UK can work with this as they have 8 T26 on order, however, if the T31 (or similar cheaper unit) was purchased ny NZ as the sole frigate type then that will be their ASW capability. It would not be possible to retrofit the machinery rafting (it can be fitted at build as there is space and weight for it) and a significant systems upgrade to improve ASW capability will not be easy. At the end of the day it comes down to the RNZN and NZ government setting their priorities but once they have they are pretty well stuck with it.....
Decision made now will have to consider likely changes to the eternal environment.
Yes I agree, you would have a good frigate with those modifications but you would get it at a greatly increased price, rafting machinery is an hideously expensive exercise with huge ramifications to ship services, pipework et al.I agree about the rafting of the machinery but unlike Australia, NZ is looking at a GP frigate rather than a specialised variant.

The dock at DNB is the largest in NZ, from memory, but there has been a push by industry for a large dock to be established somewhere within NZ. Picton was one suggested location. I don't think that DNB has any room for further expansion of the dock. The dock is leased by Babcock from the RNZN. The current preference appears to be for a floating dock.Yes I agree, you would have a good frigate with those modifications but you would get it at a greatly increased price, rafting machinery is an hideously expensive exercise with huge ramifications to ship services, pipework et al.
Size is also an issue for NZ. I would presume that you would wish to keep all sustainment work, including dockings in house so that would entail either the modification to Devonport or purchase of a floating dock or is there an alternative which the T31 equipped RNZN could use?

Rafting being expensive would be par for course and whilst we would prefer it for obvious reasons, the pollies don't think like we do unfortunately. We'll just have to wait and see what happens. There are a minimum of 4 elections between now and 2030, and a lot can and will happen between now and then.
And right on cue, in today's online NZ Herald: Devonport dry dock eyed by Government for possible shift to Northport
Just in case you don't have a premium subscription here's the core text:
The Government is investigating shifting the Devonport dry dock to Whangarei waters as part of its considerations on relocating the Ports of Auckland operations to Northland.
Associate Finance and Regional Economic Development Minister Shane Jones said the Government had allocated several million dollars to Northport for a commercial analysis on the costs of creating a drydock near Whangarei.
"We are keen to see if there is some scope for relocation of the dry dock."
The ship repair and maintenance dock at the Devonport Naval Base is owned by the Ministry of Defence.
Jones said the dry dock was a valuable facility "but no longer fit for purpose".
A Defence spokesman has confirmed Jones' understanding that the dry dock cannot service naval vessel the HMNZS Canterbury or the new KiwiRail ferries. It will not be able to service the new ship the HMNZS Aotearoa when it arrives in New Zealand in April. All these vessels are too big for the dry dock.
The facility has been leased to Babcock Australasia, part of the global aerospace and defence company Babcock, or its legacy companies, since 1994.
No-one from Northport, a deep water commercial port at Marsden Point near Whangarei, would comment on anything about the commercial study, citing a non-disclosure agreement imposed by the Government.
Northport is 50 per cent owned by the listed Port of Tauranga, and 50 per cent by Marsden Maritime. The Ports of Auckland has a nearly 20 per cent stake in Marsden Maritime, which is majority-owned by the Northland Regional Council.
Port of Tauranga chief executive Mark Cairns declined to comment, citing a confidentiality agreement.
The total Devonport Naval Base is 22 hectares and has a land value of $134.7 million, said CoreLogic. The dry dock is about one third of the total area.
Babcock, which is believed to be open to working at Northport, has been approached for comment.
The dry dock, the official name of which is the Calliope Graving Dock, named for its location at the foot of Calliope Point, was the largest dock in the Southern Hemisphere when it opened in 1888.
Defence records say the Navy purchased it in 1986. The last modifications to the facility were in 1996 to accommodate ANZAC-class frigates.
>>> the article then goes off on another tangent...
A quick perusal of Nelson’s facilities and industrial capacity doesn’t indicate that it would be suitable for a major fleet base.But Nelson port recently won an deal to expand its port to up to 230 metres,which gives us another option too, if someone can post he link?
I would agree that Whangarei would be better suited than Nelson. Plenty of deep water near the oil refinery and heaps of room onshore for facilities expansion. Nelson is hemmed in and would require reclamation works.A quick perusal of Nelson’s facilities and industrial capacity doesn’t indicate that it would be suitable for a major fleet base.
Surely Northport is more suitable.

May only need rafting/insulation on one set of engines. I think they will get reasonable capability out of it if it is selected.I agree about the rafting of the machinery but unlike Australia, NZ is looking at a GP frigate rather than a specialised variant.

Awww.. not even sometimes? I think the Anzac program leaves a bitter taste for many a Kiwi. But I do think its much more likely that the NZ replacement frigates will be operating in and around the south pacific region, while Australia's "frigates" are more likely to go into the South China Sea, the Gulf, and other heavily contested spaces, in the back yard of peer adversaries.IF it is chosen by the NZG, it'll be serving in the RNZN to carry out NZG policy objectives, not in the RAN.
