The 2012 model was certain a major change from the 2011 model, but the new 2013 model appears to be more of a refinement of the 2012 model rather than a major change to the overall design concept.
Absolutely, the 2011 releases were pretty much just CGI about what the design
could look like rather than what it realistically will. One of the more obvious updates during 2012 was the addition of SCOT-5, a SATCOM system, IIRC.
Looking at the three models, some of the big changes from the 2011 model and the two latest models appears to be:
* Removal of the mission bay and doors at the stern.
* Removal of the smaller hanger door for a UAV
* Enclosing the openings for the RHIB's
* Removal of the Harpoon canisters (has a Harpoon capability been deleted??)
With regards to Harpoon It's certainly not something that has been talked about on releases about the ship, which leads us either to the investment of an air launched AShM (NSM would do nicely), a VL missile which can fit in the silos (preferably LRASM) or not having the capability full stop. The latter would be ridiculous. Personally I believe we will ditch Harpoon, the current block (1C IIRC) isn't particularly modern and there isn't a drive to modernise them in any way AFAIK .
The other interesting point you made (in another post) was to do with the VLS position changes forward of the bridge between the 2012 and the 2013 models.
Looking at the 2012 model it clearly shows a total of 48 VLS tubes ahead of the bridge (24 appear to strike length), the photo of the new 2013 model (not taken high enough) it's not clear from the photo if it is the same configuration or as you also suggested, but it does appear to be a reduction in the 24 strike length to 16).
I suppose that has been offset by also having the 24 VLS tubes at the back of the funnel. I won't go into the other changes you have also mentioned such as what appears to be a much taller mast, etc.
Ah, the 24 aft of the funnel are individual dedicated canisters for CAMM. Due to their nature of being cold launched missiles it makes them very easy to locate. These aren't proper VLS, these are canisters designed for CAMM and CAMM only. The only proper VLS are those fore of the bridge.
It used to be 24 strike length, the model looks more like 16. Hopefully FFBNW space for more if that's the case. The foreward missile setup used to be 24 strike length VLS + 24 CAMM canisters, giving our frigate 48 missiles for point defence. The 48 canisters are still about.
For a potential Australian frigate, the foreward VLS space would need to be expanded.
The thing that particularly interests me (once the overall design is settled) is what will an 'Australianised' version of the T26 possibly look like?
Just my personal opinion, but I could imagine an RAN version of the T26 might have:
* The same 5" gun as on the AWD's.
* A 48 cell strike length Mk41 VLS system ahead of the bridge, same as the AWD's (is the T26 design flexible enough or capable to allow for that?). I would imagine that an RAN version would want to allow for the possible inclusion of SM-2 or SM-6, the proposed Tomahawk missiles and possibly in the future the LRASM-A from the MK41's too.
* Replacement of the RN version's 24 VLS cells behind the funnel with an 8 or 16 cell MK41 VLS for quad pack ESSM
* CEFAR and CEAMOUNT on the mast (as is being applied to the upgraded ANZAC's)
* 2 x quad pack Harpoon canisters (it appears that in the latest two models of the T26 the design doesn't appear to include Harpoon), is there space for Harpoon in the current design?
I don't know if there is space put aside for Harpoon, it's not one of the capabilities that has been talked about, so I can't really comment about the official line. But Harpoon can be designed into some reasonably compact spaces. There have been models released in the past with Harpoon and I would be REALLY surprised if that consideration hasn't been made with BAE.
BAE 5in gun should be fine, aft silos probably not compatible with Mk41. Only reason CAMM is there is because it's cold launch, but not sure what the space under it is used for so maybe?
CEAFAR & CEAMOUNT is fine, BAE in the past have teamed up with CEA and put out that the technology is compatible with the mast with a couple of mock up drawings.
The other thing is the size of the flight deck, I can't imagine that the RAN would be looking at operating CH-47's off their version (if selected for the Future Frigate), would it matter? Probably not, but would it be possible if not needed, to extend the length of the hangar to allow for 2 MH-60R's and possibly a UAV too.
With regards to UAVs, shouldn't be any trouble. The Type 26 is designed with a 'mission space' in lieu of a mission bay, with the goal being UUV/USV/UAV storage. Think things like Scan Eagle/Fire Scount.
Can't see why the design couldn't be stretched to make it possible, it probably could be done. Looking at the model, you can see where the davits are for RHIBs is forward of where the hangar is unlike on a Type 45. Depending on the internal layout, the 'mission space' is probably either side of the hangar, but if it isn't and it's further forward closer to the davits then the hangar could be huge.
One of those things which we won't properly know about until 2015.
Yes, all of the above is speculation on my part of what an RAN version might look like, but as you said 8 other nations are looking at the T26, so I suppose there must certainly be a number of different versions and configurations being created by the designers.
Interested in your thoughts.
Cheers
Should also emphasise i'm no shipwright, this is all from my perspective. The design as is isn't great for Aus requirements, but that's why we've signed agreements about collaboration on frigates. All of the RAN's requirements will be taken into account, either in tweaking the base design for things like hanger space or space for VLS or in the production of an Aus variant. We are very keen to export these ships, the modular nature of the ship has been well published, so I expect we're very keen to be as accommodating as possible in the design
