Thanks for your thoughts. I have to respectfully disagree. I think CAMM is a significantly better than a sea sparrow, which in many ways is pretty redundant AFAIK
From what I have read, as a sea sparrow needs to be 'walked' to its target by ship radar, and current ANZAC radars/fire control only have a single channel, only one can be fired at once. I may be wrong here, but this is what I have read in the past. On the other hand several CAMMS can be launched in succession. This is better for saturation attacks.
And as you have mentioned, there is a range improvement.
For one, the Mk 41 VLS can pack 4 times as many missiles. 8 vs 32.
I don't know much about how CAMM stacks up vs ESSM, apart from the range figures that are publicly available. In my mind, this make ESSM significantly better than both.
Cheers.
If there is sufficient topweight margin for CAMM to be quad-packed, then CAMM does provide quite a bit more than the Sea Sparrow currently does. In terms of capability on an individual missile basis... Not as much. The CAMM is ~99kg vs. ~231kg for Sea Sparrow, but both have comparable ranges of ~25km for CAMM and ~19km for Sea Sparrow. The active radar homing of CAMM does mean that an illuminator is not required and that a channel limitation is less of a guidance issue, but that also means the missile itself needs to establish a lock on the target to my understanding. Given the smaller size of the onboard radar vs. the ship's radar, I could that being a potential issue. Also there is the potential of warhead, the Sea Sparrow warhead is 40kg, and I suspect the CAMM warhead is about 15kg, based off the warhead sizes for the RAM and Sea Wolf, which are the closest missiles in the CAMM weight class. Depending on what the target is, such a small warhead which is not HTK might not be enough.
Many of the other advantages that CAMM has (not requiring an exhaust for launch, etc) IMO do not matter, since the Mk 41 VLS was already designed to allow missiles requiring such to launch. Now if the RNZN were to completely rip out the Mk 41 and go with a dedicated CAMM VLS as Volkodav mentioned, the story could be somewhat different.
This is the question - I wonder what sensor/CMS updates have been selected to go with that. CAMM itself isn't particularly fussy - anything that can crunch some numbers down a data link to give it a reasonable steer will get it going in the right direction but I wonder if there's other BAE work involved, that might bear on Type 26 selection? Because if you really wanted to keep the price down, you'd do the same as the RN and pull some kit through the Anzacs.
They could stick on the CEAFAR set from the Australian updates (skip the TI's of course) and that'd be a significant upgrade, or could we be about to see the first ARTISAN export order? Certainly, either would fit into a Type 26.
In terms of range for CAMM, I've been told that short of any airborne assets being present, 20km is the start of the engagement cycle against a sea skimmer in any event, so as a self defence system, there's not much in it.
Obviously if we're talking engaging mid altitude aircraft, then that's a different kettle of fish.
You could certainly do local area defence with CAMM - it's got double the reach of RAM or SeaWolf - it's not an AWD fit missile but it's got reach enough to cover a convoy or a task force. And yes, of course, I'd sooner be sitting behind a Daring or a Hobart with Aster or SM6
Part of my issue is that CAMM itself has basically the same reach as what is already in service. The real advantage is the potential for them to be quad-packed, thus allowing more potential shots.
As for engagement range, not so such that only 20km is correct. Depending on a few factors (like radar and/or illuminator antenna height, inbound missile altitude, and ability to detect said missile) a missile could be picked up and engaged by shipboard sensors 30-40km out. I used a potential engagement vs. a Storm Shadow missile, with a ship antennae/illuminator height of 10m, and the Storm Shadow altitude of 30m, and that left me with a radar horizon of 35km, where for the first ~10km, the ship could 'see' the missile coming, but had to wait to take action.
Now if the use of offboard sensors/systems were included, and/or the target was at higher altitude, that potential engagement range could grow even further.
There is also the potential for the software integration into the existing FFH combat data systems to be a problem. Not sure how much of an issue it will be, but from what I understand, most of the work to make the CAMM so modular was on the software side, to reduce the amount of dedicated hardware required to deploy them.
From what I can see the Sea Ceptor has an ability to attack small surface craft as well as its anti aircraft / missile capability. I don't think ESSM can do that. It also doesn't need a specific radar and targeting system, theoretically integrating with 3rd party equipment. It also has a soft launch capability and has a minimum range of 1km with a max range exceeding 25km so it's far better than what we have. So we'll see.

ESSM has been tested for use against smallcraft, though not sure what the minimum engagement range is with one. Most of my other concerns I have already covered above.
The one concern I have not already mentioned relates to potential wartime usage. Had the RNZN gone with ESSM, then if reloads were required during a Pacific Ocean conflict NZ could potentially draw upon RAN, RCN, JMSDF or USN stocks to reload.
