Agree with your sentiments, but not so convinced that the ANZAC replacement will be as combat capable as the ANZACs are (limited as that is). Mapp told me he's a fan of the LCS concept - although he told me that before it bacame apparent the US Navy LCS project is going to be WAY expensive.
I was just being being optimistic
If the NZ Govt wants to join with the Australian Govt and get on board the ANZAC II project in any significant way (also to boost NZ industry - ANZAC I brought hundreds of millions of dollars to the NZ ecomony), then no doubt the Australian Govt would insist that NZ sign up for some vessels, otherwise why should the Australian Govt be so generous next time round?
The Australian Govt will be embarking on a major shipbuilding programme for some 20+ vessels over the next decade and beyond, the NZ Govt would be foolish to not realise the vast opportunties that exist here, thankfully this Govt does seem to, hence some vessel buy in would have to be a pre-requiste, surely.
Granted, if this was a go-er, can NZ justify the larger vessels? I don't think size is really an issue (and Devonport could be modified to accomodate larger vessels), after all a larger vessel would cope with the Southern Ocean better (as from that experience Te Kaha took a hammering that caused hull stress issues), so it would simply mean that NZ would have "fitted for but not with" to reduce some weapon/sensor costs. Presumably the ANZAC II lifespan would be better than that of ANZAC I, which keeps the bean counters happy. Also the extra space could accomodate several govt agency staff (when needed) and trainees (seeing we don't have the luxury of a dedicated training ship) etc. I like the twin hangers, one for a helo and the other for a UAV (or second helo or simply storage on occasions). The RNZN must have UAV technology for enhanced survellience etc.
Granted, as Lucasnz points out there other options though, but I do hope a decision is made quickly and NZ doesn't get bogged down forever looking for alternatives etc.
IMO I don't think the Australian OCV would make a good RNZN ANZAC replacement, as we'd only have the same problems we have now but on a much smaller vessel (if not, more). However I would support OCV's to compliment the current OPV's if that were possible.
I do actually support the current concept of a two (or 3) tier RNZN i.e. a couple or so of combat Frigates for NZ's wider defence interests and committments; a second tier of OPV's for NZ, Southern and Pacific general patrolling and EEZ enforcement (with much reduced combat capabiliites, which is a reality alas), thus freeing up the ANZAC's for serious deployments (and the 3rd tier is that of inshore patrolling of course). So I do hope when the RNZN ANZAC's are up for replacement this model is kept.
I suppose though, if NZ finds the ANZAC II idea unsuitable, perhaps a compromise is to find another vessel be that some sort of LCS/Absalon/F125 type that could be built under licence in Australia (to keep the two Govt's/economy's happy), but I'm a little cautious on this due to the experience with Project Protector (OPV's etc), as we'd be talking about a much smaller production run (2, 3, maybe 4 vessels) hence the economies of scale issues (and costs etc) hence it could cost more than it is worth. Granted NZ could buy direct from the country of origin to reduce costs, but whether this is politically acceptable in this joint ANZ-era I don't know but am somewhat sceptical. Plus the RAN & RNZN wouldn't have some commonality, which in times of "emergencies" (eg Timor 99), could become an issue (I'm thinking of spares & transferable skillsets etc).
So again being the optimist, political pragmatism might mean NZ signs up to ANZAC II (and/or OCV)?
