My 2 cents worth .... I also agree that for NZ, UAV technology, especially for maritime survellience in particular, but also overland survellience has to happen in due course, and that NZ Defence should be provided the funding prompt smart by the Govt to investigate these trends with partner nations (and no doubt NZ is investigating, but at an uninformed guess, we're probably not up there with Australia for example at the high end, more like at the lower end etc).
Another area of importance is the ship launched UAV's that Australia has been trialling with its Armidale patrol boats (and for inclusion in their future OCV's. FF's and AWD's etc). Think how much such technology would enhance NZ's current IPV's, OPV's and Frigates etc.
As for armed UCAV technologies, it makes sense to also investigate the options (but no doubt, NZ will tread carefully thanks to these legal aspects that Mr C. raises).
We have to become more involved, but realistically to what level? Moahunter suggests we get in bed with the US but Twickiwi has pointed out NZ would have to make realistic contributions to curry favour. Sure I am for that but knowing the way changes of NZ Govt's can flip-flop on defence issues, I wonder how reliable the US Govt would see NZ? Especially when they can do all the testing with the likes of Australia - totally reliable ally, have plenty of airspace, most of it far, far away from people/spys/peaceniks etc, and have had a history of Govt-Govt defence investment. So I don't wish to sound as if I'm pooring cold water on Moahunter, for I'm interested in his viewpoint along with anyone else, but Canada/US and Australian/US relations are in a different league to NZ/US relations (certainly on the mend, but not there yet, and probably could never reach that same level as Can/Aus because of NZ politics, economics and economies of scale etc).
The other area I am not clear about (I have heard others with more authority comment, usually not at DT though) is whether the US, the leaders in UAV technologies, would necesarily want to either share or hand over such hi-tech technologies and information to other nations especially a country like NZ? It also seems we would be plugged into a US network system - what if NZ unfortunately suffers another ANZUS type relationship breakdown in the future and the plug is pulled? We'd be stuffed. And what's to stop others hacking in and taking control etc?
Don't get me wrong, it would make sense for there to at least be some sort of Pacific UAV survellience system involving the US, Australia and NZ etc. But how far beyond that is another question (in fact why would the US want someone like NZ being involved in these technologies beyond NZ's sphere of international surveillence and SAR etc, as they can simply do it themselves etc)?
My real point is, sure lets get involved more and lets take it to a higher level where possible, but don't put all our eggs in one basket.
For that reason I do support NZ reinstating its modest air combat force, either at a lower level for pure NZDF training purposes, or ideally at the level we did have eg maritime strike, CAS and land/sea interdiction. (And the other thing is, I don't see Air Forces around the world ditching their manned aircraft purely for unmanned aircraft - wasn't that supposed to have happenned supposedly in the 1960's? And didn't former PM Helen Clark say that one reason why NZ was ditching its ACF was because supposedly other nations would be doing so too? It didn't seem to happen, especially in the A/P region, and I wouldn't count the RAF cutbacks as being the same thing seeing they still have credible ACF's and are investing into both Typhoon and F35 etc. So please excuse me thinking I've heard this all before)!
For similar reasons I would support the continuation of NZ's P-3 long range maritime patrol force (and hopefully another long range replacement eg P-8), but supplementing them with long range maritime UAV's. An excellent force multiplier as Twickiwi says. Because to ditch the P-3's (or not go with the P-8) would have a similar devastating effect as ditching the ACF. Basically the entire P-3 air and ground crews would be made redundant and so much institutional knowledge would be lost, especially if we put all of our eggs into the maritime UAV basket and for some unforeseen reason it didn't work out as intended. Like the ACF it would be very hard to recreate after the fact.
So let's do it, but wisely and not be blinded by the marketing pitch that it will solve all our problems and needs etc. Sure, maybe post 2025 etc things will be there, but that's still another 16 years away.
On an ironical note, if the Greens and the like are so afraid of UAV technologies, maybe they'd support NZ reinstating a manned ACF then
