It was never due to start the FSU until this quarter but there was a delay.
What really could be an issue is that there is at present a geo-strategic deterioration that is happening at the worst time for the RNZN viz New Zealand.
Effectively one just Anzac for the next 3 years and no upgraded Anzac that can achieve an operational level of capability until 2021.
I do think it is well time a proper fright of stone cold dread proportions is felt by our political class over defence - it might not be too far off.
A major part of the problem is many defence items have high total costs, as well as long service lives. Therefore, barring a drastic change in situation, whatever gets selected, in whatever quantity is selected, that is basically it for a generation. Contributing to the issue is how long it can take to get kit into service.
As has been mentioned previously in this thread, if things goes smoothly, the RNZN will be down to a max of one frigate available for service from later this year until 2021, as the badly needed upgrade programme gets underway.
If there are any unexpected service demands, or issues with completing the upgrade, that could push the date back further.
IMO that should signal to the NZDF and gov't that it would be a good idea to start bringing forward plans for the replacement of the ANZAC-class frigate. Unfortunately that would also likely mean that the NZDF has multiple, major capital/capability replacement programmes running concurrently.
I would also hope that the NZDF starts, now or in the very near future, plans to increase both the size of the future frigate force, and proper planning to ensure adequate numbers of the needed range of skills to crew the frigates and other RNZN vessels.
IIRC one of the issues which was looming after the contracts for the Project Protector fleet were signed, but before delivery, was that the RNZN was likely to struggle to provide enough crews for the then extant vessels as well as the incoming ones.
