National governments of recient years have shown a reluctance to spend money on capital projects for defence. They will quote a lack of funds, but they are the ones who did the tax cuts. Recently most major projects have dragged on untill the next non national controlled government before funding has become available, so this delay is quite normal.

I would say all those gulf states being struck by missiles and drones right now from Iran and the shipping from there might require some attention
Yes NZ Air defence 2 frigates with around 200 missiles doesn't cut the mustard in modern warfare.
I read that as "Air NZ" for a moment, and my mind froze for a second, haha

These new Sakura class OPV's could be a reasonable contender for future replacement of the current RNZN OPV's Wellington and Otago.
These are impressive vessels regarding their build time schedules, their overall utility and pretty reasonable cost for an OPV.

Just add an ice belt for work in the Southern Ocean and upgrade defensive armament to something like a BAE 40mm MK4 would be my preference.

NZ Government should put in a order for 4 of these, and 4 to 6 Mogami ships along with Australia's order.These new Sakura class OPV's could be a reasonable contender for future replacement of the current RNZN OPV's Wellington and Otago.

A 777 or a 787 fully decked out, ready for war.

If we could get some of these with a possible mogami frigates buy maybe they will be cheaper? Is it the same manufacturer?These new Sakura class OPV's could be a reasonable contender for future replacement of the current RNZN OPV's Wellington and Otago.

It isn't that easy just saying, just add the ice belt. Adding an ice belt can effect C.O.G of the vessel and needs re-engineering etc, which effects how a ship handles different waves and swells... internally it will need to be redesigned to add the extra strength required as it no just the case of using thicker steel.... also adds extra weight which may mean it goes beyond or limit reserve weight percentage for upgrades down the track... ie; like what happened to current OPV's

Ice capable ships really need to be designed as such. For starters, they have frames which are placed closer together than they would be for a similar ship which was not ice capable. Things like the rise to the stern are designed to shed ice, not trap it, propellers and rudders (or their equivalents) are designed so as to limit the possibility of damage by ice. Other underwater fittings, similarly, are designed so as to not be fouled by ice. And that ignores issues of reserve buoyancy and stability. So it is not a simple process of just making the hull thicker.

Yes, to be honest, fair points all, and possibly not doable. It was the Ship builders low unit cost of these OPV's at $66 Million USD that sparked the interest in this idea.

I think its still has merit..That is if the govt truly intended to go ahead with the dedicated SOPV.to compliment Aotearoa who is also ice strengthened and winterized for operation in the antartic conditions.
Two OPV would be used for constabulaty duties on our coast and in the pacific plenty without jaunts down to the sub Antarctic and artic waters. Just hope Govt doesnt buy two of these and just two frigates again.
