Because as opposed to any other type or class of ship, it’s what we have.
But it doesn't fit.
If we ever envisaged fitting these systems we would have to build the 90m OPV, which could have embarked these systems, without giving up the flight deck and completely compromising the entire mission of the OPV while also not performing any other mission adquiately. We even further modified the Arafura's to get the RHIB capability that was inherent in the 90m OPV, which further compromised the weapons capability of the platform.
Would you rather have 11x missile armed ships and 12x virtually unarmed ships or 23x missile armed ships, knowing full well of course that 12x of them may well be armed to a degree but are still well short of the capability you’d choose if not politically hamstrung?
But what is capable? We can fit NSM onto a bushmaster, probably onto a LARC-V, but is it capable of using it? We can fit phalanx to a truck, but putting that truck onto a lcm isn't making it a CIWS on a naval platform. Carrying any of these would be for decorative purposes only. We might as well fit them with mock ups.
At the moment the OPV's have no weapon larger than a .50 cal. We hope, we can fit them with a 25mm gun.
It beyond political limitations. We are talking about impossible due to engineering and physics. Probably more than that, time, money and engineering capability to mad max the OPV's into some sort of shitty naval technical with a C-dome container launcher on the back isn't possible either.
It would in fact be more doable to refit a Sydney ferry or the spirt of Tasmania with the weapon systems than the OPV. They could completely give up their normal role as ferries so all of the space, power, weight etc could go to supporting these systems.
The fact that RAN (and ADF more broadly) has to resort to such measures to get the basic building blocks of capability approved by our idiotic political class is a national disgrace and I hope it doesn’t cost us dearly.
I don't see it as this. Rudd announce the 20 OCV back in 2009. Sea1180 was a valid project that wasn't high profile enough to get the politcians messing in it. They, now liberal government tended for 12 OPVs. I don't see a whole bunch of political interference. If anyone is to blame it would appear to be defence.
If anyone is to blame for the OPV's, it is squarely defence. Defences fingerprints are all over it, as the audit office shows.
Of all the ships offered, we chose the least combat capable. A ship that Brunei got because the corvettes they originally ordered were too capable and sold to Indonesia for half price brand new, by Lurrsen.

Lurrsen/Damen/Fassmer all have more capable OPV and small ship platforms. 90m is a much more suitable size for OPV, and all three have capable ships at that size. Most of them are the OPV design, enlarged to take on these weapons systems and the things required for them to operate. So power, weight, space, crew etc.
When I say more capable, 8-16 VLS, 4-8 NSM, 76mm main gun, CIWS (some for
and aft), a hanger, towed array, bow sonar, 2 x 20-30mm guns RWS, etc. Its not just bolting on the weapon system, its integrating it, it having crew to maintain and operate it, its sensors to make it useful, it power to run it. Then with the realisation of that we have less than 10 years, we could start refitting these ships over the next ~5 years with the systems and continue to build them with them integrated from the begining.
Currently we are building them with nothing more than a machine gun.
C-Dome with nothing else is a terrible idea. I would rather nothing fitted and the OPV be able to do their primary patrol mission and use Camcopters from the helo deck. At least they would have some situational awareness.
If we want something more capable, then dispose of the Arafuras. Don't change them into shitty naval technicals, with weapon systems grafted onto helo pads that were never designed for weapons. Its a waste of time money and crew.
Take that crew and put them on a fully armed OPV that has more firepower than an Anzac.
