It should be noted that NIOA Rheinmetall only produce forged shells at Maryborough. Ammunition ‘cases’ effectively. We do explosive fills at Mulwala and we do a bit of primer manufacturing and so forth.Perhaps, but then again perhaps not. The linked article is dated 5 May 2023 and mentions a targeted work force of ~100, whilst also mentioning that the current workforce is only ~60. The fact that current plans involve a 50% increase in the facility's workforce beyond what is currently is suggest quite a few things to me and none which I would consider unexpected or unusual for what I understand is essentially a new facility.
That, coupled with the article also mentioning that the first export orders are now coming out of the facility would suggest to me that the facility is now finally starting to produce enough munitions to have some 'surplus' production capacity, with likely even more available in the future once the facility is fully staffed and running.
When one also takes into account the publicly unknown size and status of the ADF's 155 mm munitions warstocks, one adds an additional layer of demand to determining whether or not such an ordnance factory could have been producing ordnance intended for the Ukraine earlier.
As it stands, I suspect the only way that AusGov could have gotten things further along than they currently are, is if AusGov had started the processes which led to the factory being established even earlier, and this would likely have required that AusGov recognize the need and value in having such a facility sooner than actually happened. IMO it is worth noting that the Rheinmetall NIOA project office to oversee the construction of the new facility in Maryborough QLD opened in Nov 2019, well before the (current) Russian invasion of Ukraine. Given that time would have been required get the munitions factory site selected, or even an agreement to establish a jointly owned facility before the ~two years of construction to build the facility, one would likely be looking at least as far back as 2018 for when things started happening. If nearly a year after the facility was finished and first started operations, the workforce is still only about 60% of planned, then it will likely be another year before the facility is fully staffed. If one wished that the facility was, now, fully staffed and operational, initial planning for the facility would probably need to have started by 2016. I really do not see anyone having been able to predict the current state of things back in 2016.
The major issue, is that Australia doesn’t produce modular charge systems nor fusing systems, especially the valuable PGK guided fuses. We buy that stuff ourselves through FMS.
What we can supply on the “artillery” ammunition front in reality therefore is virtually nothing, unless we can source the remainder of the kit from other suppliers.
The 105mm ammunition in the recent package was different. It was one piece ammunition. They could be supplied and fired (so long as not life expired) almost immediately with no outside support. Not to mention we have no need of them ourselves of course, no longer having anything to fire them from…
