Questions : Before all this potentially would start, what infrastructure upgrades would have to take place ? Do these have to be done ASAP for a continuous program to be implemented ? What is the current capacity at each location, and what site is best for future expansion should it be a single yard?
If you have a look at some of the links below it will give you an idea of the capabilities (and potential capability growth) of the various shipbuilding, repair, 'module' fabrication capabilities and facilities, etc around the country.
Techport in Adelaide is probably the most obvious choice to be the 'prime' ship/submarine assembly location:
Australia’s premier naval industry hub supporting The Australian Navy AWDs
As you can see from the video the site itself is pretty large and there is a lot of scope for expansion, increased hardstand areas, fabrication sheds, increasing wharf space and increasing the size of the ship lift, for example if the 'ship lift' had been enlarged during the Rudd era (GFC infrastructure money for example), possibly the AOR's could have been built there.
Henderson in WA, there is Austal, builder of all things 'Aluminium', ACPB's, Cape Class for Customs, etc (plus all the 'commercial' shipbuilding work they do too).
Production Facilities :: About Austal :: en :: Austal
The question regarding Austal is will the Government select any further 'aluminium' ships for the Navy? Who knows! But when the Government recently announced the plan for the new class of 'Pacific Patrol Boats' they specified that those ships would be built from 'steel', so that probably excludes Austal.
On the other hand if the replacement for the ACPB's is an OPV based on a 'scaled down' US Navy LCS (or their proposed MRV 80) for example, then Austal would probably be the one to build in aluminium because of their expertise in that area.
There is also BAE at Henderson too, does a lot of maintenance for the fleet based in the West and is also doing the ASMD upgrade on the Anzac Frigates, from memory they didn't do any block work on the AWD's, but I do recall (someone can correct me), that they may have fabricated the main mast for the three AWD's.
And there is also The Australian Marine complex at Henderson with a common user facility too (really don't know enough about this) but I think that that facility BAE and Austal are all located near each other), but here's a link anyway.
Marine Engineering, Marine Services & Shipyard - Australian Marine Complex
And of course there is BAE at Williamstown, currently block work for the AWD's and block work and integration on the LHD's.
In the not too distant past two FFG's and 10 Anzac's were built there too, will we ever see 'Frigate' sized ships built there again? Probably not, but the yard also built the OPV's and IPV's for New Zealand, so it would be reasonable to assume that the yard is also capable of building some or all of the new Pacific Patrol Boats, could be a contender for the proposed OPV's to replace the ACPB's, replacement LCH and future replacement Hydrographic ships too and of course it could also be a 'block' supplier for the Future Frigates too.
And lastly is Forgacs in Newcastle, apart from it's commercial work, is also a block builder for the AWD's, and would be no doubt be capable of performing block work on the Future Frigates too.
<strong>Newcastle</strong> -
In a nutshell, Techport in SA is probably the 'obvious' choice to perform the replacement submarine build, assembly of the Future Frigates (possibly further into the future if the 'ship lift' is expanded, it could also be looked at as a site to eventually build replacements for the 'replacement' AOR's, Choules and LHD 'sized' ships). Williamstown is certainly capable of OPV, PB, LCH, etc, work (as well as block work), Forgacs would also be capable of block work, BAE at Henderson in WA will probably continue on doing maintenance and 'upgrade' work into the future to support the WA based fleet.
And that leave Austal (apart from it's commercial activities), well that will all depend on what any future Navy ships are build from, it it's not steel, then Austal would in the front seat for that type of construction.
So I think that just about covers it! Of course the is the overriding 'politics' of ship building too, no doubt each 'State Government' will be pushing for their 'share' of the work and also at a 'Federal Government' level, depending on which 'seat' you want to 'win' at election time too!!
