IMO the above is not quite accurate wrt Australia's current naval construction dilemmas. Right now, Australia only has a single yard operational which has experience in warship construction and it is currently working on the
Hunter-class FFG's.
SEA 3000 functionally appears to be intended as a crash replacement programme for the decommissioning
ANZAC-class FFH's as well as the establishment of a new naval ship construction centre.
A order for three or more GP frigates built in overseas yards by a yet to be named company of a yet to be decided (or at least announced) class and fitout might be able to cover some of the projected gap between when current FFH's need to be decommissioned and replacement FFG's are ready to be brought into service. The timeframe for this to happen though was tight to begin with and grows tighter as time progresses without announcements being made and especially contracts signed.
In addition to however many GP frigates actually get built for SEA 3000 in overseas yards, a new Australian facility is supposed to be getting established in WA which will then produce the built of the GP frigates for SEA 3000. Right now, it appears that WA GP frigate production is planned to start ahead of lead ship delivery for the
Hunter-class FFG and that there is an expectation that there will be a significant amount of concurrent production and delivery for both SEA 3000 and SEA 5000. IIRC SEA 5000 was originally (when it was still planned for nine hulls) was going to run into the mid/late 2040's with the lead ship getting completed in 2029 and finishing trials ahead of entry into RAN service c. 2031/32. Lead ship delivery has now been pushed back to 2034, ten years after construction on it started, and the overall order book was reduced from nine to six.
Now I forget what all the expectations are about the Australian build run for the SEA 3000 GP frigate, but the impression I have is that some expect lead (Australian) vessel production could start as soon as ~2029 with delivery around or perhaps a year or so after the delivery of the lead
Hunter-class frigate, with future deliveries then running towards the end of the 2040's if there actually are eight Australian-built GP frigates ordered.
This gets into the heart of one of the major problems I have with what current plans appear to be. This major problem as I see it is that, absent a major conflict breaking out which could smash any plans to bits, then there will be two Australian yards looking for work in the mid/late 2040's at a time when the only new construction programmes under way might be the replacement project for the
Hobart-class DDG's and the whatever RAN sub programme is running. Potentially making things worse, as well as increasing competition between the yards, is that at this point in time the oldest active frigates in RAN service should only be about halfway through their expected service lives and therefore not up for replacement.
One of the other major issues, the 'today' issue if one will, is that there really is no way for Australian yards to get new/more/replacement vessels into Australian service before the early 2030's, so if there is a need 'today' or even just within the next few years, none of the plans can address any needs apart from orders placed overseas. Even with the expectation of three imported GP frigates being ordered, this will still take several years to be completed and brought into service assuming no problems occur. If one looks at the current composition and age of the ADF fleet overall, then one is looking at essentially the entire fleet needing replacement over the next 20 years with some elements requiring replacement much sooner than that. Given the number and variety of vessels which should be replaced in that timespan it seems unlikely that Australian yards could meet those needs, even if a second yard was established. In building a second yard, it appears that Australia would need to lean on overseas yards to meet short/near-term production demands, but would then end up with a production overcapacity at a time when the RAN might not need to order anything for a decade or more.
The final issue which currently springs to mind and concerns me is that there seem to be many assumptions about Australia's ability to build a second naval shipyard and then get it operational and delivering quality vessels and how quickly that could be done. If there expectations are overly optimistic, then the current plans (such as they appear to be) could quickly turn to custard and I rather doubt that there would be many viable alternatives by the time issues were recognized. As things stand now, it seems that the plans for Australian-built GP frigates are such that the following need to happen over the next 10-12 years or so;
- Build/modify appropriate physical plant to actually engage in warship production
- Establish and skill a new workforce in naval warship construction
- Cut first steel on the lead Australian-built GP frigate and then have it delivered into RAN service
IMO this sort of timeframe expectation is... optimistic? One needs to remember that first steel was cut on the lead
Hunter-class frigate, after test blocks had already been built, was this year with lead ship delivery now not expected for a decade until 2034. Given that ASC already existed as a facility and had an in place workforce, expecting a new facility which does not even exist yet to get established and assemble a workforce to accomplish all of that and get new production both started and initial deliveries in almost the same amount of time is rather suspect IMO.
Time will tell
