I think it may be helpful to graphically show why I think the Spanish plan to build 3 more Hobarts and continue to build hunters is better than Macus's plan to just build Hobarts. Also the current problem facing the RAN.

I just used an arbitrary metric. VLS. Ships with fewer VLS are typically less capable as combat ships, ships with more VLS are more capable. I think this is a stupid metric. It doesn't account for ASW capability at all. But it is one that ASPI seems to collectively seem focused on. We can do tonnage or other metrics if we wish. I think purely because Marcus doesn't like Hunters, and the Hobart has (slightly) more VLS he pushes that. But even by that metric, its madness and stupid.

Currently our plan is this. Sort of, we will need to take the Anzacs out of service and perform a life extension on them for those going out past ~2035. So even less ships available and less VLS than shown here. The Hunter in-service date is not clear. I stole this from Marcus and his work on building a better Navy faster.. The premier Australian defence thinktank in AU and US.
But even if the hunter first of class moves up 1 or 2 years its doesn't really solve the problem. The RAN dips to ~160 VLS. Hobarts leave service for their extensive upgrade and really we don't recover till the early 2030s. Maybe this work can be done faster. Historical experience with FFGUP indicates its may go even slower. Putting more capability into an already tight existing platform is risky, expensive and time consuming. Have we learned nothing.


1661903257963.png
The Spanish proposal has more ships in service sooner and significantly boosts the RAN VLS capability in total. This also includes the current project to upgrade the existing hunters from 2024-2030. The Spanish believe this is possible. You have the resources of two significant middle powers, Spain has 5 existing ships if they fail to deliver they could back their deal, not with money, but with Ships. Crew generation, recruitment, the Spanish can help there as well.

Marcus's madness. Abandon hunters, down tools, roll the existing blocks into the sea.. This is unlikely to speed up any build, as the team building the hunters well basically breaking all contracts, all existing work and then trying to wrap people around another design. No one seems to indicate this will result in a ship earlier than the existing Hunter build, all for a measly additional 16 VLS, which in the grand scheme of things is nothing. We still have the RAN dipping to 160 VLS for most of the 2020's. The Anzacs are still serving until 2045 or longer. They will need a life extension, which still isn't accounted for in these graphs. We get weaker anti-submarine capability. We get weaker Frigate capability. It would be crazy expensive because we would have to break our existing contracts, we would be paying people to not build things, again.

But most of all, it doesn't provide the RAN with any extra VLS over the Spanish proposal and only ~120 VLS over the current plan. Hardly a dramatic increase in surface capability, and nothing earlier.

We could break this down into more detail.. Say look at continuously deployable capability. So when we go to two Hobarts, that isn't enough to raise train sustain properly. So things fall apart. We become a sometimes navy. We can look at available hulls, or available tonnage of ships. Again loosing the 3rd AWD is huge in terms of the RAN surface capability. Tonnage is probably a better measure.. Two Anzacs have significant patrol capability, but less combat power than a Hobart, but probably more patrol capability. At least tonnage would give a better idea of what is actually available for the RAN.

Given the big conflict or global break down is expected 2027-2030 that period should probably be the main focus. Absolutely anything after that really falls into long term planning. If there is a China and the US as we currently know it. If the global economy survives. If covid, monkey pox and climate change, demographic collapse, social collapse doesn't do us all in earlier. It doesn't match the Spanish 2028 capability until 2038. Far too late.

If we were to look at more destroyers built overseas wouldn't a flight 111 Arleigh Burke destroyer be more value and provide the extra missile numbers looked for? I can appreciate that new training and recruitment would be needed for these ships as well ,

@seaspear

This has been discussed in this thread (and the previous RAN tread) in the past. Happy for you to comment on those responses but asking members of the forum to rehash the same discussion is not popular. Suggest you research the previous discussions.

Flight III AB's would be a powerful addition to the RAN, provided that the RAN can actually get them and have sufficient personnel to crew them. However, where would these destroyers come from? As I understand it, there are two US yards which build these vessels and they are basically occupied with current AB orders (10 approved but not yet laid down, two more planned for but not yet approved) for the USN which could keep them busy for the next decade or more, without any additional orders from the USN.

In short, US yards do not seem to have spare capacity for any export orders to Australia.

Here is a shocking fact, the last major surface combatant built in the US for export was HMAS Darwin in 1984. They have exported designs ie: Perrry and Burke but not finished warships. There ships tend to be to big, expensive and crew heavy for Countries that don't have the ability to build themselves.

There's really two areas that need improvement - 1) the total number of available VLS, and 2) the total number of surface combatants.

Whilst Burkes would add to the VLS count - they'd eat up a significant amount of personnel resources, in turn reducing the potential size of the surface fleet. Given the geography of our region and the ginormous amount of ocean and distance, you're arguably far better off with VLS being better distributed across a larger, more efficiently crewed fleet.

The gap in the present plan is the space between our Tier One combatants (Hobart & Hunter) and our Tier Three combatants (Arafura). Something filling the Tier Two space between Hobart/Hunter and Arafura would go a long way in bolstering the size and capability of the fleet, along with greatly increasing our ability to provide constant distributed presence throughout the expansive region.

Such vessels would also act as the primary platforms for deploying autonomous capabilities for MCM and Undersea Surveillance, thus replacing the need for the (up to) twelve specialist, single-role vessels. That's the direction Japan, the US and UK are going and given our significantly lower personal resources (population), and the need to bolster our surface fleet, you'd think it'd be an obvious direction for us to take too.

It's all about the best way of utilising finite resources (personnel, industrial capacity and money) to derive maximum capability and strategic effect - along with the ability to effortlessly adapt to the needs and priorities of an ever-changing strategic environment.

I think counting VLS is a flawed metric.

Yes, as at today the 3 x DDG and 8 x FFH, have a total count of 208 VLS.

But that doesn’t tell the true story.

The 8 x FFH have 8 VLS each (total 64), but each cell has ‘quad’ pack ESSM, which gives you a total of 256 missiles.

The 3 x DDG have 48 VLS each (total 144), the load out can be ‘sliced and diced’ in many ways, for example, each ship:

* 40 x SM-2 + 8 x 4 ESSM (32) = 72 missiles x 3 DDG = 216 missiles.

Or

* 32 x SM-2 + 16 x 4 ESSM (64) = 96 missiles x 3 DDG = 288 missiles.


The total number of missiles varies significantly, it could be 472 missiles, or 544 missiles, or even more if the DDGs carry more ESSM in place of SM-2.

Do we actually have 544 missiles (SM-2 and ESSM) in stock?


A while ago I heard some suggestions of adding an addition 8 cell VLS to the FFH (but we know they have a well reported ‘top weight’ problem), but if a solution was found, those 8 x 8 VLS could add another 256 ESSM.


Lastly, the Navantia proposal ... hmmm...

Sounds good on the surface, but I seriously doubt they can deliver what their PR department is suggesting they can do, I don’t believe it.

One - Is it at all possible to complete and have in the water three additional Hobart Class vessels by 2030?
Two - If possible, would Navy actually consider this proposal.
From Defence Connect
Navantia Australia proposes AWD boost for RAN
This comment from Chief of Navy, Vice Admiral Michael Noonan seems to sum up the expectation going forward.

“I currently have in place a very robust surface combat transition plan, which does not take into account any contemplation of additional air warfare destroyers,”

I am open to the Idea if it is at all possible from a manufacturing point of view and it is also acceptable to Navy.
Build them overseas if you have to.
Delay any upgrade on the existing Hobarts for down the track, keeping all three in service with additional Hobarts adding to the Fleets numbers as we later transition to the Hunter Class.
Bigger fleet, much sooner with more capability.
Sounds like a win all round. Whats not to like

So we wait for the defence review to see if this concept gets any traction.

But that would mean another six months at a minimum to sign a contract and time is not our friend.
2023 is a few months away and then its seven years to 2030.

Hmmmmmmm............................I want to like this idea but I think they will go with the existing surface combat transition plan.

Hopefully I'm wrong

So looks like we are back to mounting a five in gun on the Arafura Class with a F35B on its flight deck !!!!!!!!!! :rolleyes:

Two further Astute classes still under final construction.
What is the gap between completion of the last Astute Class and commencement of construction of the next generation UK SSN?

Also, the AB is , ultimately, a ship designed in the 1980's. It's evolved and upgraded a lot, but it's still an old design arguably on it's last legs for upgrading.

Fairly sure they're moving straight to the Dreadnaught Boomer after the last Astute

Dreadnought Class | Royal Navy (mod.uk)
According to its own website work has already begun on the Dreadnoughts, The Agamemnon should not be far away from being launched, I suspect Dreadnought will be laid down in the next 12 months taking Agamemnon's place on the blocks. Actually when you look at it with the age of the Vanguards, the build time of RN SSNs, about 11-12 years for the Astutes, their sheer size and the requirement for the Dreadnought to be in service by the early 30s, they are cutting it fine.

3 destroyers built and in the water in 8 years ? Seriously ? Which shipyard on the planet is currently capable of doing that (and don't say the PLAN) ? I think CN's statement was pretty clear so can we move on from this "coulda woulda shoulda" discussion already ?

Pretty stumped we are choosing the Astutes to train on considering the US defence fellow coming out and publicaly stating "AUS sailors should start training on US subs asap" and we use US combat systems. Unless its nuclear sys ops training. Interesting.

Thoughts?

Nuclear systems training would be very comprehensive so this is likely the first priority. Probably significant similarities on reactor operation as the US technology has been shared with the UK.

I would imagine the fundamentals including basics in nuclear physics and alike would be cross comparable between both training regimes. Difference s might arise between the different reactors but physics is physics or so I learnt at school. I watched earlier the commissioning ceremony of HMS Anson earlier (
). It seems perhaps from the remarks by the British PM that our Deputy PM Marles was in attendance after his tour of BAE Systems facilities.

Don't forget we will also undergo USN training and serve on a USN SSN also. So it looks as though we are working on two avenues to have RAN submariners gain experience on SSNs which makes sense.

From my reading of recent articles the RAN is proceeding with training of submarine officers (presumably the engineers) at the USN naval nuclear propulsion school, at a low rate, say 2-3 officers per year. This training is intensive and in a very well equipped facility. At this rate a few dozen RAN officer engineers will be trained by say 2035. In the USN system there needs to be a nuclear trained engineering officer on duty in an SSN at all times. So each boat neeeds 3 or 4. Hence this number would be sufficient to provide the engineer officers in 8 RAN SSNs. These officers would be useful in RAN or RN or USN SSNs.

Whereas it looks like the RAN is committing to larger scale crew training with the RN in Astutes.

In todays ABC news a commentary by a U.S admiral that building extra submarines in U.S and U.K shipyards" could be to big a burden"
US admiral issues blunt warning on building Australian submarines in overstretched shipyards - ABC News
" If you were going to add additional submarines to our industrial base that would be detrimental for us."

So Australian politicians are detrimental to the US Navy. Good to know.

Pretty damming, then adding the UK is in the same situation seals it. No early submarines coming from anywhere. No magic dream boats. What unsurprising news. Not sure what Dutton was alluding to or he was talking to given this. Maybe he can explain. Maybe he had seen under siege and thought he could steal a few submarines and a battleship from the US with some nuclear weapons without them knowing..

Collins LOTE, goes ahead, Collins come out of the water, Hobarts come out of the water for their upgrade, Anzacs need life extension to make 2045 and upgrade, they come out of the water... The new OPV doesn't have a gun, it needs to come out to have a 25mm gun fitted...

Super dooper.
