Now that i have it sorted, i give you 25% of the RAN in dry dock, besides being thankfully Rare it also points out the strategic numbers for our forces, as this docking would require several weeks to finish once out. I believe HMAS Melbourne was in for SM2 upgrade, while the 2 FFH (Parramatta and Anzac (if i recall) were conducting routine maintanence.

I agree with the nuclear option. Not only is the current project mind numbingly expensive for conventional subs, they are at the end of the day, non nuclear submarines. If you really want a long range, high endurance submarine, you get a nuke. The australian government attempting to create a homegrown submarine class in a niche that dosn't really exist any more- if it wasn't for political reasons the long range conventional submarine wouldn't exist- for the precise reason that nuclear subs have a huge advantage over conventional subs simply because they have near infinite fuel and range only really limited by food supplies.
Most modern conventional subs are short range small patrol boats, not the thing the gov is imagining for it's new monumentally expensive boats.
However the off the shelf subs bought from europe are very similar (to exactly the same) to what the other regional countries are buying, which significantly narrows the capability cap between say malaysia and australia.
However several factors have aligned to give us an alternative.
the RAN might be able to purchase Virgina nuclear subs- :cool:
the vigina class sub costs 2.1 billion(as of late 2009) apiece in(in construction) the US, or about 25.2 billion US (roughly).
Now with the current incredible exchange rate you actually end up saving some odd 7 billion dollars.
However the US is much more likely to accept such a sale, considering the current fears of a double dip recession and the potential economic stimulus it would bring.
The Virgina wouldn't have to wait until the mid 2020s to get here and thanks to it's long term upgrade design, it would remain useful for decades.
Asides from the porkbarelling local politics of saving a few shipyards that are costing the nation billions of dollars to keep running, and the ever debatable "nuclear question" you end up getting not only a far more capable boat, but also a far more cheaper price tag.
:cool:

I can tell you point blank without fear or favour that we will not get a nuke.

we will also not get modified Virginias.

'No hope' for fourth destroyer

SOUTH Australia has no chance of winning a contract to build a fourth air warfare destroyer.

Defence Industries Minister Kevin Foley told a Budget Estimates hearing: "I would not hold out for a fourth, to be honest."

In the March election campaign the Government said it was "continuing its efforts to secure ... a fourth AWD to be built at Techport Australia" - despite doubt over a fourth destroyer in a federal Defence White Paper in May last year.

Opposition defence industries spokesman Martin Hamilton-Smith said: "What remains is an idle promise."

In 2007, when the then-Federal Coalition Government chose the modified Navantia design ahead of the more expensive Arleigh Burke, it created an opportunity for a fourth ship to be built.

"I certainly am disposed to seeing a fourth destroyer being built," then Defence Minister Brendan Nelson said. But he said a decision did not have to be made before the end of 2008 - by which stage the Coalition was no longer in government.

Mr Foley told estimates last week that ordering a fourth ship was a matter for the Federal Government but that the global financial crisis meant any cost benefit of a bulk order had been lost. "It will probably cost us more now to get a fourth," he said.

Mr Foley also said the State Government wanted the design work on the next generation of submarines to be conducted in Adelaide but whether to create a new design or modify the Collins-class design or a European design was being debated.

The estimates hearings also noted only a portion of the $8.2 billion AWD work would go to SA - as reported by The Advertiser last November.

Unfort there are some who still thinks its possible - ditto the 3rd LHA.

Its not happening, everyone inside knows it. the desperate and dateless haven't worked it out yet though... :)

we've already had $20bn removed from future budgets.

Well yes- but one can dream :rolleyes:

It does however highlight the problems with both plans- you know something is wrong with the idea when you end up paying more money for inferior boats. Australia really needs to role down the anti-nuclear stigma that prevails in current society. When Clean fusion finally becomes viable the gov or anyone else will have to spend years correcting dozens of sterotypes and preconceptions about it before they can actualy do anything with it.

Both option look bad from my perspective- if the collins is anything to go off by Australian sub building is terrible and simply buying a 214 or a similar vessel would endanger it's regional superiority.

Realistically, the RAN would be neigh impossible due to political influences at home and american cold war mentality- (they view every other country like the australians might view indonesia or malaysia, and well probably be reluctant to impart equaling technology (even if australia would have 12 to about 64) :ban

we could build Virginia sized boats now and run them with some of the newgen conventional engines. The technology is here how. I've been lucky enough to see it when I worked in the US a few years back

Sorry, thats just plain wrong. My first major project was with Collins, I worked on the project at a govt level, worked on it as a contractor for an acoustic signal management developer, and at one stage was a supplier when I had my own company. I provided some of the systems used in the sim programs by the initial design teams in canb.

My last subwarfare conference was in the US a few years back - and I can tell you point blank that the americans regarded it as probably the best conventional long range sub in the world. they were regularly impressed at how these boats came out on top even in partial prosecution events. One of the reasons for leasing Gotland was based on the performance issues they experienced with Collins, they wanted to see how a mini-me verion with AIP would fare under colder conditions (subs behave differently under diff water conditions - and they did have some initial probs with Gotland in prepping it for the east coast of the US)

Realistically, the RAN would be neigh impossible due to political influences at home and american cold war mentality- (they view every other country like the australians might view indonesia or malaysia, and well probably be reluctant to impart equaling technology (even if australia would have 12 to about 64) :ban
you'd be surprised at what the US provides aust with. Aust and the UK are provided access to tech that other NATO parners could but dream about. We have people embedded in facilities that no other nation has access to.
 
...the vigina class sub costs 2.1 billion(as of late 2009) apiece in(in construction) the US, or about 25.2 billion US (roughly)....
I read the full thread before replying so gf has already corrected most of your assumption. That said; your Aus$2.1billion does not include support, servicing and infrastructure. Nukes cost money and - sadly - are difficult to dispose off. I am scared about UK liabilities and wonder if Brazil or India are clear-headed enough to understand the responsibility that they are about to attempt. [Or would they call on our Septic-cousins to bail themselves out...?] :help

I do not know how the DMO is going to save any penny going for nukes instead of conventionals, i think if some American say that they can plug a conventional diesel engine in a Virginia then it will not occur any problem regarding platform suitability, just exactly like the Collins problems, but much bigger...;)
Apart the number of subs, you can have 4 nukes that in a battle versus 10 conventionals, your nukes are lost. From a tv report on the building of the first Virginia, it was told that a nuke when it is moving it cannot heard the passive sonnar well, because of its own noise produced, any conventional sub using rightly its standar batteries, not aip ones, can beat a nuke if this needs to be moving.....etc not strictly.
But the global operational capability given by 4 nukes vs 10 conventionals...

Hopefully...

They're a nice little torpedo, and there is some commonality with the Mk48 ADCAP at a circuitry level.

There's more CPU power on these torpedoes than there is on some navies skimmers combat rooms.. :)

they're no Typhoon killer, but they'll do a hell of a lot of damage. We should never have bought the MU's IMO, it just didn't make sense and cost us in integration terms and in long term logistics. It's been a while since I was able to see the real data behind them, but what I saw a few years back in the US was fairly impressive.
Any chance they'll be put onto AP-3C Orions if MH-60R gets up, in light of the MU-90 debacle? And would this weapon given it's probable compatibility with AP-3C (given it's Mk 46 heritage) and definite integration onto P-8A, be important enough to tip the balance in favour of MH-60R?

I also see that older Mk46 torpedos can be upgraded with what Raytheon calls it's 'low cost' Mk 54 upgrade kit, which may offer some interesting benefits for our existing inventory of Mk 46's...

Yes to all of the above. edit: caveat. with the way that we've ferked up all of our recent helo purchases and their integration due to different systems, any logical assumptions about flow on benefits for the romeos is optimistic. it makes too much sense to get its legs up. :)

How they didn't get up in the first place is beyond me. Seriously, there are times I just shake my head and go WTF?

Shame, real loss of capability. In terms of surface vessels the 4th AWD should have been a priority and decided when we chose the F-100 design.

While I have given up hope of a 4th AWD being build immediately after the 3rd AWD, if ANZAC II is based off the AWD hull, then there is a possibility it could be built in much later, richer times possibly with updated systems.
However, given that a decision will be made not to build it, then it most likely won't ever be built.

Regarding subs, I think we should look at larger ~9000t boats conventionally powered.

You can’t lose capability you never had in the first place. The AWD and the LHD – assuming they work – will totally transform and boost the RAN’s surface combatant and amphibious capabilities. An AWD or LHD will be hugely more capable than a DDG/FFG or LPA/LSH that they replace.

The cases for the 4th AWD and 3rd LHD have a lot more to do with providing a more sustainable fleet. If the extras were ever to have been acquired you would not start to see naval task groups with 4 AWDs or 3 LHDs at sea. But this force structure would enable the RAN to have 3 AWDs and 2 LHDs ready for sea at any one time. Otherwise there are going to be perodic gaps in our capability to sustain the required minimum number of fleet units in these classes.

While I have given up hope of a 4th AWD being build immediately after the 3rd AWD, if ANZAC II is based off the AWD hull, then there is a possibility it could be built in much later, richer times possibly with updated systems.
SEA 5000 does offer a chance for more than just a fourth AEGIS ship for the RAN. But AEGIS is very much the cooperative networking heart of a naval task force capability. If the SEA 5000 future frigate has a high powered phased array radar like AUSPAR it will be similar in radar coverage to the AWD. The SEA 5000 will not need the AEGIS combat system itself if in a task group with an AWD. Such a task group with 1 AWD and 3 SEA 5000s armed with SM6 will be just as capable in anti air warfare as a task group with 4 AWDs.

Regarding subs, I think we should look at larger ~9000t boats conventionally powered.
Thanks to the law of dimensioning returns such a beast would be not that much more capable than a 3,000-4,000 tonne boat and suffer a range of significant drawbacks. The reason you can build ~9,000 tonne submarines is the very high power density offered by nuclear reactors. You just don’t have that density in diesel-electric so would have to fit a huge engine room (6 big diesels) to charge the kind of battery needed for such a huge motor (30 MW) needed to move it.

9K tons is one hell of a big conventional sub. If Aus selects to go down the road of converting a nuclear design to diesel I would of thought they would opt for either a Barracuda or Astute variant. Both capable, very modern and cheaper than a Virginia Class.

Well we will have to sea what animal emerges from sea5000. We may be better off and more attractive politically building these (perhaps more of them). I don't think it will be quiet the same, (what happens if the AEGIS AWD is missioned killed?) but certainly a very strong regional Navy.

Australia is still doing ok with 3 awd 2 LHD on the way. Things could be worse.

Hence why Im suggesting gas turbines. Make the subs longer and less beamy to reduce drag (I think this would be an issue in using nuke designs as a conventionals). Then a conventional turbo or super diesel to run during snorkellings.

BMT did a concept design of a gas turbine sub and found that it actually isn't a submarine. It’s a semi submersible. Turbines require so much air to run compared to a diesel that you can't feed them via a snorkel. Besides what’s the point of all this? With the 2020 tech available for the SEA 1000 you can build a diesel electric with a lot more transit speed and less indiscretion. If battery tech gets so power dense that you need a gas turbine to charge it you will have the capacity for a generator free, all battery ship anyway.

The Collins is an essentially rare boat type. It is the largest conventional submarine in the world, and among a few that attempt to fill the roles of a nuclear hunter killer submarine while running on non-nuclear propulsion and power source. It's a design that no other country in the world uses, or even uses something similar- it spends a lot of cash in maintaince (some 330 million dollars per annum as of 2008) and a lot of time in drydock.
So far the discussion has leaned towards bigger boats, potentially conventional clones of nuclear subs such as the astute. However i fear as the boats get bigger the problems with running them off diesel engines will only mount- even nextgen conventional engines can not be an adequate solution for boats that will be far larger than any other conventional subs in existence.
At the end of the day though the gravest threat to the current plan isn't the boat itself but the people to crew it. the navy faces manpower shortages attempting to crew the 6 subs they have now. unless something changes drastically they'll have no more luck in 15 years time attempting to crew 12.
The other major problem is it depends a lot on technology which may be obsolete by the time it comes into service (not technologically obsolete but rather politically obsolete) replaced by nuclear fusion. While nuclear fusion is unlikely to have the benefits of Diesel-electric, smaller size, less noise and cheaper price (which considering we aren't really utilising this in the first place is largely inconsequential) it will viably replace the nuclear fission reactor by the 2040s or so (if the ITER is anything to judge by)- and since it carries none of the political quagmire that fission has).Australia could use it to power the long range, long endurance, large boats that appear to be what many people here are considering.

I apologise if i overshot myself in my previous post. I have no where near as much experience as some members of this forum.

HMAS Perth cold moved today from the C.U.F to Stirling. Looking very complete from the outside, not so much from the inside.

I was lucky enough to get a full tour of the ship, right up into the new Cupola, I even stuck my head out the hatch on to the AN/SPS 49 deck i.e. 07 DECK!....nice view from up there :eek.

Very weird to walk around a class of ship that has basically been my home for a decade and for it to be so VERY different in many places. The OPS room is incredibly more spacious. It still has the foot print as the old one and has quite a few extra consoles in it, but because the consoles are much much thinner (They used to be very fat because of very large CRT screens) there is SO much more room(It used to be a nightmare trying to navigate around the old one at action station). Seriously the design (which is of a total new layout) looks like something out of the latest Star Trek movie....Flat Screen displays and space age looking consoles everywhere ....with just a few 1980's looking ones to stuff up the illusion!.

On another note I was told the plan was to convert the Chiefs mess to into a SS dining room (it's right next to the galley) and have the Chiefs move into the PO's mess(which is aft as you can go without being in the 3 November Fresh Fish Locker) with the bar being extended into the old PO's dining area.......How am i meant to hide from the Chief now! :hitwall

One area that has not been discussed are the future alternatives/improvements in propulsion systems (not necessarily nuclear).

When one reviews docs like the GAO report on alternatives...
http://www.gao.gov/new.items/d06789r.pdf

Interesting to read about research being done to eliminate things like steam/gas turbines through direct thermal conversion, use superconducting generators to increase power output etc.

Who knows, there may be fuel cell/turbine hybrids (if not already so) that can prove to be much more cost-effective/fuel efficient.

And there's alternative fuels as well eg algae based ship/jet fuels...
