The RAN didn’t have the people to crew the Kidds, FFGs and the Anzac class. Something has to give and FFGs 1-4 is the obvious short straw. End of life of these ships was 2008-12 and even Darwin would have been 22 years old if it decommissioned to crew Anzac 8. FFGs 5, 6 would last to 2020 and could always be kept in service with SM1 decommissioned like the USN does its FFGs. They could serve as northern border patrol frigates in the meantime leaving the Kidds and Anzacs the warier roles. 14 DDGs and FFHs is the best option for the RAN in this timeframe.



The issue is height not the surface area footprint. Mk 41 strike length are about 1/3 higher than Mk 26. You might be able to fit in tactical length VLS to the aft section if you really need more than 61 missiles. It may fire rockets but it isn’t rocket science replacing Mk 26 with Mk 41 would be relatively straight forward especially as the RAN could accept the tactical length launchers not needing to shoot TLAM or VLA.
With 61-64 strike length cells forward you could still have VLA and TLAM leaving the 64 tactical length cells aft full of ESSM and SM-2, a very formidable load out.

Not getting the Kidds was dumb and probably caused many of the crewing issues experienced from the late 90s.

But the ship could not support that kind of weight. The 61 cell strike length VLS consumed all the missile launcher weight margin available to the ship. The same weight could be used for 96 (actually 104) tactical length VLS. With the huge benefit of being split 48 forward and 48 aft meaning no need for all the ballasting that the Spruance class had to carry when converted into strike destroyers. Also since the launchers fit into deck height of the replaced Mk 26 there is no need to do a major repackage of the ship like in fitting the strike length VLS forward. Further if you were to fit TLAM into the Kidd class you would need to add the Tomahawk targeting capability. In Spruance class this went into the space used for the horizontal rack ASROC magazine. This space was not available on Kidd class as their ASROCs were carried vertically in the Mk 26 magazine and the room was needed for the enhanced AAW systems.

VLA fits into tactical length VLS so you don’t need the bigger launchers to carry them. The only reason to have strike length is as the name suggests to carry TLAM. Later the Blk III SM-2 adds a booster for extended range and needs strike length cells. But without a systems update the Kidd could only carry the SM-2 Blk II in RAN service.

There was no requirement for TLAM in the RAN in the 1990s and the Kidd class did not have the ASW systems like upgraded Spurance class to justify the extended range of VLA. Though integrating VLA into the fleet wouldn’t be a bad idea if you could use the Seahawk for targeting (like the old Sea King, Ikara data link).

Not getting the Kidds was dumb and probably caused many of the crewing issues experienced from the late 90s.
If we brought the Kidds then it probably would have terminated the AWD program before conception (Sarah Conner style). So the Kidd class would probably have to serve into the 2020s. What we needed was a DDG/FFG replacement program launched so as to provide lead ship in commission in 2008. Which is the timing to begin replacing the FFGs at the end of their life and to dovetail into the end of the Anzac program.

This program could have been given to ADI to manage and Tenix left to build 12 OPCs to replace the Fremantles on their existing production line. But the Howard Govt. was cutting defence so was not to be.

You can’t fit Mk 41 VLS to the aft end of a Spruance though one up front would provide 61-64 cells which is more than enough. You could buy 4 Spruance strike destroyers alongside the Kidds to provide the 61 cell Mk 41 VLS and hulk them for spares for the rest of the ship (minus combat system). Space aft from removing the GMLS could be used for almost anything.
For the early Tico's (and I suppose the Spru-cans since none of them got any sort of VLS aft) there were machinery spaces in the way of a strike length VLS and to the USN at the time anything short of strike length wasn't worth it.

But I was under the understanding that the Spruance class was at the end of their life hence they were all disposed or sold to a dockside Navy. Ticonderoga class cruisers after the first five had an extensive hull redesign which has enabled them to serve on.
The Spruances were at a point where it was either SLEP or scrap.
The DoD under Rummy and company choose to get rid of them and very quickly sink or scrap all but one example, instead of the traditional reserve fleet status. This was done to provide no easy backup solution to LCS and DDG-1000.
As for the block 0 Tico's. They were technological orphans compared to all the other Tico's and most of them spent their last decade of service chasing drug runners in the Caribbean and visiting South America.
The USN did the math and upgrading them with VLS, hangars that could take SH-60, updated CMS, CEC, and a whole host of structural reinforcement wasn't worth it, so the USN convinced Congress to just buy more Flight IIA Burkes instead which were more capable ships all around.

Here’s a left field idea for the RAN in the late 1990s to go along with the Kidds. Acquire these ships along with the seven Spruance class that did not receive the strike destroyer modification and were decommissioned at the same time as the Kidds. Upgrade and commission the four Kidds and four Spruances with the remaining three used as spare parts hulks. Decommission the first four FFGs and use components of these ships to upgrade the Kidds and Spruances. Their helicopter equipment can go onto the Kidds to make them Seahawk compatible and their radars onto the Spruances. Fit all eight with 96 tactical length Mk 41 VLS and upgrade the Spruance fire control system to support SM2/ESSM like the FFG Upgrade. You would then have a fleet of eight highly capable destroyers half customised to AAW but still highly capable ASW and the other half vice versa. The Anzac class can be left in their initial patrol frigate configuration and the two Australian built FFGs sold overseas.

You would have eight destroyers each with 64 SM2, 64 ESSM, 16 VLA, 8 Harpoon and two each of 127mm Mk 45, Phalanx CIWS and LWT launchers. The AAW ships would have the NTU combat system, SQS-53 HMS and a single Seahawk. The ASW ships would have the FFG Upgrade combat system with SPS-49 VSR, supported by TAS TIR and SPQ-9 HSR and two ICWI directors. For ASW they would retain the excellent upgraded Spruance systems of the SQS-53 HMS and TACTASS towed array and a two Seahawk capability.

Would certainly be far more capable than four upgraded FFGs and the ASMD upgrade of the Anzacs. CEA radars could be used to upgrade the Kidd/Spruance class further.

Collins class are back.........

I read in the latest edition of Navy News that HMAS Dechaineaux, Sheean and Waller are back at sea, and were exercising with HMAS Perth.
Can't remember the last time I read about more than one submarine being available and at sea.
Good news.

The Ticos and the Kidds each had different hull structural tolerances than the Spruance class to carry extra weight. Kidds more so (consumed by their NTU systems, Mk 26 GMLS and required masts) and the Ticos more so than more so (AEGIS).

Mk 41 VLS was originally designed around the tactical length for the then generation of missiles: SM2, VL Harpoon, VLA. But then as part of the Lehmann’s Tomahawkisation of the US Navy they were lengthened to carry the strike weapon. SM2 later received the Blk III with the new booster to leverage the extra length. But if you don’t have Tomahawks or predate BMD and the potential of extended air defence missiles (SM6) then strike length is a lot of extra weight and a whole deck level you don’t need.

Even for a hypothetical USN Spruance or Kidd upgrade tactical length launchers can provide a lot of capability. With 96 VLS that could mean a load out of 64 SM2 Blk II, 64 ESSM and 16 VLA. Which is a pretty fearsome AAW outfit with enough shots for 4-8 major engagements. If you had a weapon like LASM you could have a bombardment destroyer loadout with 48 LASM and still enough AAW weapons for 32 SM2 Blk II and 64 ESSM (same number of AAW weapons as a F100 destroyer). Not the same clout as a strike destroyer with 61 TLAM but a far more balanced fleet unit and able to respond far quicker with mass fires to any targeting requirement within 350 km.

The Spanish unemployment rate has just reached 27%
Is it time to order a Spanish built refueller, along with Spanish built blocks for the 4th AWD, or will the decisions be announced a little closer to September 14.

Trying to compile a list of RAN subs that have deployed to Malaysian and Singapore waters over the years. Here's what I've got so far -

1. HMAS Oxley in Bersatu Padu 1972

2. HMAS Ovens in Starfish 1992

3. HMAS Ottoma in Flying Fish 1997 [HMS Trafalgar also participated].

4. HMAS Dechaineux in 2011. Her participation was cancelled after encountering technical problems whilst in Singapore.

5. HMAS Collins in Bersama Shield 2012.

6. HMAS Dechaineux in Bersama Shield 2013.

Why do you want to take the work away from Australian yards it would have to be very cheap for the government to even consider this. If we order a Spanish oiler all that will achieve for them is the royalties for the design, building would and should take precedence here. Before HMAS Sirius was thought up we were supposed to get a purpose built ship most likely the Berlin class in (2009 to replace HMAS Westralia and HMAS Success 2015) it’s not like we don’t have the capacity to build one, if the Spanish would like us to place an order for them to build it’s the 3rd LHD or even a SCS variant using the LHD hull but spending that sort of money is not on the governments priority list RAN’s might be, but not Gillard and Co.


Wonder if they would put in an unsolicited bid in for SPS Cantabria?

The 4th AWD would be locally built, after building the first 3 here, the 4th should be a straight forward exercise and bridge between the AWD and the Anzac replacements. Part of the reason for the 4th awd is to maintain building capability.

However, a 3rd LHD or/and an oiler would be the logical choice if Australia was looking to err, assist in the spanish issues. A 3rd Hull would I imagine be built a very low cost. I don't see it being a SCS variant, too risky and not what we need. Australian fit out would also benefit Australian sustainable building capability. However it comes down to timing, the gap between Sea4000 and Sea5000 programs.

I don't think the RAN will just buy SPS Cantabria, but it will be deployed here until one is possibly built (hull in Spain, minor fit out in Australia).

So you could have say a 4th AWD, a 3rd LHD, an oiler (or 2 and no 3rd LHD) being built to bridge 4000 to 5000 build programs. However, there is no real desperate need to help Spain out, and there is no 4th AWD yet, so if a government wanted to keep spending down none of these may eventuate.

But the submarine replacements and the frigate replacements seem to overlap, I would assume an interleave build, eg one frigate, one sub etc.?

I'm no expert on project management but your proposal would surely create efficiency problems with the facility/personnel/management team etc.
Nothing works better than a full on production run a la Anzacs, Armidales and previous USN building programmes( I'll have to consider the LCS's).
As far as building the AOR's, a few considerations apply, the first of which is steel production. Would we be able to supply the amount of product for a 1 or 2 large ship build, probably 100+ tonnes per week, given our much neutered industry?

I would like to see the submarines being built early than now planned, so that by the time Collins is to be decommissioned, we would have a fleet of 8, and the fleet further added to after the Collins are all decommissioned, as is now planned for all the extra subs. They will have to find another builder for the Anzac replacements, maybe Newcastle or Williamstown.

Williamstown is does not have a building way big enough for 7000 tonne ships. Same deal in Newcastle really and the facilities they have do get tied up in maintenance work.


Cockatoo Island was big enough but it is shut down and never likely to reopen.


Finally there is the skills issue. a fragmented or "spike of work" does not help. I am a big fan of batch building. Four at a time of each MFU and ..... perhaps the submarines. To this end SWUP in the Collins and the building batches of submarines between other platforms would keep the workforce in a number of yards (well perhaps two) busy with ship building or block construction. It would also solve issue with replacement of a whole class of ship at one time and the added issue of carrying over obsolete systems over a long production run.......... aka the ANZAC frigate.

Finally if scheduled properly (in other words the politicians don't stuff it up) it could be managed in a way that there is alway a block in production.

i.e. 4 AWD, followed by
4 ANZAC II, followed by (if practical)
4 New SM, followed by
4 mod ANZAC II (block 2), followed by
4 mod new SM (block 2)........... and so forth

Minister Mike Kelly has stated his desire to get Navantia to Techport.
If there was a collaboration with them, would we have the capacity to build the AOR's there after the synchrolift was extended or is there a capacity there to develop the site and build on a way and launch traditionally?

Defence Materiel Minister Mike Kelly wants to invite ship designers like Navantia to South Australia's Techport precinct | adelaidenow
If it came off it would be great as it would allow domestic build of large support ships. Just not sure if Navantia would be keen on building outside Spain as the optics would be bad. Still building somewhere is better than go broke.


The optimist in me could see a swap in the form of blocks for No4 AWD (if that ever happens) and another LHD hull (if that ever happens .... appears remote) as a salve.

In respect to his idea that this would allow us to build for the region .......... cannot see that happening (and we have been down this path before) given cost of production.

As per the front page of the Australian this morning, stand by for the announcement on the fourth AWD in the next couple of weeks (along with more Super Hornets and an order for the Hawkei armoured 4WD)

Thanks for the heads up on the article, just read it now.

The 4th AWD would be a great move. The Superhornets I'm no longer a fan of though to be honest. Guess we will wait and see how it pans out.

I would think that the 4th AWD is a certainty ... but the cost might be cutting back the scale and timing of the ANZAC replacement.

While the AWD, LHD and submarines get a lot of press time the Anzac replacement hardly gets a mention.
