What's the model hiding between the Tasman and Hobart classes? The one with what looks like a 76mm and 16VLS cells forward and more VLS cells amidship? An extra amped up Avante or an AWD derivative of the F-110?
If I had to guess, I would say its the Avante Alpha 4000, the F110 is still using the hull form of the F-101/Hobart.
Tasman is a strange choice for a name for Navantia to use, as it has already been assigned to the 3rd Hunter.

Anzac has just been pulled out of the water today to go into Layup. Her long-term future TBD depending on the outcome of the naval review.
Cheers.
I thought she was the lead ship in the next Anzac 'assurance' upgrade whatever its called. Any guess on her fate.

Makes a lot more sense than building 3 more Hobarts. BAE are saying they could build them from ship 4.
The more I think about it the more I like the idea. I can't think why you would really need to change much other than add extra VLS in place of the mission bay. It already comes with CEAFAR2 and CEAMOUNT. Could be the fastest solution to getting extra VLS into the fleet.
The Navantia exhibit at Indo-Pacific 2023 has an interesting design called "Tasman-class corvette". This is based on the Avante 2200 design for Saudi Arabia.
The design is displacing 3,600t and 109.6m-long and 15.35m-wide. It has an anti-air (16 VLS), anti-submarine (MH60, 3 x TT) and anti-surface (12 NSM) capability. Could it be contender for new @Australian_Navy Tier 2 warship?
Either way, the definition of "Corvette" is getting stretched. These are Anzac sized ships.

I find it interesting that Navantia, Civmec and Austal are all involved in this.

First of all I am sure that those companies have been consulted as part of the surface fleet review and the DSR. They would have a pretty good idea about what ship is required

Secondly they appear to be working together rather than in competition. If you want to accelerate a project than bringing together experienced builders such as Navantia, Civmec and Austal might not be a bad idea.

Also not a big vote of confidence in Luerssen from Civmec.

It was changed a few months ago that Warramunga would now be "Ship 1" for the Transcap starting mid-2024. I think that there are 3 options for Anzac: 1. Stays laid up & slots into become Ship 2-3 of Transcap starting late 2025ish. 2. Undergoes a scheduled drydocking & then rejoins the fleet after 6 months or so. 3. Gets decommissioned & stripped for spare parts prior to scrapping. Noting the DSR mentions lack of hulls in water, IMO, I think either 1 or 2 are the more likely options for the moment. If Anzac is decommissioned there realistically wouldn't be a replacement prior to 2030. Cheers.

That is one huge and heavily armed corvettes. I'm impressed that they could squeeze in a ciws and torpedos and 12 nsm. And ceafar. It will be benchmark to beat.


BAE has unveiled a Modified Hunter at Indo Pacific with a 64 Cell VLS module in place of the mission bay, they also lose the towed array sonar. Can also be fitted with the Mk 57 VLS.
That is also a pretty loaded frigate.

I would imagine people might see these and be less excited about Burke's and Hobart's.

TBH I would hope that, if and when HMAS Anzac is decommissioned, she is kept as a museum ship. Perhaps I am being overly nostalgic but she does have a service record for being the first RAN vessel to fire in anger in over three decades when she provided NGFS in 2003 whilst in the Persian Gulf.

There are a number of good reasons to preserve Anzac, the history behind the name, lead ship of what will be if not already the RANs combined longest serving class and having fired in anger in a war like operation. I would like to see her upkeep come out of the Defence budget and done as a joint project between the Australian War Memorial and the Maritime Museum at Darling Harbour in Sydney.

Not sure that it would really be much to beat. A vessel (whether classed as a corvette or a frigate does not matter at this point) that displaces ~3,600t has the same displacement that the ANZAC-class FFH's started out having, and with a length of 109m is possibly ~9m shorter that the FFH, with a beam of 15.3m might be 0.3m broader that current RAN FFH's. This becomes significant in that the ANZAC-class frigates have been found to be very limited in terms of what more can be done to them, with not much remaining in terms of growth margins as well as topweight issues which require careful management. Side note, I believe that the overall displacement of RAN FFH's which have been upgraded is now ~3,800t.

Going with a new class/design which is perhaps slightly smaller, but essentially the same displacement and with a possibly greater weapons loadout, I would naturally wonder what the range/endurance of the design currently is, as well as what margins remain for future growth.

That is also a pretty loaded frigate.

I would imagine people might see these and be less excited about Burke's and Hobart's.
Frankly, if someone wants me to be less excited about more Hobart-class or Hobart II-class vessels, they would really have their work cut out.

If the 'modified' version of the Hunter-class deletes the towed sonar array, particularly if done so in a way that would make it difficult to add back in later, then perhaps having Osborne do a simultaneous/split built. With the towed sonar getting removed, one of the significant ship-mounted ASW sonars is gone, and so to a fair bit of the ASW focus of the Hunter-class. At that point it might make more sense to also not spend all the coin involved in rafting and noise isolation for the more air defence oriented vessels.

I still think that the RAN will need a fair number of ASW frigates given the likely number of subs which will be operated by various powers in the Indo-Pacific region in the coming years.

To be honest unlikely she would be, too many bits will come off her to keep the others going. It also comes down to cost, I don't believe her preservation should come out of already tight defence budget. The whole Otama saga has cost Defence as they were directed to wear the cost of her transport & scrapping here in WA.

to my simplistic brain, losing ASW situational awareness by not equipping a towed sonar is counter intuitive.
I’m thinking it is a minimum required fit for all MCU and anything feasibly tasked with escort duties.

I get the more competitive VLS upgrade, but seriously? ……

For reference the Avante 2200 design which the "Tasman-class" design is based off has a range of around 5,000nmi at cruising speed with an endurance of 21 days while being 5m shorter and 1.3m thinner. Avante 2200 Combatant
Obviously there are heaps of issues I don't know, including price. But if that Navantia corvette has reasonable weaponry, CEAFIR radar, 5,000nm range, and Civmec and Austal are willing to partner with them for construction, it has to at least be in the running for the Tier Two choice.

with the bae proposal…
The sweet spot is surely (multi role) 64 cells, 16 nsm + ASW capabilities + main gun.

over

current
32 mk41 VLS + 8 nsm + asw capabilities + main gun

on the table
96 VLS (96 mk 41) + 16 nsm + main gun (- ASW capabilities)
or
96 VLS (64 mk 41 + 32 mk 57) + 16 nsm (-main gun and - ASW capabilities)
or
128 VLS (128 mk 41) + 16 nsm (-main gun and - ASW capabilities)

It definitely fits pretty well into the original doctrinal role of the Anzacs as regional presence ships with sufficient armament for self defence and basic escort. 5,000nmi cruising and 21 days endurance isn't really ideal for that role though so I'd hope the slight size increase comes with extra fuel and stores.

navantia have a tweener alpha 5000(32 cell), something between the Tasman class(16 VLS) and flight 2 Hobart(looks like the original f100 design with 96 cells prior to navantia takeover), closer to the gibbs and Cox offering

1st pic, behind alpha 5000


Also meko a210


also navantia flight 3

babcock a140


Also… new batch 2 mogami ffm model on show.

From Naval News info on the modifications for the "Hunter-class" guided missile frigate variant.
According to BAE the up-armed, Batch II Hunter, maintains 85% commonality with the existing ships that are under construction at Osborne, South Australia. The most significant difference is the removal of the Thales Sonar 2087 towed array and various other unspecified Anti-Submarine Warfare (ASW) systems.

It would also involve “minor” changes to the ship’s propulsion and power systems to accommodate for the increased top weight of the high-mounted VLS cells.

The proposed modifications would have a “minimal” impact on cost and a “negligible” impact on schedule so long as build of the modified design commenced with Batch II, rather than Batch I ships, Lockhart said.

BAE is also exploring alternative ways to up-arm the frigates through the use of containerised air-defence and surface-to-surface missiles.

Right now, however, a decision has not been made and BAE is simply “offering options” to its customer which is the Australian Department of Defence and RAN. The original Hunter class contract, signed in 2018, always included scope for redesigns between each batch of three ships.

I would be seriously surprised if Australia looked at these 3 designs, they are all brand new designs, how much would Australia be prepared to gamble on an all-new design when we are doing it already with the Hunter.

Yeah - in the rush to salivate, lets not forget that 'Tasman-Class' (and BTW, a stupid name for a RAN vessel. Not Navy and very antagonistic to Maori's along with pretty questionable ethics and leadership) is slightly more advanced than someone sketching a ship in MS Paint. It's 50% heavier than the Saudi ships for starters, meaning significant redesign. It's years away from where Hunter is in the process right now.
