On a base cost of $225m in 2007, a straight 3% inflation (probably appropriate for a COTS/MOTS design) would give a modern price of around £230m @ 1.4 USD/GBP. 6% inflation (more towards the leading edge) would give a price of c. £300m. Pick your own price point out of that range. I think the Absalons came into service with little more than the guns in place at first
Thanks

It would appear to be at least in the ball park then and not way outside the price range.

The problem with the costs for these programs is that prompted by their local politicians, teams from the UK & US descended on Denmark to find out how on earth they built frigates so cheaply. The answers came back that there was no silver bullet and that once the special conditions around the costings and the reduced build standards were removed, they weren't really any cheaper.

In the days when Think Defence was an active forum, there was a regular poster who was an active MoD naval architect, who commentated on such matters and I remember when he was asked on this topic. I wish I could remember his forum name. APATS maybe? The conversations are still available and I think they would have occurred when discussing the Type 26.

Of course this is a cue for our resident Europeans who bristle every time I mention their lower naval standards compared with the US & UK but whatever. Truth hurts.

Bottom line is that a "proper" 6k ton frigate is going to cost about 600m and a 4k frigate about 400m. Pounds not dollars.

Lots more.

The Absalon is more or less a T26 with the ASW pedigree removed, making it highly unlikely it will come in at a quarter of the cost.

The RN could build it really crap, but whats the point in building a frigate that cant fight?

Would be interesting to see how the Type 26 will fight with just 5-inch gun and CAMM.... :lol:

Sounds good, let's increase the T31 budget by £750m and give RN the 5 ASW frigates @4000t that would really help rebalance the fleet :thumbup:

If you could persuade the RN to take a pretty much single role frigate, I think there would be every chance to build a first class ASW asset with this budget. Spend a lot of the budget on survivability & quietening. Save using diesel electric propulsion for a less than sparking top speed, a much reduced communications fit, and a simple CAMM self defense outfit. No need for anti-ship missiles or a big gun. Obviously would need a HMS & tail. Would also need a Merlin deck & hangar for absolute top performance but maybe a couple of ASROCs and a Wildcat could fill in. Would be a less effective at protecting the carriers than a T26 but would be fine for other escort duties or sub hunting TF's.

4 ISO contaners to be precise.....though on the actual Absalons the space is used as extra spare parts storage.

Quite a bit more i suspect.....the $225M number quoted , was and is pure fantasy.....their actual cost even in 2007 was much higher...400-450 million US dollars , though that does include most of their weaponry. Built in the UK, with a basic fitout, my guess is north of 500 million in todays dollars.
What does the Iver Huitfeldt class offer that the Absalon class doesn't
A more efficient and quieter hull, stronger construction and full naval standards. Though the Absalon is still a much superior GP platform with unmatched flexibility and much better C&C capabilities.
Is the Iver Huitfeldt design much different from Absalon
Yes more than you'd think,.....the internal arrangements are also quite different between the two classes and not just because of the flexdeck.
"The RFI did state that HMG should retain the intellectual property rights of the T31 design, would that be possible if it was heavily based on an existing OMT design?"
Well the RDN have transferred the IP rights of all StanFlex designs to OMT, which as a small'ish design and engineering firm would probably be satisfied with receiving minor royalties so i cant imagine the IP issue to be a major stumbling block.

That works out at about £350m, a lot of ship for the money.

If Babcock/BMT/OMT could combine the flexibility of the Absalon with the improved standards of the Iver Huitfeldt whilst also shrinking the design to put it in 120m, 4500t range it could be an interesting option. The hard part will be keeping it in the £250m to £300m price range.

shark bait wrote:*proven by a Navy that has never been to war.
Its true that the RDN have not seen action since WW2.......which happens to put us in the same club as 99% of the worlds navies.
Only the UK, Israel, Egypt and the US (debateable) have been involved in serious naval combat in the last 50 years......and none of it in this millenium.

Also , the Falklands War was 36 years ago.......one really has to start questioning how much longer the experience and lessons learned from that conflict remains relevant. Almost all western warships built since then incorporate design elements spurred by the RN experience in that war....but no one actually knows if those changes will make a worthwhile difference against modern threats. No modern frigate is going to survive a hit by a 3-5 tonne high supersonic antiship missile or a heavyweight torpedo......regardless of multiple redundancy features, DC improvements and FOST traning.
The Absalon is more or less a T26 with the ASW pedigree removed
I disagree........unlike the T26 , the Absalon was never meant to be a first line surface combatant and they dont have the raw specialized capability that the former does. However it does have some capabilites that that the ASW oriented T26 doesnt.

I used to be among the Absalon class' most ardent critics , regurgitating the "jack of all trades, master of none" drivel that is invariably spouted whenever the class is mentioned. And it IS drivel......i know because they are THE most sought after vessel in the entire RDN, whenever we are asked to contribute to a mission or to complete a task for say NATO. They dont care about our frigates......because regular frigates are a dime a dozen in NATO and Europe......but no other single ship possesses the capabilites of the Absalon class.
Yes they are jack of many trades......but they ARE also masters of some.....they have command and control capabilites second only to those of Carriers and large amphibs or medical facilities superior to anything short of a dedicated hospital ship,...and they have the ability to become quite potent minelayers.
Their troop and cargo carrying capability is not impressive when compared with dedicated transport ships.......but unlike those Absalon can escort itself thanks to a very robust self defence capability....while also not being too shabby in the land attack and antiship department either. They have proven themselfes so useful that if the RDN could go back in time and build the ships again we would have ditched the frigates and built 5 Absalons instead.

Well that is obviously bollocks .....whatever info the US and UK has gotten has been in relation to visits/promotion tours in the respective countries by Absalon/Huitfeldt class vessel. And in the UKs case probably also through Danish ships going through FOST.
The answers came back that there was no silver bullet and that once the special conditions around the costings and the reduced build standards were removed, they weren't really any cheaper.
Not as much cheaper as is officially claimed, but still cheaper......no military yard , most of which cant seem to build anything bigger than a rubber dinghy for less than a billion dollars, would ever match the efficiency of the highly automated OSS yard (or the cheap labour costs of the Baltic yards which built the ship sections/modules ;) ...) .
By the way.... the "reduced building standards" only applies to the Absalon class. Besides ,the cost difference between full military spec build and navalized commercial standards (like Absalons) is much smaller than people think. Its a significant amount of money sure but measured in the tens of millions of dollars, not hundreds.
Of course this is a cue for our resident Europeans who bristle every time I mention their lower naval standards compared with the US & UK but whatever. Truth hurts.
It does......and when someone actually provides any tangible evidence of the supposed superior build standard in anglophone navies i will gladly accept that pain......until then though i will treat the claim as the jingoistic nonsense it most probably is.
I have cross-polled on many US,UK and European warships and i have yet to see any discernable difference in build standard, DC equipment etc.
Bottom line is that a "proper" 6k ton frigate is going to cost about 600m and a 4k frigate about 400m.
Not if its built by BAE....then you need to add a 0 .... :D

Missed that when Ron wrote it, so thanks to MikeKiloPapa for referring to that point.

Am I correct in assuming, Ron, that you were referencing the $100k/ tonne metric for historical builds, so we are talking USD, not GBP there? So approx. £425m for a 6k frigate and £280m for a 4k frigate at current exchange rates.

I remember finding the same articlethat you quoted from, but don't seem to have a link to it. Do you recall the date that it was written, as it would be interesting to attempt an estimate of how much that has increased due to "defence inflation"

That looks like black propaganda pedalled by US as its just too embarrassing, the last US designed warships were the three GD BIW class 15,600 ton Zumwalts, costing ~$4.4 billion each excluding R&D which if included would nearly double the cost, and even then they had to cut capabilities including the volume search S-band radar with its 22 feet high array panels to minimise costs.

HII is one of the two main shipbuilders for USN, Burkes, Ford nuclear carriers, Virginia subs. etc along with GD. HII also build the USCG NSC, Dec. 2016 HII awarded $486 million contract to build its ninth NSC, whereas Eastern Shipbuilding a commercial shipbuilder won the contract for the new USCG OPC at $264.4 million, both contracts exclude GFE. NSC ~4,600T ship v. OPC ~3,600T ship, $105.6 thousand per ton for the HII NCC v $73.4 thousand per ton for the Eastern Shipbuilding OPC, so HII are ~ 44% more expensive than Eastern Shipbuilding. The above is as realistic cost comparison as you can obtain, same contracting agency USCG, same standards and terms and conditions, with the exception that Eastern Shipbuilding priced based on multi year buy whereas HII on one off though ninth of class.

The Danish Navy/MOD/ODT opened their books for the Iver Huitfeldt class ships, but as said it would be too embarrassing and cause to much of face if it was admitted to be true, but it doesn't stop it being reality. Reflected in far east as China launched four 4,000-ton Type 054A guided-missile frigates in 2017, total twenty nine in class and the lead ship of an improved 5,000-ton variant, the Type 054B is expected to be commissioned in 2018 with improved anti-submarine warfare capabilities and IEP, likely feature 32 VLS cells and similar armament to the Type 054A class. If US and UK cannot build warships for sensible costs in ~20 years the Chinese fleet will be larger and with very capable ships.

Thanks for adding some facts. On a news thread it might be "news" that when the build prgrm for the LCSs was decided on, they met the famous "US warships" gold std.
- it v soon became obvious that the std was far from "Gold"
- the std itself has since been changed
- of the new one, the USCG itself has been quoted as aiming for 90% of it, in its own contracting. LCSs (of the Navy) in the format that they have been rolling out - if falling on sideways into the water can be called that - fall short... no one is willing to say by how much ;)

I certainly don't share the "jack of all trades, master of none" drivel spouted by some. The Absalon class is the only example of a general purpose frigate done well, your examples only reinforce that belief.

I would be over the moon if the T31 project delivered 5 Absalon derivatives, but I don't see it happening.

Agree, lessons can be learned from event long ago, technology may have changed but Damage Control is still pretty much how things were done way back before Noah built the ark

I'm very much in favour of the Absalon concept, I fact I prefer it part of the Amphibious warfare ships for the RAN, these ship are perfect for the land attack, Amphibious Ready Element/SOCOMD role being able to perform a number of functions HMAS Choules would struggle in.

Here's an idea, you get some Absalon's and give us Largs Back (Choules) back. :lol:

Absalon is a good concept, for UK use I would tailor it away from amphibious assault, and focus on using its facilities elsewhere. @MikeKiloPapa points out Absalon has excellent command and control facilities, which make it a grate candidate for our contribution to Nato fleets so we can keep the T45 with our carrier group. The expanded boat and aviation facilities make it a great special forces or counter piracy platform. Even taking amphibious warfare out of its role we are still left with a capable flexible platform.

I thought the T23 was. Given the change in the design was pretty much 100% from the original proposals following experience in the Falklands.

I would agree and for me this where a hangar for a Merlin plus UAV and flex deck wins over a mission bay. I think if I was Babcock's I would throw in a extra design for a ship that is 130 m with this layout with a price tag aim of 350 million per ship with a spec of

130 meters
Hangar for up to 2 Merlin's
flex deck capable of holding 40 vehicles or containerized C&C / Medical units / ISO containers and operating up 6 CB-90's
speed 26 knots
armament of 1 5 inch gun 2 x 30mm 9 x ExLS cells = 36 CAMM

Is there any reason why Babcock (or others) can't submit two designs? If I recall the MoD was going to award upto 4 design contracts - not necessarily design contracts to 4 bidding teams

They already have Venator and Arrowhead. If they come up with Absalon and Iver Huitfeldt derivatives as well, they can go for all four :crazy:

Edit - joking aside, it would be nice to see a variety of different interpretations/ proposals put forward, not just 10 different versions of the same generic light frigate
