I was trying to categories them based on designed roles, which, as seen by this little debate we are having, is not exactly easy. 😉
We have CVS/Sea Control, ASW, Amphibious. However some of these designs can do more then one of these, or do them with different levels of capability.
That is exactly it. And the ratios of those roles are defined by what else in the fleet and what the fleet is meant to do.;)
Compare with the proposals for LHA-7/8 (Powerpoint slide).
USMC amphib briefing dated 21-05-2008 with references to LHA-7/8 (Powerpoint). Suggests that LHA-8 onwards may reinstate the well deck. A pity about the spelling & grammar. 🙁
True, something that shifts things back again. I guess they really need to justifie the AAAV!
The problem being that once again even though the ships look the same, Ocean only operates rotary winged aircraft while LHA-6 will operate both fixed and rotary winged assets
Exactly, hence the extreme difficulty in categorising and comparing.;)
However the primary role of vertical assualt gives at least a vague doctrinal similarity.
What I see when I compare these ships is how varied they are, & how hard to fit into neat categories.
Precisely my point.;)
I maintain however that the Invincible class have morphed into attack carriers and now has little resemblence to the ASW ships originally concieved.
As a very very rough comparison I would put LHA-6 in the same category as HMS Ocean, despite the obvious size difference! Neither has a dock but both are intended to operateheavy helos. You could roughly compare the CAS role of Aapches on Ocean to that of F-35’s on the LHA-6 and of Chinooks to the MV-22. Very rough however.
I wonder how much the inclusion of well deck on the San Antonio class allowed the removal od one from the LHA-6?
I put Hyuga and Invincible together as they were both designed primarily as ASW carriers, primarily with helicopters (Hyuga completely).
Invincible was not with Dokdo, you may have been referring to Cavour which i wasn’t sure about placing as it is supposed to act as either a carrier or LPH.
I was under the impression that Ocean was an invincible with a slightly different superstructure and with the Internal Passageway’s widened and built to commercial standards
Ocean is a very different ship beyond the hull form, for starters she uses an entirely diesel propulsion set compared to the all gas turbine plant of the Invincibles.
Invincible may have been designed as an ASW ship but the class has been transformed into attack carriers and their current role has little resemblance to the Hyuga.
Dokdo has a well deck, Cavour does not, big difference. Not tomention the full up V/SYOL capabilities of Cavour versus the at best (and possibly non-existant) capabilities of the Dokdo.
And of course the U.S governments have never ever supported ‘undesireable regimes’ :rolleyes::rolleyes::rolleyes:
cheers baz
I never said they did not, you are fabricating comments to argue against and you now owe me an apology.:mad:
If you had bothered to read all the posts properly you would have recognised that I was pointing out that the UK supports dogy regimes aswell as the US.

If you wanted to categorise those ships into their designed roles, then Invincible and Ocean would go with the Hyuga class. Wasp, Juan Carlos 1, Tarawa, Mistral, Cavour and Dokdo go together. PdA, GG and Viraat would go together.
Invincible and Hyuga were both designed as ASW carriers, Ocean is basicly an Invincible with Diesel engines and some modifications to the Internal passageways so it still fits into the same category. The second lot are all LHD’s except for Cavour which is a hybrid LPH/STOVL carrier. The final ships were all designed and built as dedicated aircraft carriers, GG and PdA were built to the US Sea Control carrier concept, which basicly makes them a more fixed wing orientated variant of the Invincible class concept, while Viraat/Hermes was originally designed with an Axial deck similar to all the other examples, though it was modified to an angled deck while under construction, she is the closest example to a “modern” CTOL aircraft carrier out of all of these, simply because she used to be one.
The conversion of the ex-Foch into a STOVL carrier with ex-USMC Harriers would be an interesting concept, as would its conversion into a STOBAR carrier with Mig-29K. With the age of its current airwing, they wont have much choice if they want to keep the carrier running much into the future (you can only upgrade 1950’s and 1960’s airframes so much).
No, to start with just becuase Invincible and Ocean share the same basic hull design it does not make them the same type of vessel, they are intended to do very differen things.
And why would you put a Dokdo in the same category as an Invincible? The latter is an attack carrier with a secondary (at best) amphbious capability whilst the former is a near dedicated amphibious ship. The Hyuga on the other hand is a an ASW helciopter cruiser, all very different vessels.
Just becuase it has a large flat deck it does not make it the same as another ship with a large flat deck.
Yes, we can see that.
Have you ever read a car magazine comparison. Maybe they are irrelevant, after all some people own snowmobiles also? Read the first couple of paragraphs. You may be incapable of understanding the relevance of direct comparison but please don’t assume others cannot take them for what they are and keep a sense of perspective when reading them.
The difference with cars is that there inumerable different models purchased by an incredible number of people usually with very similar needs. A completely useless and foolish comparison with navies.
I don’t know why I’m bothering to respond to your arrogant drivel but I will take mild amusement in pointing out that you made some incorrect statements about the Invincible class. You state “The British ships have very little amphibious capability because they were never meant to have it” when in fact Invincible class was designed to accommodate 500 troops (some sources quote 907 troops). And the other British ship in the frame, HMS Hermes, was in fact a “commando carrier” during the Falklands but shifted role when it was decided that she was too precious too act as such and her landing craft (still carried by INS Viraat) and troops where transferred to other ships. -hence my comment in the text about assault carrier (LPH etc) and light fleet carrier requiring similar designs but implying diverging operational considerations. The specialism versus flexibility conundrum; no doubt you have a view but please don’t share it.
And your point is what, these are still roles and needs defined by the wider fleet structure itself a product of the unique environment in which it is moulded. You have just pointed out the absurdity of your own methodology.
As for my comment regarding the Cavour being a better “harrier carrier” than Wasp or USS America (based on what we know of the latter) that means exactly what it says. It is. You may be of the view that USMC doesn’t need a carrier what with the USN’s CTOL carriers but I gather many in the USMC aviator community disagree and USS America is seen by some as a USMC carrier for F-35Bs via the back-door. Either way if you are carrying jump-jets (Harriers of F-35Bs) why not add a ski jump so that they can carry more and go further??? And if you don’t need a well deck (USS America won’t have one apparently) why go taller-and-narrower (like a LPD) when you could go shorter-and-wider making more flight deck for both jump-jet and rotor ops????
Basically if you’re a jump-jet jock in the USMC (or any navy) then the Cavour is better than a LPD.
Comments that show your lack of understanding, contrary to what USMC fighter pilots might think LHA-6 is not an aircraft carrier for them, it is a vessel for vertical assault. So you have still created a conclusion that is completely useless and then responded with a post that suggests a problem with anger control.
Got to laff at that one, F104 project and america back handing half the politicians of europe to sell them an aircaft that could not fly in anything approaching bad weather:D
Pointless post, the reference was not to corruption but about relations with undesirable regimes.

I never said we should have a comparison or debate without context. Man your one of the best and more knowledgeable members of this forum. But, somebody has put a ber under your saddle and its not me…………maybe next time?;)
Deal.;) Again I would like to applaud the talent of the original author on the quality of his work here, but it is only a reference piece.
Seems this thread is working pretty well: lots of interesting responses. Some of which are much more informative than stating -without any elaboration – that my question – whatever you take it to be – is somhow answered by Absalon and F125.
You are right, you have yet to elaborate your question, when you tell us what it is we will answer it but for now we are left guessing.
Do you want to propose an ASW DDH or a power projection DDH, if you want the latter then the Absalon/F125 is your answer.
Pick a navy and define a role and this will become much easier but at the moment is is remarkably unclear what it is that you are asking for.
I apologize for my ignorance and yield to your magnificence
Quite possibly one of the most sensible things that you have ever done.:rolleyes:
Just to add another point in regards to the comparison by the Author. I do believe it had a great deal of value………as only such comparison could provide. As a matter of fact I have know doubt I will refer back to it from time to time for general information. Especially, in general layout and size comparisons.
But such comparisons are useless without context, the point stands.
Example: Cavour is a better ‘pure carrier’ than a Mistral, well so what?
Of course it is, Cavour is the primary aviation asset of the Italian Navy, that Navy also has the San Giorgio class amphib ships. The French Navy on the other hand planned to have two fleet carriers so has no need to fly fixed wing aircraft from the Mistral class. They do however require long range amphibious support ships so they gave them well decks. The reality is that despite both being large ships with flat decks they are actually meant to do different things, so why bother comparing them?
Thus a one for one comparison without any context is a complete waste of time as it tells you nothing that is not already available and gives results that have no purpose.
I do not dispute that this is an excellent example of information collation and a remarkable demonstration of artistic prowess.
Your point it well taken…………That said, you are not saying we shouldn’t make comparisons???
Make them if you like, but be aware of their gaping limitations.
I should add that I admire the skill of the author but I see no point to his comparison exercise.
