Since USS America LHA-6 doesn't have a welt deck but an extended hangar deck shouldn't she be seen as a VSTOL carrier rather than a LHA ?
No.

LHA stands for "Landing Helicopter Assault," and the America will be used in most cases to conduct US Marine Air Assaults using helicopters on foreign shores. It however also has a capability to become fixed wing aircraft centric and operate as a carrier.

But make no mistake, it was designed to allow Ospreys and other rotor aircraft to carry troops into battle whenever necessary. In doing that, it also will carry a squadron of strike fighters to assist the troops conducting the assaults.

Also when necessary, they can be used to provide much stronger air support for an entire Amphibious Ready group (ARG) or as an escort carrier for large convoys or other task forces.

A "air centric" flat top equipped with F35B will basically mean a ARG will not have to rely on a fully blown aircraft carrier for SEAD, recon and surveillance missions

Current ARG use harriers which are good but can't do the full spectrum of missions a ARG with F35B will be able to do it

So adding a few air centric America Class will basically make a good thing better the F35B will have a platform to land, refuel and reload for a short air campaign

Actually I would say that the two Queen Elizabeth carriers will basically be doing what a USN ARG does
 
I really don't understand what you are trying to state. I really don't:confused:

I think, that information is classified.

The carrier deck ist 60 ft/20 m above the waterline and there are photos in the internet that show green water over the deck while limited operation is in progress (take off from the waist for example).

Yes :) thanks for your help European guy ! :)- sea state i have read also sea force, same.

CDG can use aircrafts up to 5/6 and i would like know for more big US CVN.

CGD use a special system for compensate its lower displacement

But what distinguishes our CVN from the other is the system Satrap Indeed through this system aircrafts will be up for sea force 6 (6 m cavity).
How does it work there?
The CVN is equipped with 2 System Stabilization flying deck
It is the systems Satrap and Cogite
The Satrap (Systeme Automatique de Tranquilisation et pilotage ) authorizes the fligth of the 20-ton aircraft by sea force 5 and 6. Prior to the french CV could authorize rhe flight of only aircraft of 12 tons by sea force 3 to 4.
The Satrap (based system of a small train and little wagon lies under the flight deck) pilot the boat, stabilizes the roll within a range of + / - 3 °, compensates the movements of the ship.
It consists of a central computer which gives instructions to “actionneurs”. The actionneurs include a series of 4 robot for the steering gear, three machines for Cogite and an robot for each of 4 wings stabilization.

Very interesting but error for
The adoption of nuclear propulsion made it possible to increase the capacity of cargo jet fuel 5000 m3et ammunition to 600 tons

CDG carry 600 t ammunition and 4000 m3 fuel, JP5, Clemenceau class 2000 m3.
In more CDG as CVN carry 1000 t Fuel usable by his escort

For comparison
Nimitz : 3000 t and 9000 m3 !!!
Enterprise : 8500 m3
Kitty Hawk : 1200 t, 5900 m3
America : 3100 m3
Wasp : 1200 m3

F-35s deploying to US carrier in November might not be fully operational
By: DAN PARSONSWASHINGTON DC Source: Flightglobal.com in 5 hours
Plans to test a Lockheed Martin F-35C aboard a US aircraft carrier in November are on track, but both aircraft scheduled to deploy to the Pacific may not be capable of taking off and landing from the ship.

The C-model F-35 will be the US Navy’s carrier-based version of the jet and will be the last to enter service in 2018, following the Marine Corps and air force variants. Lt Gen Christopher Bogdan, speaking at a meeting of the programme’s joint executive steering board in Oslo, Norway, said the deployment to the USS Nimitz in the Pacific Ocean was on track despite lagging software development and flight restrictions resulting from a June engine fire that damaged an F-35A prior to a training flight.

However, work is ongoing to determine if both aircraft slated to deploy will be fully capable of performing carrier launches and landings, Bogdan says.

“We have some work to do as we lead up to that point in November,” he says. “That work we’re doing now will decide whether both airplanes that go to the ship will be capable of doing arrestments and catapult launches or only one of them will be and the other airplane we will leave on the deck to do logistics testing.”

“The November deployment will happen. It will most likely happen with two airplanes. Whether both airplanes will be fully capable of doing all the work remains to be seen,” he says.

The JESB convenes every six months and includes representatives from the F-35 joint program office (JPO), all three US military services that are buying the jet and acquisition officials from the programme’s eight partner nations. The September meeting was overshadowed by a recent US Government Accountability Office (GAO) report criticising the JPO’s estimations of the lifecycle costs for the aircraft.

“The annual F-35 operating and support (O&S) costs are estimated to be considerably higher than the combined annual costs of several legacy aircraft,” the GAO report says. While the F-15C/D, F-16C/D, AV-8B and F-18A-D will cost a combined $11.1 billion over their service lives, the F-35 will cost $19.9 billion, the report says. While the Defense Department has begun cost-saving efforts to bring total per-jet lifecycle cost down, the JPO did not base its current assumptions on the service’s actual budgets and therefore “may not be representative of what the services can afford”.

“In addition, DOD has not fully addressed several issues that have an effect on affordability and operational readiness, including aircraft reliability and technical-data rights, which could affect the development of the sustainment strategy,” the report says.

Bogdan says the GAO was given eight months of open access to the JPO’s records to form its analysis, but dismissed the criticisms as based on assumptions that could “greatly change” within the 50-year service life of the aircraft.

“From my point of view, as the director of the F-35 programme, I am less concerned about cost estimates that occur 50 years from now, because those are based on a whole lot of assumptions and if you change even a little bit of those assumptions, those cost estimates change greatly,” he says.

“What’s more important to me is what we are doing today, when we have 150 airplanes, to reduce the overall lifecycle cost of the airplane for when we have 3,000 of them.”

Plans to bring the per-aircraft cost down to $80 million by 2019 are heavily reliant now on a production ramp to fulfill international orders.

Despite recent setbacks, Bogdan says current partners and potential foreign military sales customers remain committed. Discussions with Israel to increase that nation’s buy are progressing and could be finalised within months, Bogdan says. Norway’s first two aircraft are in assembly with delivery scheduled for late 2015.

“We have other nations out there who have been interested and are discussing potential buys of the F-35 despite the fact that we have an engine setback or in the past we’ve had some software problems,” Bogdan says. “Most of them look past those immediate problems because those immediate problems are not unlike anything you’ll find in most any airplane development programme."

USS America: LHA-6 amphibious sign the new ambitions of the United States

On 15 September 2014, following a maiden voyage, the Landing Helicopter Assault USS America joined the Naval Base San Diego. Head of the Class in a new series of buildings, it is the result of a substantial evolution of American doctrine for amphibious operations.

To replace the LHA Tarawa Class, the last building was called to active duty in the early 1980s, the new class of LHA America is derived from the last LHD (Landing Helicopter Dock) of the Wasp class, the USS Makin Island, admitted him to active duty in 2009 like similar buildings, buildings of class America can provide the C4ISR functions and serve the needs of the hospital ship with an initial capacity of 60 beds, which can be increased to several hundred by developing interior spaces.

USS Makin Island as the bridge of the America class was structurally designed to maximize the aerial maneuvers and timing of landing cycles, bunkering, takeoffs. The bridge has also been enhanced surface to withstand the heat generated by the nozzles of the MV-22 and the F-35B. Notable difference from the USS Makin Island, the first two buildings planned class America (USS America and USS Tripoli, under construction) do not have to write off. This means concretely that they do not embark on Schedule Skippers could land troops and equipment on the coast by sea. No future LCAC or SSC (Ship-to-Shore Connector) on board, the United States Navy waives it to conquer by force a beachhead on the coast.

Two reasons for this. The first is a practical one: giving up the strike, the building can carry more fuel and ammunition, while leaving sufficient space to accommodate its flanks in the MV-22 Osprey and the F-35B, much bulkier that the material they are supposed to be replaced (CH-46 and AV-8B). In battle, the standard configuration and provides hospitality and support of 12 MV-22B Osprey convertible for transport, six STOVL F-35B, four heavy transport helicopter CH-53K seven attack helicopters AH-1Z / UH-1Y helicopters and two MH-60S navalisés for rescue operations at sea. This is almost a third additional aircraft over the Wasp class.

The second reason is tactical, renouncing coastal landings (on the first two examples of this class of buildings only), the Navy and Marines equip themselves with a tool designed to operate in depth. Able to operate far offshore, well beyond the horizon, the America class provides great tactical flexibility by eliminating the constraint of finding a side capable beaching. Use of heliborne troops backed by helicopter gunships and F-35B allows to conduct an operation of conquest or destruction of key points well back from the coast. In the context of high intensity operations, the Navy and Marines have the means to focus efforts, with the ability to deliver a large volume of fire, then troops, at a given point, very quickly. The United States reconnect with the principle that in the helicopter raid in depth.
