Veja o CdG, como tem um convoo muito maior do que o do SP, apesar de ter menor comprimentos, mesmo que por meros metros...

PA2 Aircraft Carrier
DCNS has been working on definition studies for ‘PA2’, a second aircraft carrier for the French Navy, since 2003. The aim is to ensure the continuous availability at all times, to France and to Europe, of a key power projection capability, air/sea dominance and deep strike missions. From the time the PA2 project received the initial go-ahead in January 2005, DCNS and its partners launched a study to exploit the similarities between the British CVF (Carrier Vessel of the Future) programme and the French PA2 programme. This led DCNS to define a French version of the CVF, dubbed CVF-FR-V2i, to meet the PA2 requirement.
The need for a constantly operational carrier-based air wing was confirmed in the 2008 white paper on defence and national security. The French government has put off its final decision concerning this programme until 2012.
To maintain its skillset, DCNS continues to study, in liaison with the DGA, variants of the proposed carrier meeting the needs of the French Navy and international customers. These studies are conducted as part of the Group’s Championship improvement strategy to meet customer needs to the best of our ability and in compliance with strict budgetary guidelines.
The version presented at Euronaval 2010 has a displacement of 60.000 tonnes and is optimised for efficient flight deck operations (90-metre catapults, sizing of deck and hangar areas, munitions payload), high operational availability, low cost of ownership and compliance with Bureau Veritas Naval Rules for habitability and safety.
Carrier group centrepiece
The PA2's capabilities include air/sea control over a wide area, strike attacks against land and maritime targets along with missions as the centrepiece of a French carrier group or in cooperation with allied forces. On operational deployments with an air wing of 40 aircraft, the PA2 will be able to carry out up to 75 air missions per day for extended periods.
Optimal availability
To increase the French Navy's force projection capabilities, every effort is being made to ensure that the PA2 offers high at-sea availability. In particular, DCNS proposes to apply lessons learned and the progress achieved in through-life support for French warships in recent years. Operational availability will be improved by ensuring that the ship is laid up less often and for shorter periods. Provision will also be made for easier access, handling and removal of heavy or cumbersome equipment.
Crew first
The PA2 is being designed for reduced crewing, specifically a complement of just 900. The ship will also accommodate an air wing of 620, a command team of up to 100 and up to 100 other passengers or crew for special missions. Every effort is being made to improve living and working conditions. Accommodation and living areas will be separated from work areas.
Platform and propulsion system
The design is for an ‘all-electric’ ship with a powerplant comprising three diesel-alternator sets in the engine room with a gas turbine and backup diesel-alternator set under the island.
Propulsion will be provided by three shaftlines with fixed-pitch propellers.
The direct-drive electric propulsion motors will have power ratings of 2x19 MW for the port and starboard shaftlines and 25 MW for the centre shaftline.
Flight deck
The proposed design calls for two 90-m catapults and additional decks under the hangar deck to ensure more space for aircraft operations. The flight deck will be operational up to sea state 5/6. The air wing spaces will be both larger and more efficient. More specifically:
- fixed-wing aircraft will be launched at 300 km/h by two 90-m catapults
- flight deck launch rate will be one aircraft every 30 seconds, or a complete strike of 24 in about 12 minutes
- air wing and flight deck facilities will be fully interoperable with the latest aircraft types operated by leading navies.
The PA2 will be able to deploy an air group of 35 to 40 aircraft including some in the 15/25 tonne class:
- Rafale combat aircraft, in the F3 configuration, taken as the main sizing template, along with provision for three E-2C airborne early warning aircraft
- oblique runway inclined at 8°30’ to ship’s centreline
- midships island between the two lifts
- hangar with storage space for part of the air wing, but reserved primarily for aircraft maintenance
- additional storage areas for support equipment and optional items
- two starboard lifts, each with a useful payload of 36 tonnes, linking the hangar to the flight deck.
Combat system and weapons
The PA2 systems are designed to deploy and command an air wing and provide self-defence capabilities consistent with the defensive capabilities of the carrier’s air wing and the carrier group as a whole.
The systems include the carrier’s combat system – with its surveillance sensors, EW suite, self-defence systems and CMS – an integrated bridge with its navigation system, a multi-service network and the communications system. The Setis® CMS is based on that developed for the FREMM multimission frigate programme.

- Accommodation: 1,690
- Flight deck, area: 13,400 m2
As catapultas do PAs francês são americanas (C13-3 a vapor derivadas das catapultas da classe Nimitz)Andre Correa escreveu:Pois, dificilmente escaparemos do Hawkeye, ou o seu modelo sucessor, pois no ocidente ninguém mais tem escala para fazer um AEW&C Navalizado além dos EUA.
A questão da catapulta, eu vejo apenas como atrelada ao vencedor do FX-2, e também virá do mesmo "fornecedor".
Resta saber qual será o tipo, se será a nova magnetica, ou ainda a vapor, pois acredito que a magnetica deverá ser mais capaz do que a à vapor, portanto, pode não ser necessário os 90m para um eventual SH.
Ainda temos 4/5 anos para fechar o negócio, e começar a construir em 2016/2017, realizar testes a partir de 2023, e entregar em 2025...
