Shared resource alternative
Don't forget expertise as well. Having built one of the largest shipbuilding facilities in the world Ingalls didn't have the expertise to build two medium sized cruise liners. I say Ingalls because a number of corporations have owned it through the years. The safest shipyard in the United States, Newport News, is now facing the possibility of having aircraft carrier orders delayed, something unheard of during the past fifty years. None of the other US shipyards have the capacity or expertise to build super sized aircraft carriers. Newport News faces the same possible layoffs and retraining a new staff in the future.
As a big proponent of a real power projection capability for the EU both within the French, UK and other navies, I have done a lot of searching sources to see if a plan to share a platform was ever entertained, particularly as part of the now defunct agreement on the anniversary of the "Entente Cordiale" to share the design to build Britain's two and France's second CV. Considering the considerable monies invested in joint fleets of AEW, now Strategic Lift and some lesser talked about 'comparing of notes' on the operation of SSNs and SSBNs, I would have expected (obviously in error) a plan to buy at least one UK CV and share air wing ops with the French Navy. If each deployment included either country's CV but consistently a joint air wing, op tempo and accumulating of operational expertise would really be improved. Not to mention that both countries could spend a lot more on the air assets and accompanying escorts and just take turns 'hosting' the air wing. Yes, we're talking about an enormous amount of sharing in terms of political and strategic priority setting. But the benefits would be almost immediate. France already has a working fighter for the decks and AEW aircraft. Buying more of the latter is not hard right now as the USN is recapitalizing with IIRC 89 new build E2s. Certainly, the catapults for one CV would not be as prohibitive in the absolute (though clearly more expensive per actual catapult system).
Furthermore, sharing decks between two different fighter systems (e.g. F35C, for argument's sake, and the Rafale M) would not be prohibitive. Even the USN, plans to operarte mixed F35/SH wings until they have enough of the former to replace the latter. And if no one keeps telling the French this is a hi/lo mix, no one would have to be offended
Also, while I appreciate all the talk about the Commando Carrier role, frankly both navies have spent years and serious currency developing and fielding capable ships for amphibious power projection. I still personally find the STOBAR configuration fairly compelling for the RN because of the bring back advantages.
For the most intractable bit, both countries would like occasionally to operate their ships in a purely national role. In that case, they would have to live with the tradeoff of saving ALL that money. I don't know if that means too much sucking up to your own ally to ask if you can do a joint op say to rescue your nationals off an unfriendly coast...
The furthest pie in the sky would have been to enlist other EU nations to contribute escorts and, why not, even some air assets to the CBG. Helos and some marines for a quick rescue would be the no brainers but when you see that Australia and Canada both operated standard USN issue F/A18s for decades in the land based role, you have to ask yourself why, for example, Be and NL couldn't have purchased a carrier capable fleet of fighters and designated one unit each to maintain carrier currency as their EU contributions to the CBG. Sp and It would also be naturals for this, having both operated types which could be so designated. Not just the Harriers for their CVL but also F/A18s for Spain and eventually F35s for both... Your thoughts?
