For it's size it carried a formidable punch and wasn't a bad fighter either, didn't the USN use them for a short time as fighters operating off the CVS carriers?

True..each CVS deployed had a small,4-6 aircraft, detatchement of A-4's for fighter cover.

one of the great selling points of the CVF is great sortie rate 110 sorties compared with a Nimitz sortie rate of 140 and the fords 160-220 at a 1/4 crew

You must remember that a USN CVN is the center piece of a CSG(Carrier Strike Group). The USN CV suppourts the rest of the CSG with, major medical dental support. The USN CVN suppourts the rest of the CSG helos with major maintance. Repair work(shops), fabraction shops, admrial staff, mail, some logistical suppourt. Refueling at times. Personell transfer etc..etc...

As I have said many times..you have to see it to truely believe it and undersatnd the inter workings of a USN CVN.

some less than cheery news from the Ford class
Price tag for Navy's new aircraft carrier on the rise, GAO says

The next-generation aircraft carrier Gerald R. Ford, under design at shipbuilder Northrop Grumman Newport News, faces "substantial risk" of cost overruns that could complicate the Navy's plan to increase its fleet, a federal report scheduled for release Monday says.

The Government Accountability Office, a watchdog for Congress, said that this "likely" cost growth "may force the Navy to sacrifice" other vessels in its 30-year plan to grow the fleet to 313 ships from the current 279, according to Bloomberg News. The business news service first reported the GAO's findings and quoted from the 41-page report.

The GAO said that delays in testing new key technologies - including a dual-band radar and systems for launching and landing fighter jets - could lengthen the carrier's construction time and drive up costs, Bloomberg reported.

Those conclusions echo testimony the GAO gave in late July during a congressional panel's hearing on the Navy's shipbuilding program.

A spokeswoman for U.S. Rep. Roscoe Bartlett, R-Md., the member of the House Armed Services Committee who requested the report, confirmed the GAO's findings.

The report "indicates it's highly unlikely" that the Ford, the first of a new class of nuclear-powered carriers, will meet the Navy's budget or construction schedule, said Lisa Wright, Bartlett's press secretary.

In a statement Friday, Bartlett said the GAO revealed that "the development of three critical technologies has been delayed to such an extent" that the Ford "must experience 100 percent success" during construction to meet the Navy's current $10.5 billion procurement budget.

The Navy has struggled to contain shipbuilding costs, and first-of-class ships in four of the service's current programs have experienced cost creep, including the littoral combat ship, the LPD-17 amphibious warship, the DDG 1000 destroyer and the Virginia-class attack submarine. Northrop Grumman Newport News shares construction of those subs with General Dynamics' Electric Boat.

The price tag of the George H.W. Bush - the 10th and last of the Nimitz-class aircraft carriers - has grown by $847 million, or 17 percent, over its initial budget. It is now under construction at the Newport News shipyard and scheduled for delivery next year.

At the July hearing, the Congressional Budget Office said the Ford carrier, known as CVN-78, could cost at least $1 billion more than the Navy has budgeted.

"In this budget environment, that's going to be a difficult sell," Bartlett said Friday.

He raised the possibility of revisiting the idea of building a larger number of smaller carriers, which "might provide more value" to the Navy than a few "super carriers."

The Navy said Friday that it would not comment on the GAO's report until it is officially released. However, Capt. Michael Schwartz, program manager of the Ford carrier program, said the service believes its can acquire the Ford under its current budget.

"The risks in the program relating to development of new technologies are clearly defined and being managed," Schwartz said in a statement. The purchase of materials and the design and advance construction work at the Newport News shipyard "are meeting expectations for cost performance," he said.

While the new technologies going on the Ford have posed "challenges," shipyard spokeswoman Jennifer Dellapenta said in a statement that "we are confident that in the end, we will be successful in incorporating them on CVN-78."

With the Ford's computer-assisted design now about 74 percent complete, the Navy expects to award a contract to begin full-scale construction in spring 2008. Completion is scheduled for 2015.

The Ford is the first of three new carriers in a $35 billion program to replace the carrier Enterprise, the Navy's first nuclear-powered carrier, and the Nimitz-class fleet. The new Ford class is designed with a host of high-tech improvements, including an ability to launch more aircraft combat sorties and to operate with several hundred fewer crew members.

Two of the improvements that have faced delays cited by the GAO are an electromagnetic aircraft launch system, which replaces steam-driven catapults, and a new aircraft arresting system. They are being built by San Diego-based General Atomics. Raytheon Co. is making the new dual-band radar that also has faced delays.

Bloomberg News reported that officials with those two companies expressed confidence that technical flaws and delays outlined by the GAO are being solved and won't affect the Ford's delivery schedule.

The above article is very typical of what happens in the warship building "industry" in the USA. It boils down to this...

There are really only three or four companises that build warships in the US. And only one that can build a nuclear carrier. That would be Northrup - Grumman in Newport News VA. That company is well know for cost over runs, delays etc..They get away with it also..because they have a monopoly on the CVN building business..sad but true.

I wonder whether there are too many major new technologies being attemped at the same time as a new ship design. Maybe it would have been better to introduce them, or at least trial them, on the existing Nimitz design.

The infrastructure is just too expensive to maintain. If you have a CVN capable compnay and you lose out on a contract your out of business because you can't keep your company afloat while you wait for another order to come down the line, because it takes years.

Modernized Island

CVN 77's island design includes a modified main mast, an integrated aft mast, transparent armor windows and many navigation and communication systems upgrades. The USS Ronald Reagan (CVN 76) was the first carrier to incorporate many of these changes.

1)Aft Mast

The AFT mast was relocated from the flight deck to the island to put it in closer proximity to other radar systems.

2) Main Mast

The main mast pole is a tapered square pole in lieu of a round mast pole. This design keeps electrical and piping systems enclosed for survivability purposes. The larger size also allowed for the following changes:

-Waist high safety rails
-Easy access to all areas by internal ladders

3) Primary Flight Control

Increased square footage and larger window in Primary Flight Control has improved visibility of the flight deck for the Air Boss and squadron representatives.

4) Bridge

Larger windows are included in the Navigation and Flag Officer Bridge areas for better visibility.

5) Outboard Weapons Elevator

An aircraft weapons elevator was relocated from the centerline of the flight deck and now extends up into the aft section of the island, allowing for more efficient movement of aircraft ordnance during flight operations.

Thanks for the clarification about that Popeye. I was worried from some of the things I had read that a whole lot of new systems were all being tried out in the new design and I could imagine a lot of teething problems.

No problem..I know when that ship(CVN-77) is comissioned it will take a while to work the "bugs" out...:(..That's just part of the game...

some more news on the CVF long leads are being ordered the genrators and now the IFF
Please, Log in or Register to view URLs content!

Defence Minister Lord Drayson has awarded the first contract for the new equipment that will be fitted to the 65,000 tonne aircraft carriers MOD has announced it is to order.

The equipment, advanced Identification Friend or Foe electronics that will help protect the ships and their aircraft, is to be designed and manufactured by SELEX Communications. This contract, initially worth over £1M, was awarded following competition.

Lord Drayson, Minister of State for Defence Equipment and Support, said:

“Today’s announcement is another milestone for the Future Aircraft Carrier programme. We plan to award further contracts for the production of equipment for these ships over the coming months as the shipyards begin their preparations for the start of construction work. Beyond this first equipment order, UK and France are cooperating closely in a number of key areas, and are exploring future joint procurement opportunities, notably for Power and Propulsion and some key aspects of the Mission System.

“This is a very exciting time for everybody in the MOD and in industry who are working on this project. We intend that the production of these ships will transform both the Royal Navy’s capabilities and Britain’s maritime industrial base over the coming years.”

The IFF equipment ordered today will ensure that commanders on the new carriers will be able to distinguish between friendly and hostile aircraft in complex and stressing combat scenarios. The equipment will be delivered in time to be fitted to the ships before they go into service later in the next decade.
