How long does it take to build a ship and/or repair a critically damaged one

Also how long will it take for US to repair a critically damaged carrier and how long will she take to build a new one to replace those that had been sunk or too badly damage to worth repairing.

Thanks.

Why just the US? How long will it take China? How long will it take Japan? How long will it take Korea?

It depends on their damage control capability (and in this regard I do not believe there is anyone as good as the US...they simply have the best training and experience). it also depends on what facilities are available and how far away they are...also, in war time, it depends on what conditions those facilities are operating under. If they themselves are being threatened or attacked, then it makes a difference.

In World War II there were several times, with US Aircraft Carriers and other vessels that what was thought to require several weeks repair were litterally turned around in a single marathon overnight effort so the vessel could go back into harms way.

With today's electronics, depending on how well they were built for maintainability (ie. can you take a damaged unit out and simply plug in a new one, or is there all sorts of dissassembly and rewiring required) those parts could be turned around very quickly depending on blast damage or the lack thereof.

Within 72 hours more ships would be dispatched to replace a damaged Aegis ship.. The same for a CVN. The USN has numerous ships in "surge" status. Ready to depoly on very short notice.

I doubt if in a conventional war a CVN would be sunk. Severe damage is very possible.

In January 1969 fire and explosions ripped the aft end of the USS Enterprise CVAN-65 to shreds off the waters of Hawaii during a training excersise. It took only 6 weeks for the shipyard at Pearl Harbor to repair the damage.

In July 1967 fires and explosions did greater damage to the USS Forrestal CVA-59 off the coast of South Veitnam. The damage was so severe the ship was widthdran to the Norfolk Naval Shipyard in Porthmouth VA for repairs that took over one year.

Thanks Jeff and Popeye,

Now let us look at more nation as Jeff had pointed out before. What about Japan, Korea and China? And what about major European countries such as UK, France and Germany? How long will they take to repair their ships or replace one that is critically damaged.

As mentioned before by Popeye, replacing the ship damaged in frontline is easy, but that is for US context only (I believe) and I assume that there are alot of sailors to do the job well too. However in other nations such as Japan, China, Korea, UK, France, Germany, is replacing of hardware that easily and are we looking at sailors and other personnel availability too.

Thanks.

Korea and Japan have many systems and the same as, or similar to US...and they would definitely get assistance from US personnel and bases in any allied actions.

Yes. But that is replacement of hardware. What about their sailors and support personnel? It take a long time to train 1 man and I doubt it would be feasible to train alot of men and keep them as spare.

My point is simply that the Koreans and Japanese would likely find an ability to get repaired much quicker in those instances where US facilities can help them (they are much more numerous) than if they had to return to their own specific bases and facilities in all cases.

Navies often have more sailors than they do ships to crew; it is because of not all the sailors is immediately available for duty. Some may be on leave, temporarily ill, etc.

That topic raises a question for me.
The CVN-77 was laid down in sept'03, launched in okt'06, and will be commisioned in '09. That's roughly six years.
What's the minimum time e.g. for the US to built a CVN and bring it into service under wartime conditions?

Actually CVN-77 will be comissioned late this year(Nov or Dec.) It take 7 years from the first steel being cut to build a USN CVN. Then up to three years to outfit and train the crew with airwing. That's 10 years.

The US hasn't had a wartime economy since 1945. The fastest they bought a carrier from keel laying to comissioning was USS Hancock. Keel laid Dec. 1943 - Comissioned April 1944.

Agreed. If there were a real Naval war where such US Navy vessels were threatened, severely damage, or even sunk, you would see times compress significantly, even for the nucs.

In addition, I am willing to bet that you would see the Sea Control carriers come out in more numbers and faster with derivitaves of the Osprey to handle AEW and ASW off of such vessels, in addition to decent airwings of F-35s.

How fast could they be commissioned? I am not sure...but I bet they would be a lot faster than they are now in relative peace time (t least for the Navy in terms of at sea threats).
