From the article:

The Navy is refurbishing half of the remaining 22 Ticonderogas, enough to protect a planned eleven aircraft carriers into the 2030s. But the other eleven ships will start to age out in 2020.

And why aren't we refurbishing ALL of them?

I wonder if Barack HUSSEIN 0bama has an answer to that question.

This is a multi-faceted problem, which I'd like to address from the viewpoint of an experienced naval ship designer. The CG-47 is flat OLD. They are based on the Spruance (DD-963 hull and machinery design, had the SPY-1 radar squeezed into them, and then ridden hard for 30+ years with insufficient time and $$$ spent to keep them in good shape. Also, their combat systems at this point are approaching obsolescence. And no one in either party has been willing to give up the cost of social programs to have built a replacement class. The US has no cogent overall national goals or policy that are so necessary to understanding the requirements for a replacement class. That is why we've built so many blinkin' Burke-class DDGs. But even that class has the limitations imposed by physics. You can stuff only so much into the toy box. I agree with another poster who implied we are seriously overdue for a replacement cruiser class. And BTW, we should also have a replacement destroyer class under construction, and a follow on to that on the drawing boards. But we don't have those either. Instead a certain Deputy SecNav chose to pump up the total number of ships in the Fleet by buying that seriously poor excuse for a combatant called LCS.

Time to get off my soap box. PM me if you want more info/details.

Not enough ship left to refurbish. The ships getting the refurbishment are the youngest, best condition ships.

“And why aren’t we refurbishing ALL of them?”

That’s exactly what SHOULD happen. It’s infuriating that the military, and the government in general, is so reluctant to do the most cost effective thing in a lot of cases.

Another sterling example is ending F-22 production after only 187 aircraft, instead of 600+. Now, of course, the government is champing at the bit to start a next gen air supremacy fighter program at the cost of untold billions...
