Of course if you build more of them, then you amortize the R&D costs over more ships and the per-ship cost goes back down.
********************
And, if the ships were being built with NON-union workers the cost per ship would be significantly less!
The Pentagon awarded a fixed-price contract to General Dynamics to build these three destroyers, replacing a cost-plus-fee contract that had been awarded to Northrop Grumman. The first DDG-1000 destroyer is slated to cost $3.5 billion (and it is well over 60% complete) see my DDG 1000 Site and watch the video there of the second large section being rolled out and mated up to the first at the bottom of the picturesb.
The second vessel is to cost $2.5 billion, and the third near $2 billion.
Originally both the 1st and second vessel were estimated to come in at 3.5 billion each which would have made the 7 billion.
In my US MILITARY BUILDUP PROPOSAL. I propose that with a strong economic turnaround, we should go ahead and build eight of these.
