Sorry, but that's really not an accurate statement
Originally the DDX, then the DD21, and finally the DDG-1000 the program was going to be a class of 32 ships, with the large R&D spread out over that entire build. The R&D that has gone on with the Zumwalts is simply amazing stuff, and will be a game changer for the Zumwalts, as well as other vessels who will make use of that technology in the future.
But now, it has to be spread over three ships...not 32. So saying it is "procurement gone wild," as if though each ship will cost $7 billion is just not dealing with the realities of the situation as it developed.
Now, in 2013, the actual cost of the USS Zumwalt, DDG-1000, is going to come in at about $3.5 billion dollars. The second, the USS Monsoor, DDG-1002, is now expected tp cost $2.5 billion, and the third, USS Lyndon Johnson, DDG-1002, is now expected to come in at just over $2 billion. That's a total of $8 billion for all three ships, each of which is a 14,500 ton, high-tech cruiser sized fighting vessel with absolute cutting edge technology.
That's will be an average of $2.66 billion per vessel, which is high, but when you compare it to the $1.2 billion unitary cost for the 9,400 ton Arleigh Burke IIA, it is not terribly out of kilter, especially, as I say, since the build was cut back to just three vessels.
