Actually there's a recent spate of articles indicating that the Navy won't proceed with the ammo, which jumped to $800,000/round.
While I agree with R&D being necessary, even cutting back to only three ships this seems like a tremendous sink hole of money.
So, Extremely expensive R&D, Avg. Cost/Ship $7.5B which is more than nuclear powered Nimitz Ronald Regan ($6.5B) it leaks, uses ammo that is 10x more than projected in terms of cost. This needs to be scrapped. I think that's what's missing really in Defense Spending, the ability to honestly start looking at red flags early on in a project so we don't develop these sink holes of one off (or three off) technology.
I have to also think that maintenance costs will be extremely high as well. I'd love to know what the lifetime costs of the three proposed ships would be.
