With respect, I disagree. I do disagree with the decision to only produce two Zumwalt-class ships, but I am glad that at least we will get two. It will be much better than zero.
...
I also disagree that I am intellectually lazy, because I have thought about the alternatives. There are two--better procurement or no procurement. I firmly believe that a better procurement procedure will not happen until there becomes a critical need for it, such as an open, protracted war with Russia or China. So that leaves the option of no procurement. We can simply keep Perry-, Burke-, and Ticonderoga-class ships until they cost their initial price tag every other fiscal year to maintain.
Having two means that they will not be deployed forward when they are needed. It also means logistical and support costs are incurred for just two ships that would normally be justified for a fleet of them, e.g. spare parts, engineering programs, training programs, etc. The money spent on those two could have paid for a lot of capable ships that could be protecting sealanes, protecting CVNs, performing strike missions, and the like. I'm willing to bet that one could build several upgrades Aegis destroyers for the same price.
Also, there will never be a open protracted war with Russia or China, especially not one that allows time to do a lot of new contracting. War with one of them would be over in a matter of days or weeks, not years. This isn't WWII--either someone's pain threshold will be reached quickly, or it will escalate to nuclear combat.
