The EMALs system is working. Some, but not all, of the weapons elevator problems have been corrected. So I’d say the FORD is closer to full operational capability on the face today’s facts.
As of a few weeks ago it was declared inoperable training ship FWIW
It is back for more millions in repairs which the Navy budget does not have. It will be many years, at best, before the problems can be fixed - if ever. This is not the ordinary teething problems many systems have. It is a number of major design flaws from the initial decision to build untested systems and fix them on the fly.
All the elevators have to work to make the ship functional and is now slower than Nimitz class - and that fix is not happening any time soon. The EMALS system ‘works’, but cannot do sustained operations. Personnel were very dispirited after retuning from the trial about this huge flaw.
There is no fix for the Spy radar (now abandoned), nor for the sewage system which has to be purged multiple times a day - bad plumbing design - only fix: rip and replace - doing that involves major structural alterations and possibly effects sea worthiness, not to mention many billions of dollars. And those are only a few of the problems.
Full functionality depends on if there actually is a fix, or do systems have to be ripped out, and also on the Navy budget - are there billions more to sink into it?
Would it be better to leave it and move on to the other four Ford Class ships and get it right? Which plan is more efficient, which costs less? With all the mil budget cuts coming, it would seem that there will be no more major build funds for the Ford. Hence, inoperable training ship which, incidentally, the Navy desperately needs.
On the bright side, the Zumwalt finally fired its 30mm guns. The ship will likely end up as a stand off missile platform, as it is not survivable in a combat situation.
