The stats are crazy:

  Completed: 3
  Cancelled: 29
  Active: 2

Similar "stats" to the Seawolf class.

Planned: 29 Completed: 3 Canceled: 26 Active: 3

Yet, unlike the Zumwalts, they are considered a good boat.

The Seawolf was kinda the first attempt at a next generation attack sub while we were still figuring out the technology, making it far too expensive. But it led to the Virginia class, which has gone into mainstream production.

In some ways there's a similar situation with the F-22 vs F-35, though those two may have a bit more of a difference on roles and requirements.
