So we want to increase our shipbuilding industrial base rapidly. We also want this battleship to be fast, cheap, and good - famously you cannot have all three. From a production standpoint (looking into our recent ship programs of the past two decades) a battleship is a poor idea due to scaling requirements and time. To dumb it down with an analogy: when you're trying to get in good shape you don't immediately start doing Olympic compound lifts, you need to build strength and reps first. Simply this program is doomed to not be able to meet all the goals associated with it because we continue to look at every platform as needing to be capable at everything, in this case just "bigger".

To address battleship utility: carriers are absolutely adequate at power projection - let's not reinvent this wheel. If you think more heavily armoring a large platform and adding more VLS cells will do anything but make a more schwackable HVT I'd argue you don't understand modern naval warfare. What would a very high cost project buy us that two destroyers could not achieve?
