I wont disagree but not because of internal bulkhead structure. While there have been many high visibility technical snafus, from what I understand (and this is just hearsay) one of the biggest issue that never gets discussed is that the ships were planned to operate with a skeleton crew and it turns out to be not enough to maintain them. Of course putting more sailors on them raises their lifecycle cost through the roof so nobody wants to do that (might be a program killer). So you end up in a death spiral where the ships aren't maintained, they get worse, they fail more, can't be repaired, fail more, get CASREPs, etc.
Or so I've heard. Could well be wrong.
Not far from what I’ve heard and read. The Navy and the contractors believed that heavy automation would allow the radical crew size reduction. However, the automation didn’t work and the modular mission system takes up so much space that either they have to load a personnel module (which reduces flexibility and capability) to house additional crew to ‘normally’ run the vessel. However, the modular system has caused other compromises in the ships’ designs so while they’re ahead of ‘commercial’ ships they’re not close to where other Navy vessels are.
Another big problem is that the LCS is now to take on the missions formerly assigned to larger frigates and destroyers... without the organic equipment or crew.
