Both of the US Navy’s new combat ships, the DDG-1000 Zumwalt and the Littoral Combat Ship are designed to minimize crew size to save cost.

However, the LCS is a conventional hull form, and it has lots of open space in, both for modules, and for a lot of reserve bouyancy.

The Zumwalts, however, appear to be much more tightly packed, with less reserve bouyance relative to their size, and a tumblehome hull form for stealth that is suspected of having stability issues.

Galrahn at Information Dissemination suggests that perhaps the crewing and hull form created a ship with a serious glass jaw, much like the British battlecruisers at the turn of the last century:

More than any other form of damage control, flooding is best known for being managed by active means best represented in manpower. The reduction in crew creates an unstable situation in this regard, and while we are on this subject, let me note that I believe one of the real unspoken reasons Roughead wants to cancel the DDG-1000 is specific to the absence of flood control capabilities with that platform that has a relatively tiny crew. Ever read Friedman about ship design? If so, consider the hull form of DDG-1000 as you reflect upon the thoughts I’ve noted below.

If his analysis is correct, and I think it is, I find it interesting this is repeating almost in an almost exactly 100 year cycle.
