I'd think that would be a prime consideration in combat survivability. The old DLG and DDG that I served on had four boilers in two separate boiler rooms. There were turbines in two separate engine rooms. We could still be underway (though not very well) on just one boiler and one turbine.
The LCS/Frigates have no combat survivability. They have very little in the form of local defense. The only reason casualties will be relatively small is the small crew size.
Suitability of the crew is a naval non-issue; spending big bucks for two ships that are “state of the art” is. After all it’s Pentagon prestige that makes the military so grand - all those metals and ribbons you know. Besides the Navy - the ocean going component - had to have some dubious equivalent to the USAF’s unbelievably expensive and poor performing dud, the F-35. Just loading their Navy’s carriers with F-35s was not good enough, they had to have a signature center piece to display their grandness and innate PC stupidity. The poor US Army, has no really expensive weapons systems planned, so they came up with a ‘relatively inexpensive’ idea that makes the Navy and AF decisions pale - admit women to all combat positions.
And so the table is set for the US to lose any future or present war.
And their is still another year to go for O’s plans - wonder what his finale will be?
