Here's an interesting tidbit. From the most recent CRS report (1), we note that the LCS was designed to be able to deploy for at least 21 days, however, the ship only has food storage for 14 days. Assuming a few days sailing to and from the area of operation, the functional deployment of the LCS is limited to around 8-10 days. Of course, a mothership or replenishment ship could always tag along with the LCS and replenish it every few days but that seems highly inefficient.
One of the aspects of operating small vessels that seems not to have been understood by the Navy or by proponents of small vessels when they look at foreign navies and their small vessels is that most (all) foreign navies operate their small vessels in home waters where ports are just hours away. Trying to operate small vessels half way around the world, as the U.S. Navy does, presents significant logistical challenges. As I just said, the LCS is either limited to very short deployments or must have a replenishment ship tagging along at all times.
Of course, ComNavOps notes that the 14 day food storage capacity was for the original crew size. The Navy has since increased the core crew size by 20 berths (50% increase) which drops the food storage to around 10 days or less!
