Of the many, many flaws and failures of the LCS, the survivability issue is indeed a bit overblown.
Pretty much any modern combatant will be sunk by a heavyweight torpedo, and rendered combat-ineffective by any sort of missile hit.
I always have to laugh at the oft-mentioned “Somali Pirate Chasing” mission. You’ll never see the LCS doing that because it has such poor endurance.
A few Predator UAVs with machine gun pods would work better.
That's the problem. The mission should be pirate killing, to hell with chasing them or arresting them.
