You have no idea just how right you are. The LCS-2 design has had “water wings” (large sponons) added to the stern to compensate for the lack of reseve bouyancy and the placement of the main mission module bay too close to the waterline. If that bay were to flood, not just combat damage but also issues with the doors, the ship would be a repeat of Vasa and Mary Rose.
Sorry, should have been LCS-1 design above.
