Much of the recent discussion of the current Littoral Combatant Ship (LCS) program and the proposed new frigate FF(G)X involves the “survivability” of both classes. Numerous senior civilian and uniformed officials have called for the FF(G)X to be “more survivable” than the current LCS. Casual observers may not know how much information goes into determining this feature of a warship design. Before the Second World War and for some time after, “survivability” was primarily concerned with how many “hits” of a certain size projectile a warship could sustain and still be mission capable. In the postwar era, the concept of survivability changed based on a new ethos in surface combatant design, the advent of nuclear weapons, and advances in detection, communication, weapons, and countermeasure technologies. In fact, a warship’s active and passive defenses against attack from aircraft, cruise missiles and underwater weapons have effectively replaced armor and other elements of physical resistance to damage, making a warship’s “survivability” more akin to a combat aircraft than past combatants.
