The assessment explicitly rejects the possibility of an unsinkable warship. Claims of that kind predate Titanic, so the warning applies more widely than this proposal. The Defiant's projected usefulness comes from operating within a task group or task force. Its own helicopters, possible loyal sloops, and supporting sensors form part of that expectation, while the risk of sinking remains.
