How wartime losses changed survivability requirements

British experience in the First World War helped shape the survivability and damage-control practices used in the Second. American strengths in these areas are linked to the losses and lessons of the Second World War. Such lessons can fade, leaving a navy vulnerable when it forgets why protective measures were adopted. Clarke recalls his father and other naval architects noticing a change after the 1982 Falklands War: protective features previously considered possible budget savings became essential requirements. Naval personnel, civil servants, and politicians changed how they discussed and justified those features. Better power plants for the Type 45s would have been preferable.
