Ironbottom Sound
On US aircraft carriers this area is called the combat direction center (CDC). The United States developed their Command Information Center concept circa the winter of 1942–1943 and implemented it in a surge of refitting and retraining during 1943 after post-battle action analyses of battles in 1942 from the battle of the Coral Sea through the losses at Ironbottom Sound during the protracted Solomon Islands campaign.
