USS Franklin CV-13 ...also known as the ship that would not die. 1-1This is a long report. An effort has been made to present a comprehensive summation of the many design and damage control problems which were disclosed or emphasized by the war experiences of Franklin. In addition, various pertinent war experiences of other large carriers have been considered in this report. 1-2The damage sustained by Franklin as a result of the actions of 13 and 15 October 1944 was superficial and is included in this report only for the purpose of rendering her damage history complete. The major damage sustained in each of the actions of 30 October 1944 and 19 March 1945 demonstrates the effectiveness of bomb hits when received by aircraft carriers during the extremely vulnerable period just prior to and during periods of launching strikes. The damage sustained on 30 October is a reasonably good example of what may be expected from a suicide plane crash and subsequent fire on a carrier having a full complement of planes on board which are gassed but not armed except for small caliber ammunition. Similarly, the damage sustained on 19 March may be considered as about the maximum to be expected from fires and detonations of large numbers of bombs and rockets on the flight and hangar decks when a carrier having heavily armed, fully fueled planes aboard is hit by one or more bombs properly placed. 1-3The latter two cases of damage to Franklin illustrate thoroughly the ability of modern U.S. aircraft carriers to survive extensive damage from plane crashes, fire and heavy bombs. The basic design and construction of this class of carrier, which was developed prior to World War II and therefore without the benefit of war experience, is favorably reflected in the manner in which Franklin absorbed heavy damage. Materiel alterations and improvements in damage control organization and technique during the war further increased the ability of this class carrier to minimize potentially severe damage. At the same time many lessons have been obtained from the experiences of Franklin and other cases of war damage and results of this knowledge have been and will be incorporated in existing ships where feasible and in future design and construction. 1-4This report is based on the references, inspections of Franklin upon her return to this country, and informal interviews with various officers attached to Franklin by representatives of this Bureau.
