SECTION I - FOREWORD
I-1. NORTH CAROLINA was damaged by a submarine torpedo which struck the port side abreast No. I Turret. The holding bulkhead failed and permitted limited flooding inboard. The torpedo protection system in way of the hit is thinner than amidships as necessitated by the speed characteristics. Abreast Turret I there is one less torpedo protection bulkhead and, therefore, one less torpedo protection layer on either side of the ship. The Bureau has given consideration to the addition of blisters and to certain recommendations for increased underwater protection. Blisters have not been added principally due to their adverse effect on speed.
I-2. The ship was not at General Quarters when hit. Speed was immediately increased from 19 to 25 kts. The 5 1/2° list was removed within six minutes. Turret I remained operable. The flooding, although extending inboard of the holding bulkhead and above the third deck, was not extensive. Progressive flooding was minor. Loss of life was small. No fires occurred as a result of the flash. There was no machinery damage, and shock effects were not severe.
I-3. It is considered that the ship's force handled the casualty in a very efficient and businesslike manner and that the ship generally absorbed the damage without serious effect or marked loss in fighting efficiency. It is believed that continued effort should be directed in new large ship design to prevent failure of the holding bulkhead.
I-4. This report is based upon the war damage reports from the ship and the repair activities. The PLATES were prepared by the Bureau from sketches, plans and photographs.
: To destroy a ship - its fighting capabilities
: - it is not necessary to destroy the
: armoured part. If the superstructure is
: destroyed, the ship has no sensors, no
: radars, no directors... If the bow is
: destroyed, the speed is reduced massively
: etc. Also the deck armour is much weaker...
: And for sure it would be possible to design
: missiles to destroy also the strongest
: armour (e.g. the armoured belt and parts of
: the turrets) without problems, if armour
: would be still in use.
