USN:
Within one week of her collision on May 6, 1956, with Fletcher class destroyer USS Eaton (DD-510), Iowa class battleship USS Wisconsin (BB-64) was able to enter the drydock at the Norfolk Naval Shipyard. Repairing her smashed bow would have taken considerable time and with the battleship already having been selected for training exercises that summer, time was in short supply. However, an interesting solution was put forward.
Nearby was the Newport News Shipbuilding Yard. Sitting idle in the Yard was the uncompleted sister to Wisconsin, the battleship Kentucky (BB-66). Kentucky had languished at Newport News since work had been suspended on her in 1950. However, her hull had been completed and this meant her bow was pristine and ripe for the taking.
It was decided to simply cut the bow off of Kentucky and graft it onto the hull of Wisconsin. Workers removed about 68' of the forward bow of Kentucky and loaded it onto a barge where it would be transported across Hampton Roads to the Norfolk Shipyard.
Workers at Norfolk cut away the damaged sections of Wisconsin's hull, making way for the new 120 ton section of Kentucky's bow. The operation was carried out at a lightning pace. Within sixteen days, the bow of Kentucky was successfully grafted onto Wisconsin.
Wisconsin was ready for trials by the end of June, just under two months after her collision and a little over a month after she first entered the drydock. The operation a success, Wisconsin was able to carry out her scheduled Midshipmen training cruise, departing Norfolk on July 9, 1956.
