On 10th November 1966, the Nautilus SSN-571 collided with the USS Essex (CV-9) while running submerged about 350 miles east of Morehead City, North Carolina, during underway replenishment exercises. Both ships returned to port unassisted. The submarine received extensive damage to its sail area and went to New London. The carrier sustained an open hull cut in the bow area and proceeded to Norfolk, Virginia.
