Two types of patches were made by the Pearl Harbor Navy Yard to help in refloating USS Nevada. A large patch, intended to cover the large torpedo hole in the battleship's port side, proved unsatisfactory, since the ship's hull was too badly distorted to permit the patch to seal the hole. After much work, this patch had to be removed before Nevada was placed in drydock. More successful were smaller "window frame" patches that were used to close up underwater bomb damage.

This page features views of patches prepared for use in refloating USS Nevada.
