Record of Proceedings of THRESHER Inquiry

In September 2020 the U.S. Navy released the first tranche of documents from a formerly classified report into the sinking of the Navy submarine THRESHER in 1963. This is volume one of twelve. This 300 page large-format document, originally 8.5 x 14, is printed in full color to preserve the distinguishability of classification markings and other edits that appear in red in the original.
