 A report from the U.S. Navy's Pacific Submarine Fleet determined that Japanese anti-submarine warfare (ASW) forces failed to uncover the maximum test depth ability of U.S. fleet submarines during the war.However, the report made no finding as to whether or not Japanese ASW forces altered their depth charge attacks to deeper settings as a consequence of May's revelation to the press.Sometime shortly before or during the U.S. entry into World War II, May became involved with Murray Garsson and Henry Garsson, New York businessmen with no prior arms manufacturing experience who sought lucrative munitions contracts then being awarded by the U.S. Government.
