From the Summary: "Names for Navy ships traditionally have been chosen and announced by the Secretary of the Navy, under the direction of the President and in accordance with rules prescribed by Congress. Rules for giving certain types of names to certain types of Navy ships have evolved over time. There have been exceptions to the Navy's ship-naming rules, particularly for the purpose of naming a ship for a person when the rule for that type of ship would have called for it to be named for something else. Some observers have perceived a breakdown in, or corruption of, the rules for naming Navy ships. Section 370 of the FY2021 NDAA (H.R. 6395/P.L. 116-283 of January 1, 2021) establishes a commission regarding the removal and renaming of certain assets of the Department of Defense (including ships) that commemorate the Confederate States of America or any person who served voluntarily with the Confederate States of America."
