The USN came to the conclusion that no 10,000-ton cruiser could adequately perform the roles given. While the Washington Naval Treaty was still being observed, new technology was implemented in the New Orleans class because the USN knew that if and when war came, they would need this knowledge to build ships (which were already in the planning stage) beyond the treaty limits.

From them came the Brooklyn, Wichita, Cleveland, and Baltimore-class cruisers.

This class was the direct ancestor for all subsequent USN gun cruisers. Design #2: Tuscaloosa and San Francisco.Design #1: New Orleans, Astoria, and Minneapolis.Originally called the Astoria class, the class was renamed after USS Astoria was sunk and the surviving ships of the class underwent substantial reconstruction.

The New Orleans-class design was a test bed for innovations in cruiser design, and there were three distinct designs within the class. The four surviving ships were laid up immediately after the end of the war, and sold for scrap in 1959. Collectively, ships of the class earned 64 battle stars. Only Tuscaloosa, which spent most of the war in the Atlantic, got through the war without being damaged. Astoria, Quincy, and Vincennes were all sunk in the Battle of Savo Island, and three others were heavily damaged in subsequent battles in the Guadalcanal campaign. These ships participated in the heaviest surface battles of the Pacific War. The New Orleans-class cruisers were a class of seven heavy cruisers built for the United States Navy (USN) in the 1930s.
