USS Minneapolis
Part of the New Orleans-class consisting of the New Orleans, Astoria, Minneapolis, Tuscaloosa, San Francisco, Quincy and Vincennes, preceded by the Portland-class and succeeded by the Wichita. Originally called the Astoria-class but renamed after the losses in 1942 and the following modernisation of the remaining ships. Due to the limited displacement as a result of the Washington Naval Treaty (1922) was she known as a so-called Treaty cruiser classified as light cruiser but later reclassified as heavy cruiser due to the calibre of her main guns. There were three different designs for the ships in this class, namely for the New Orleans, Astoria and Minneapolis (all 3 originally laid down as Portland-class cruisers), the Tuscaloosa and San Francisco and the Quincy and Vincennes.
