The Baltimore-class heavy cruisers were a class of heavy cruisers in the United States Navy commissioned during and shortly after World War II. Fourteen Baltimores were completed, more than any other class of heavy cruiser, along with another three ships of the Oregon City sub-class. The Baltimores also were the first cruisers in the US Navy to be designed without the limitations of the London Naval Treaty.
