Portland-class Cruiser

The Portland class of heavy cruisers consisted of two ships built for the United States Navy in the 1930's: USS Portland and USS Indianapolis.

Originally ordered as Northampton class ships in the early 1930s, these cruisers used the same three triple-turret layout for their 8-inch (203 mm) guns, but mounted twice as many 5-inch (127 mm) guns (8 vs 4), and were somewhat heavier. They were redesigned as a result of the original Northampton's being nearly 1,000 tons below the treaty limitations. Since they were built in commercial ship yards, they could not be redesigned to the extent of the follow-on New Orleans class. Instead they were given moderately thicker belt armor and a heavier secondary armament, although they deleted torpedo tubes and the bulbous bow. The Portlands were followed by the New Orleans class.
