Pensacola

History: The Pensacola class was a class of United States Navy heavy cruiser, the first "treaty cruisers" designed under the limitations set by the Washington Naval Treaty, which limited cruisers to a maximum of 10,000 long tons (10,160 t) displacement and a maximum main battery caliber of 8-inch (203 mm).

In an effort to remain within treaty limits, while still mounting a very heavy main battery of ten 8-inch (203 mm) guns, the hull was of welded construction, and the armor belt was thin (varying from 2.5 to 4 inches (64 to 102 mm) in thickness). This was inadequate to protect her vitals from enemy 8-inch shells and was no thicker than the armor on 6-inch (152 mm) gun cruisers. In fact, Pensacola and Salt Lake City were classified as light cruisers due to their minimal armor until re-designated in July 1931, as heavy cruisers in accord with international practice of designating all cruisers with guns larger than 6-inch as heavy cruisers.
