Northampton class heavy cruisers (1929)
USA (1928-30) - USS Northampton, Augusta, Chicago, Houston, Chester, Louisville
Back to the drawing board
Basically engineers used the previous Pensacola class to start over on a more stable design
USS Northampton 1930
The class in brief
Succeeding the Pensacola, the Northampton improved many points. The very poor behavior at sea was compensated by a raised bow and forecastle, three triple turrets instead of ten in four mixed turrets, an increased width, and lowered superstructures. However, the speed remaining a priority, their armor was sufficient against the destroyers calibers, but apart from 6-in/152 mm shell protection, their subdivision, especially for diving shots, was insufficient. Their class was to include six units built at Newport News and the New York arsenal: Augusta, Chicago and Houston, Northampton, Chester and Louisville.

The class in action (general)
The war quickly imposed the adoption of a DCA more convincing than the single pieces of 127 mm and their carriages of 12.7 mm. One of their TLT tube benches was sacrificed for four 127 mm and 8 mm 12.7 mm pieces in double carriage. Their rear superstructure was remodeled (lower), and from 1943, a new drastic overhaul of the front superstructure, lowered and lightened, but armored. Subsequently, the survivors saw the replacement of their 12.7 mm by quadruple carriages of 40 mm and single 20 mm (in 1944, typically 20 mm and 13-20 of 20 mm Oerlikon). The Houston, Northampton and Chicago will be sunk around Guadalcanal, the Chester badly damaged, the other two will survive and leave the active lists in 1949.
