New Orleans and
Denver-class "peace cruisers" were reclassified as Patrol Gunboats (PG). On 8 August 1921 the system was revised; the surviving protected cruisers (except for the "semi-armored"
St Louis class) and the peace cruiser/patrol gunboats were all grouped with the scout cruisers as Light Cruisers (CL).

Seattle, was reclassed as IX-39 on 17 February 1941.
Washington Naval Treaty The first cruisers of the
Pensacola,
Northampton,
New Orleans, and
Portland classes – which were designed after the 1922
Washington Naval Treaty, so quickly that the last design was complete before sea trial of the first were finished – were originally designated Light Cruisers (CL) due to their light protection. Later, in accordance with the 1930 London Naval Treaty, they were reclassified as "Heavy Cruisers" (CA) in 1931 due to their guns.
Thenceforward new heavy and light cruisers were numbered in a single sequence. These four classes were known as "Treaty cruisers" and "Tinclads" and were seen even before World War II as deficient by the Navy due to the treaty limitations, but despite their high losses in the early days of the war they performed well. •

London Naval Treaty The terms of the 1930
London Naval Treaty motivated the signatories to de-emphasize heavy cruiser construction in favor of light cruisers. The resultant nine ship
Brooklyn-class of light cruisers had a strong influence on US cruiser design. Nearly all subsequent US cruisers, heavy and light, were directly or indirectly based on them, including the unique heavy cruiser
Wichita. •

Second London Naval Treaty The 1936
Second London Naval Treaty would also influence the Navy's light cruiser program. It imposed limits that resulted in the smaller displacement
Atlanta class with a
dual purpose rapid fire main gun battery, the first such ship in the Navy. •

(CL-54) San Juan (1942) – WW2: 13 battle stars
Cruiser-Destroyer (CLD) Parallel to the
Atlanta design was an abortive attempt to design a super-
Atlanta known as the Cruiser-Destroyer, or
CLD. The "ship characteristics" resulting from this study would be almost identical to that of the later
CL-154 design. CLD did not become an official hull classification symbol.
Early World War II When the United States entered World War II it had three major classes of cruisers under construction: the
Atlanta and
Cleveland light cruiser classes (with 5-inch and 6-inch main batteries, respectively), and the
Baltimore-class of heavy cruisers. The
Cleveland-class was an improvement of the
Brooklyn design, while the
Baltimore-class was an improved
Wichita. These ships would form the bulk of the cruiser war construction effort, with eight
Atlanta-class, twenty-seven
Cleveland-class, and fourteen
Baltimore-class cruisers ultimately completed. Early in the war nine
Cleveland hulls would be diverted for conversion into
light aircraft carriers (CVLs). By the end of the war three
Cleveland hulls would be canceled, and one incomplete hull would later be converted to a
guided missile cruiser. •

Late World War II As the Navy gained experience with World War II combat conditions, it was decided that the
Atlanta,
Cleveland, and
Baltimore classes needed improvement. However, major improvements would cause unacceptable delays in the construction programs. A new generation of cruisers with minor improvements would consist of the
Juneau and
Fargo classes of light cruisers (respectively 5-inch and 6-inch main batteries), and the
Oregon City-class of heavy cruisers. The major noticeable difference would be that the
Fargo and the
Oregon City classes would have their engine exhausts trunked into a single funnel to aid anti-aircraft fire. Due to the near-total destruction of the
Imperial Japanese Navy, the number of the ships of this generation to be completed as gun cruisers would be small: three
Juneau-class, two
Fargo-class, and three
Oregon City-class cruisers. A fourth
Oregon City-class cruiser would be completed postwar as a
command cruiser. Seventeen hulls from among the three classes were canceled. Late in the war the
Baltimore-class would also serve as the basis of the two light aircraft carriers (CVLs). •

Post-World War II The Navy agreed in the waning days of the war to construct a small number of cruisers for the purpose of operationally testing new gun designs and other major improvements incorporating the lessons learned of World War II combat: the 'CL-154' and
Worcester classes of light cruisers (respectively 5-inch and 6-inch main batteries), and the
Des Moines-class of heavy cruisers. Initially the Navy wanted at least one squadron of six ships of each class, but in the end only two
Worcester-class and three
Des Moines-class cruisers would be completed, and the CL-154 class would be cancelled in its entirety. A total of seventeen hulls from among the three planned classes would be canceled. concept •
