  1.  @RedXlV  Armor was left off to stay within 2000 ton - but there "fitted for but not with" their armor belts. When the treaties lapsed, the armor magically showed up and it was installed. There was considerable debate over how r=to arm them. Most wanted 6 inch guns, but there was a group that lobbied for 5/38 dual purpose battery. One of the reasons given to justify this is that they would be useful in protecting Pearl Harbor in case of air attack! Charleston was listed for disposal after WW2 and the USCG requested her to replace the 327 foot cutter Alexander Hamilton, as the 327 footers hull and machinery were based on the Erie Class. Unfortunately, the USCG couldn't raise a crew due to post-war personnel cuts and the Navy got tired of waiting and transferred the disarmed Charleston to the Massachusetts Maritime Academy as its training ship http://www.navsource.org/archives/12/09051.htm

It began on 14 February 1940 and involved the removal of the mainmast which was replaced by a platform with two additional twin mounts for 37 mm anti-aircraft guns and a pair of twin-gun mounts for the 8 mm Mle 1914 machine guns. The rangefinder was moved from the roof of the bridge to the aft end of this platform. Two 25-millimetre (1 in) Hotchkiss AA guns were added on the forward superstructure as were two twin-gun mounts for 13.2-millimetre (0.52 in) Mle 1929 machine guns. Another pair of twin-gun mounts for 8 mm Mle 1914 machine guns were fitted to the quarterdeck. The aft pair of paravanes was replaced by two smoke generators. The ship's anti-submarine capability was increased by the addition of four Thornycroft Mle 1918 depth-charge throwers on the quarterdeck, the installation of a rail for F28 depth charges above the stern and the replacement of the port mine rail by a rail capable of handling two 200-kilogram (440 lb) depth charges. The ship sailed to Cherbourg on 29 May to finish her refit which consisted of the addition of a 4-metre (13 ft 1 in) rangefinder on the bridge roof and the partial installation of a British Type 128A ASDIC. After the fall of France Savorgnan de Brazza received a brief refit there in which her ASDIC installation was completed, the pair of dual-gun mounts for 13.2 mm machine guns forward of the bridge were moved down to the forecastle deck and single mounts for 20-millimetre (0.8 in) Oerlikon guns were installed in their place. In 1942, Savorgnan de Brazza departed Aden on the 11th for an overhaul[20] at the Swan Hunter shipyard in Wallsend, Northumberland.[12] The ship's anti-submarine weapons were replaced by their British equivalent to simplify her logistical requirements and she received the latest small-ship radars to improve her ability to find and sink submarines. A Type 271 surface-search radar was installed on the bridge roof and a Type 286 search radar was also fitted. The aviso was now equipped with two British depth-charge rails, each with space for a dozen depth charges, and four newer Thornycroft depth-charge throwers, each with a ready rack for three depth charges. Oshe was transferred to the South Pacific in March–April. 1944. The ship returned to France to begin an lengthy refit at La Ciotat that lasted from January to October 1945.[ The refit reinforced Savorgnan de Brazza's anti-aircraft armament. The number of 37 mm guns was increased to eight, three 25 mm and two 20 mm guns were added and the number of 13.2 mm guns was reduced to two I wonder if it might been better if they mounted the Heavy AA/Dual Purpose 100mm Mlle 1933 (53 pound shell) instead of the low angle 138.6mm Mlle 1927 with its 88 pound shell. (the US 5 inch Mark 12 fired a 55 pound shell and no one considered that anemic.) but that is probably hindsight
