Upgrades
Modernization began in 1925 finishing 1927. This included anti-torpedo blisters giving them broader beams, greater displacement and thicker deck armor. Oil-burning boilers were added with a single smoke stack and reduction to a single cage mast. Both were outfitted with newer gunfire controls.
