Authorized under the Act of 3.3.1883. 203mm guns were echeloned to port forward and starboard aft, with the end 152mm in the central superstructure counter-echeloned, to permit axial fire of 1 203mm and 1 152mm fore and aft. They were much too slow to be effective cruisers, and the partial deck gave very inadequate protection. Sail, in the form of a brig rig without royals or head gear, was later removed.
A 38mm deck extended for 30.5m over the machinery spaces, and 203mm guns had a 51mm barbettes and later received shielded mountings.
From November 1905 Atlanta served as an accommodation ship for torpedo boat crews, while Boston acted as a training ship for the Oregon Naval Militia from June 1911 to September 1916, served as receiving ship at Yerba Buena from 1918 to 1946, and renamed Despatch in August 1940.
