Editing Baltimore-class cruiser (section)

===Propulsion===
The ''Baltimore'' cruisers were propelled with [[steamboat|steam power]]. Each ship had four shafts, each with a [[propeller]]. The shafts were turned by four [[steam turbine]]s, the steam produced by four [[boiler]]s, which at full speed reached pressures of up to {{convert|615|psi|lk=in}}. The ''Baltimore''s each had two engine rooms and two funnels, although this was changed in the ''Boston''s, which had only one funnel for all four boilers, as noted above. The high speed was around {{convert|33|kn|km/h}} and the performance of the engine was around {{convert|120000|HP|MW|lk=in}}.

The original ''Baltimore''s could carry up to {{convert|2250|long ton|t}} of fuel, putting the maximum range at a cruising speed of {{convert|15|kn|km/h}} at about {{convert|10000|nmi|km}}. The increased displacement of the modified ''Boston'' and ''Albany'' classes meant their range was reduced to about 9000 and {{convert|7000|mi|km}} respectively, despite increases in fuel capacity to 2600 and 2500 tons.
