The ''Tennessee''-class ships were {{convert|600|ft|1}} [[length at the waterline|long at the waterline]], {{cvt|624|ft|1}} [[length overall|long overall]], had a [[beam (nautical)|beam]] of {{convert|97|ft|5|in|abbr=on|1}}, and a [[draft (nautical)|draft]] of {{convert|30|ft|2|in|abbr=on|1}}. They [[displacement (ship)|displaced]] {{convert|32300|LT|t|0|lk=on|abbr=on}} [[standard displacement|standard]], and {{convert|33190|LT|t|0}} at [[full load displacement|full combat load]]. Under emergency conditions, additional fuel and ammunition could be stored, which significantly increased displacement to {{convert|37948|LT}}, which accordingly deepened draft to {{convert|34|ft|9.875|in|1}}.{{sfn|Friedman|1985|pp=443–444}} The ships' [[hull (watercraft)|hulls]] featured a pronounced [[clipper bow]] to handle high seas and reduce spray. A [[double bottom]] extended for the full length of the ships, and their hulls featured extensive [[watertight compartment|compartmentalization]] to reduce the risk of uncontrollable flooding; below the [[waterline]], the hull had 768&nbsp;compartments and another 180 above the line.{{sfn|Cracknell|p=200}}

The [[main deck]], the highest deck that extended for the entire length of the ship, contained much of the living space for their crews,{{sfn|Cracknell|p=201}} which included 57&nbsp;officers and 1,026&nbsp;enlisted men.{{sfn|Friedman|1985|p=443}} As built, they were fitted with two [[lattice mast]]s with [[spotting top]]s for the [[main battery]].{{sfn|Friedman 1986|p=117}} Steering was controlled by a single balanced [[rudder]].{{sfn|Cracknell|p=200}}

The ships were powered by [[turbo-electric drive]]. Eight oil-fired [[Babcock & Wilcox]] [[water-tube boiler]]s generated steam that powered two [[Westinghouse Electric Corporation|Westinghouse]] turbo-[[electric generator]]s that in turn provided power for four [[electric motor]]s that drove four 3-bladed, {{convert|14|ft|adj=on}} [[propeller|screws]]. The turbines were in separate watertight compartments, arranged fore and aft, with four boilers apiece; each boiler had its own watertight [[fire room|boiler rooms]], with two boilers on either side of the turbines. The motors were arranged in three rooms: a larger, central room for the two engines driving the inboard shafts, and one for each outboard shaft on either side. Each set of four boilers was ducted into its own [[funnel (ship)|funnel]].{{sfn|Cracknell|p=201}}

Their propulsion systems were rated at {{convert|28600|shp|lk=on}}, generating a top speed of {{convert|21|kn|lk=in}}. On speed trials, ''Tennessee'' reached a maximum of {{convert|21.38|kn}} from {{convert|29609|shp|abbr=on}}. Normal oil storage amounted to {{convert|1900|LT|0}}, but voids in the hull could be used to increase maximum emergency fuel capacity to {{convert|4656|LT}}. They had a cruising range of {{convert|8000|nmi|lk=in}} at a speed of {{convert|10|kn}}, which fell to {{convert|2500|nmi}} at {{convert|20|kn}} normally; with full emergency oil their range more than doubled, to {{convert|20500|nmi}} at 10&nbsp;knots and {{convert|9700|nmi}} at {{convert|18|kn}}.{{sfn|Friedman|1985|p=443}}{{sfn|Friedman 1986|p=117}}
