''Gangut'' was {{convert|180|m|ft|sp=us}} [[length at the waterline|long at the waterline]] and {{convert|181.2|m|ft|sp=us}} long [[length overall|overall]]. She had a [[Beam (nautical)|beam]] of {{convert|26.9|m|ft|sp=us}} and a [[Draft (hull)|draft]] of {{convert|8.99|m|ft|sp=us}}, {{convert|49|cm|ft|sp=us}} more than designed. Her displacement was {{convert|24800|t|ton}} at load, over {{convert|1500|t|ton|abbr=on}} more than her designed displacement of {{convert|23288|t|ton|abbr=on}}.<ref>McLaughlin, p. 207</ref>
''Gangut''{{'}}s machinery was built by the Franco-Russian Works. Ten [[Parsons Marine Steam Turbine Company|Parsons]]-type [[steam turbine]]s drove the four propellers. The engine rooms were located between [[turret]]s three and four in three transverse compartments. The outer compartments each had a high-pressure ahead and reverse turbine for each wing propeller shaft. The central engine room had two each low-pressure ahead and astern turbines as well as two cruising turbines driving the two center shafts. The engines had a total designed output of {{convert|42000|shp|0|lk=in}}, but they produced {{convert|52000|shp|0|abbr=on}} during her [[sister ship|sister]] {{ship|Russian battleship|Poltava|1911|2}}'s full-speed trials on 21 November 1915 and gave a top speed of {{convert|24.1|knots}}.

Her main armament consisted of a dozen [[Obukhovskii 12"/52 Pattern 1907 gun|Obukhovskii {{convert|12|in|mm|0|adj=on}} Pattern 1907]] 52-[[Caliber#Caliber as measurement of length|caliber]] guns mounted in four triple turrets distributed the length of the ship. The Russians did not believe that [[Superfire|superfiring]] turrets offered any advantage, discounting the value of axial fire and believing that superfiring turrets could not fire while over the lower turret because of [[Muzzle flash|muzzle blast]] problems. They also believed that distributing the turrets, and their associated [[magazine (artillery)|magazine]]s, over the length of the ship improved the survivability of the ship. Sixteen [[120 mm 50 caliber Pattern 1905|{{convert|4.7|in|mm|0|adj=on}} 50-caliber Pattern 1905]] guns were mounted in [[casemate]]s as the secondary battery intended to defend the ship against [[torpedo boat]]s. She completed with only a single {{convert|3|in|adj=on|0}} 30-caliber ''Lender'' [[Anti-aircraft warfare|anti-aircraft]] (AA) gun mounted on the quarterdeck. Other AA guns were probably added during the course of World War I, but details are lacking.<ref name=m01>McLaughlin, pp. 220–21</ref> Conway's says that four [[75mm 50 caliber Pattern 1892|{{convert|75|mm|adj=on|sp=us}}]] were added to the roofs of the end turrets during the war.<ref>Gardiner & Gray, p. 303</ref> Four {{convert|17.7|in|mm|0|adj=on}} submerged [[torpedo tube]]s were mounted with three [[torpedo]]es for each tube.<ref name=m01/>
