| - The ship was powered by four Westinghouse geared steam turbines, each driving one propeller shaft, using steam generated by 12 Yarrow boilers. The engines were rated at and designed to reach a top speed of . At deep load she carried of fuel oil that provided her a range of at a speed of . Milwaukee mounted a dozen 53-caliber six-inch guns; four in two twin gun turrets and eight in tiered casemates fore and aft. Her secondary armament initially consisted of two 50-caliber three-inch anti-aircraft (AA) guns in single mounts, but this was doubled to four guns during construction. Milwaukee was initially built with the capacity to carry 224 mines, but these were removed early in her career to make more space for crew accommodations. The ship carried above-water two triple and two twin torpedo tube mounts for torpedoes. The triple mounts were fitted on the upper deck, aft of the aircraft catapults, and the twin mounts were one deck lower, covered by hatches in the side of the hull. These lower mounts proved to be very wet and were removed, and the openings plated over, before the start of World War II. Another change made before the war was to increase the guns to four, all mounted in the ship's waist. The ship lacked a full-length waterline armor belt. The sides of her boiler and engine rooms and steering gear were protected by of armor. The transverse bulkheads at the end of her machinery rooms were thick forward and three inches thick aft. The deck over the machinery spaces and steering gear had a thickness of 1.5 inches. The gun turrets were only protected against muzzle blast and the conning tower had 1.5 inches of armor. Milwaukee carried two floatplanes aboard that were stored on the two catapults. Initially these were probably Vought VE-9s, but the ship operated Curtiss SOC Seagulls from 1935 and Vought OS2U Kingfishers after 1940.
