Unsatisfied with the destroyer leader, the Soviets decided that they needed foreign design assistance around 1934–1935. The French were not willing to share ship plans so the Soviets turned to Italy, based on their earlier experience with the Italians during the preliminary design work for the s. They requested designs for a high-speed destroyer leader from three Italian shipbuilders and accepted the submission by
Odero-Terni-Orlando (OTO) in September 1935. They would build the lead ship, named
Tashkent, in their
Livorno shipyard, and provide assistance for the Soviets to build others in their own shipyards. Three other ships were ordered, although the only ship to receive a name was
Baku, before they were all cancelled due to difficulties with adapting the Italian design to Soviet shipbuilding practices. A total of eleven ships in the class were planned: three for the
Baltic Fleet, two for the Black Sea Fleet, two for the
Northern Fleet and four for the
Pacific Fleet. The
Tashkent-class ships had an
overall length of , a
beam of , and a mean
draft of . The ships displaced at
standard load, at
full load, and at
deep load. Their crew numbered 250 officers and sailors. The ships had a pair of geared
steam turbines, each driving one three-bladed
propeller using steam from a pair of
Yarrow boilers that operated at a pressure of and a temperature of . The ships had a maximum capacity of of
fuel oil which gave them a range of at a speed of . They were equipped with a pair of
turbogenerators and three
diesel generators, two of and one of .
Armament and fire-control Tashkents main armament was intended to consist of six 50-
caliber B-13 guns in three twin-gun
B-2LM turrets, one
superfiring pair forward of the
superstructure and the other mount aft of it. However, the turrets were not ready in time so three single mounts were substituted.
Anti-aircraft defense aboard
Tashkent was designed to be provided by four 46-caliber semi-automatic
21-K AA guns in single mounts, but six weapons were actually installed, all of which were clustered around the aft
funnel as well as six
DShK machine guns. The
Tashkents carried nine
torpedo tubes in three rotating triple mounts
amidships. The ships could also carry 76
mines and 24
depth charges which were delivered by two throwers and one stern rack.
Modifications During a brief refit in February 1941, the three B-2LM turrets were installed. At the same time the 45 mm guns were replaced by an equal number of fully automatic
70-K AA guns. The 34-K guns could elevate between -5° and +85° and had a rate of fire of 15–20 rounds per minute. Their muzzle velocity of gave their
high-explosive shells a maximum horizontal range of and an effective ceiling of .
