Design and description
The Fidonisy-class ships were designed as an improved version of the with an additional 102 mm gun. Kaliakria displaced 1326 LT normal and 1580 LT at full load with an overall length of 93.26 m, a beam of 9.05 m, and a draft of 3.2 m at full load. She was propelled by two Parsons steam turbines, each driving one propeller, designed to produce a total of 29000 shp using steam from five 3-drum Thorneycroft boilers for an intended maximum speed of 33 kn. Kaliakria was designed to carry enough fuel oil to give her a range of 1450 nmi at 16 kn. Her crew numbered 136.

The Fidonisy-class ships mounted a main armament of four single 102 mm Pattern 1911 Obukhov guns. Anti-aircraft defense was intended to be provided by a pair of 40 mm Vickers gun, but these were replaced by two 57 mm anti-aircraft guns in March 1917, and four 7.62 mm Maxim machine guns. The destroyers mounted four triple 450 mm torpedo tube mounts amidships with fourteen torpedoes and could carry 80 M1908 naval mines. They were also fitted with a Barr and Stroud rangefinder and two 60 cm searchlights.
