Design and description

Gaidamak displaced 570 metric tons (560 long tons) normal load and 750 metric tons (740 long tons) at full load. She measured 71.3 meters (233 ft 11 in) long overall with a beam of 7.54 meters (24 ft 9 in), and a draft of 2.44 meters (8 ft 0 in).^[1] The ship was propelled by two vertical triple-expansion steam engines, each driving one propeller shaft using steam from three Schulz-Thornycroft boilers. The engines were designed to produce a total of 6,500 indicated horsepower (4,800 kW) for an intended maximum speed of 25 knots (46 km/h; 29 mph). During Gaidamak's sea trials, she reached 25.6 knots (47.4 km/h; 29.5 mph). The ship had enough coal to give her a range 2,510 nmi (4,650 km; 2,890 mi) at 14 knots (26 km/h; 16 mph). Her crew numbered 90 officers and men.^[2][3]

The main armament of the Gaidamak class consisted of two 50-caliber 75-millimeter (3 in) guns, one gun each at the forecastle and stern. Their secondary armament included six 57-millimeter (2.2 in) guns, three on each broadside.^[4] The forward pair was positioned on a sponson at the main deck level below the forecastle, firing through an embrasure. The forecastle was narrowed to allow the guns to fire directly forward. This installation proved to be very wet, especially at high speeds, and made the guns very difficult to work. The other guns were abreast the rear funnel and the mainmast. All of the guns were fitted with gun shields. They were also fitted with four single 7.62 mm (0.30 in) machine guns. The ships were equipped with three 450-millimeter (17.7 in) torpedo tubes in single rotating mounts. The forward mount was located between the funnels while the middle mount was to the rear of the aft funnel and the rear mount was between the mainmast and the stern gun.^[5][6]

In 1910–1911 the ships were rearmed with a pair of 102-millimeter (4 in) Pattern 1911 Obukhov guns that replaced the 75 mm guns. All of the 57 mm guns were removed; the sponsons were removed and the embrasures were plated over. A 37-millimeter (1.5 in) anti-aircraft gun was added and the ships were modified to lay 25 mines.^[6][4]

Construction and career

Gaidamak was laid down on 18 July 1904 by Germaniawerft at their shipyard in Kiel, Germany, and launched on 1 November 1905. She was completed in June 1906 and assigned to the Baltic Fleet.^[1]
