Design and description

The Ragnar-class destroyer was an improved version of the preceding Wale. [1] The ships normally displaced 350 long tons (360  t ) and 416 long tons (423 t) at full load. They measured 66.1 meters (216 ft 10 in) long overall with a beam of 6.3 meters (20 ft 8 in), and a draft of 1.8 meters (5 ft 11 in). The Ragnars were propelled by two 4-cylinder vertical triple-expansion steam enginess, each driving one three-bladed propeller using steam from four Yarrow boilers. The engines were designed to produce a total of 7,200 indicated horsepower (5,400  kW ) for an intended maximum speed of 30 knots (56  km/h ; 35  mph ). On Vidar's sea trials, she reached 31.3 knots (58.0 km/h; 36.0 mph). The ships carried enough coal to give them a range of 1,400 nautical miles (2,600 km; 1,600 mi) at 12 knots (22 km/h; 14 mph). The ships' crew numbered 69. [2] [3]

The Ragnar's dispensed with Wale's 57-millimeter (2.2 in) M89/B guns in exchange for two additional 75-millimeter (3 in) M/05 guns. One gun each was located at the forecastle and stern; the other two guns were positioned on the main deck amidships, one gun on each broadside. The ships were equipped with two 457-millimeter (18 in) torpedo tubes in rotating mounts located between the rear funnel and the stern gun. Two 6.5-millimeter (0.26 in) M/10 machine guns were added to the ships in 1911–1912 and the single torpedo tubes were replaced by twin-tube mounts in 1916–1917. [2]

Construction and career

Vidar was launched on 6 September 1909 by Kockums Mekaniska Verkstad at its shipyard in Malmö. The ship was commissioned on 14 April 1910. She conducted neutrality patrols during both world wars. [2]
