The
Hugin-class ships were improved versions of the earlier and were the first Swedish warships built with
steam turbines. The ships
displaced at normal load and at
full load. The destroyers measured
long at the waterline and
overall with a
beam of and a
draught of at normal load. The
Hugins were powered by a pair of
AEG-Curtiss
direct-drive steam turbines, each driving one
propeller shaft using steam provided by four
coal-fired
Yarrow boilers. The turbines were designed to produce a total of for a maximum speed of . Both ships handily exceeded their designed speed with
Hugin reaching and
Munin . They carried enough coal to give them a range of at a speed of . The ships had a complement of 73 officers and
ratings. The guns fired shells at a muzzle velocity of . The ships were also armed with two 457 mm (18 in)
torpedo tubes on single mounts located on the
centreline between the stern gun and the
funnel.
Modifications The ships exchanged their single torpedo-tube mounts for twin-tube mounts in 1916 and
Munin had her
bridge elevated four years later. Both ships replaced their stern gun with a pair of twin-gun mounts for Bofors 25 mm M/32|
Bofors anti-aircraft guns in 1939. They also had a pair of depth charge racks added at the stern.
Hugin was reboilered in 1941–1942 and had her guns replaced. ==Construction and careers==
