Armament:

The Ehrensköld class was the first "modern" class of destroyer built by the Swedish Navy after World War I. It introduced several new features mainly heavier armament in three 12 cm guns and the new 53 cm torpedo.

Construction and design

In the early 1920s, the Royal Swedish Navy operated 10 destroyers and 29 first class torpedo boats. The destroyers, which dated between 1902 and 1917, were of similar design, displacing 450–500 long tons (460–510 t) and armed with 75 mm guns and 45.7 cm (18 in) torpedo tubes.[3][4][5] These ships were smaller and less heavily armed than other navy's destroyers, particularly when compared to those of the British Royal Navy and the Soviet Navy.[5]

Nordenskjöld

In 1924, two destroyers of more modern design were laid down, Ehrensköld and Nordenskjöld. The main gun armament was three 120 mm (4.7 in) guns built by Bofors in single mounts on the ships' centreline, with one gun forward, one aft and one between the ships' two funnels, from which it had a restricted arc of fire. Anti-aircraft armament consisted of two Vickers 40 mm automatic anti-aircraft guns.[lower-alpha 1] Torpedo armament consisted of two triple mounts for 53 cm (21 in) torpedoes, while the ships were also fitted for minelaying, being able to carry 20 mines. Three Penhoët boilers fed two de Laval geared steam turbine, generating 34,000 shaft horsepower (25,000 kW) which drove the ships to a speed of 36 knots (41 mph; 67 km/h).[1][6]

The two ships were launched in 1926 and commissioned in 1927.[1]

Operational history

The two destroyers were used to carry out patrols in the Baltic Sea to defend Sweden's neutrality during the Second World War, when the ships' 40 mm Vickers guns were replaced by four Bofors 25 mm cannon in two twin mountings.[1][6]

In 1950–51, the two destroyers were rebuilt as anti-submarine frigates. The aft two 120 mm guns and the torpedo tubes were removed to allow the fitting of an improved anti-aircraft and anti-submarine armament and sensors. As rebuilt, armament was one 120 mm gun, four 40 mm Bofors guns and a single 20 mm cannon. Displacement rose to 1,080 long tons (1,100 t) standard and 1,250 long tons (1,270 t) full load, and speed fell to 30 kn (35 mph; 56 km/h).[1][6][7]

They remained in use until 1963, after which they were used as target vessels. Nordenskjöld was scrapped in 1964 and Ehrensköld in 1974.[1][6]
