Stridsvagn 74

Stridsvagn 74 (strv 74) was a Swedish light tank^[1] in use with the Swedish Army from 1958 to 1984. It was a modification of the older stridsvagn m/42 medium tank, which was phased out of service in the early 1950s. Instead of scrapping the vehicles altogether, the chassis were used to build a new tank which could be used as a supplement to the newly bought stridsvagn 81. The turret of the strv 74 was completely new, with a 75 mm high-velocity gun based on an older anti-aircraft gun Bofors 75 mm Model 1929, engines and transmission were modified or changed from the strv m/42, wider tracks and a separate electrical motor for turret traverse was introduced while retaining manual traverse as a backup.

History

The stridsvagn 74's development path stretches through the stridsvagn m/40 and m/42 to the original 16,257 kg/16-ton Lago tank, manufactured by the Swedish firm Landsverk for the Hungarian Army.^[3] The 74 was therefore in essence a modernized version of the World War II strv m/42 tank which was itself an attempt to bring Swedish-produced tanks up to the standard of the rest of war-torn Europe. It was most successful in this role.

Produced in 1958, weighing 26,000 kilograms (29 short tons; 26 long tons) and powered by two Scania-Vabis L/607 (170 hp/127 kW each) gasoline engines, the stridsvagn 74 had a top speed of 45 kilometers per hour (28 miles per hour), and a range of 200 km/124.3 miles. With a crew of four, it mounted a 75mm/2.95in main gun and had two machine-guns in its updated turret, which was later further modified with a more sophisticated fire-control type system and an upgrading of the main armament to increase its velocity.^[3]

Use

Stridsvagn 74 was used in the Swedish Army armoured brigades as a replacement for the cancelled purchase of AMX-13 until it was replaced by strv 103. It was then used in independent corps tank companies, and even later relegated to the infantry support role in assault gun companies before being phased out of service in 1981 (strv 74 V) and 1984 (strv 74 H). The turrets were retained and later used as static gun pillboxes, which were phased out and demolished in the early 2000s.

Its high silhouette and narrow hull along with the recoil of the gun made it rock when firing the gun at 3 and 9 o´clock and it was sometimes referred as "Sanslös" (Swedish for "Senseless") by its crew.

Versions

Strv 74 was available in two almost identical versions, strv 74 H and strv 74 V, the main difference being the transmissions which lead to slightly different layout of the interiors. The H version was based on the strv m/42 TH, and the V version was based on the strv m/42 TV.
