Stridsvagn 74 (strv 74) was a Swedish tank in use with the Swedish Army from 1958 to 1984. It was a modification of the older stridsvagn m/42 which was phased out of service in the 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 101. The turret of strv 74 was completely new, with a 75 mm high-velocity gun based on an old anti-aircraft gun, engines and transmission were modified or changed from the strv m/42, broader tracks and a separate electrical engine for the turret rotation was introduced while retaining the manual control as a backup.

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 Landswerk for the Hungarian Army.[1] The 74 was therefore in essence a modernized version of the World War II 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 39,700 kg/22.14-tons and powered by a Scania-Vabis 239 kW/320.5 hp diesel engine, 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 three 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.[2]
Stridsvagn 74 was used as a main battle tank in the Swedish Army armoured brigades the first few years until it was replaced by stridsvagn 102 and 103. It was then used in independent corps tank companies, and even later degraded 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.
Strv 74 was available in two almost identical versions, strv 74 H and strv 74 V, the only difference being the transmission. The H version was based on the strv m/42 TH, and the V version was based on the strv m/42 TV. Its high silhouette and thin body along with the recoil of the gun made it wave when firing the gun at 3 and 9 o´clock and it was sometimes referred as "Sanslös" (Swedish for "The Reckless") by its crew.
