The Strv M/40 light tank was the first Swedish tank to be mass-produced.

Its design was based on that of the Strv L/60 light tank.

The Strv M/40 was a three-man tank, with a 1.46 inch (37mm) main gun and two coaxial 0.315 inch (8mm) machine guns. 

A Scania-Vabis 142 horsepower 6-cylinder engine powered the Strv M/40. It could travel at a maximum speed of almost 30 miles per hour (48.3 kph).

The Strv M/41 light tank had thicker armor than the M/40.  Because the thicker armor made the tank heavier, it needed a more powerful engine. Therefore, the engine was upgraded to a Scania-Vabis 145 horsepower engine.

The Swedish Army used the M/41 until the 1950s. At that time, many Strv M/41 light tanks were adapted for use as personnel carriers.

In 1944, the Strv M/42 light tank entered service. It was the first Swedish tank to have a 2.95 inch (75mm) gun as its main armament.

The Strv M/42 light tank had a crew of four men and weighed 22 tons, more than twice the weight of the Strv M/41.

In the late 1950s, the M/42 was upgraded with thicker armor and a more powerful gun and was renamed the Strv 74. The Strv 74 remained in service until the 1980s.

The M/40, M/41 and M/42 were all built by the AB Landsverk Company.
