Stridsvagn m/42 (Strv m/42) was the first Swedish tank to have a 75 mm gun. It was known as Lago II-III-IV by AB Landsverk. It first entered service with the Swedish army in November 1941 and was designated the Stridsvagn m/42. It was a fully modern tank for its time. It was armed with a 75 mm L/34 gun. It was also well protected and mobile.
The Strv m/42 had its origins on modifications in the Lago (the manufacturer designation) a 16 tons light tank armed with a 57 mm cannon and three machine guns produced for the Hungarian Army in late 1930s by the AB Landsverk, itself a development of the Stridsvagn L-60 light tank also made by the AB Landsverk. The Swedish Army specified for a bigger and better tank than the Lago resulting in the Strv m/42 (later known as Strv m/42 TM), a 22-ton tank armed with a 75mm L/34 gun, suited against armored and soft vehicles, it had similar performance as the German 7.5 cm StuK 37 L/24 gun. The gearbox of the m/42 TM wasn't working well and these tanks were built either as m/42 TH, or they got a new mechanical gearbox and became known m/42 TV.
In November 1941 100 Strv m/42s were ordered. All the vehicles had an electromagnetic gearbox. (Strv m/42 TM, the T meaning two engines and the M meaning electromagnetic gearbox). In January 1942 another 60 Strv m/42s were ordered. This batch were built under license by Volvo, the first 55 vehicles were fitted with twin Scania-Vabis 603 engines and the remaining five were equipped with a new engine, the Volvo A 8B. All the vehicles had the first batch electromagnetic gearbox replaced by a new hydraulic gearbox, with all these modifications, the single-engine vehicles were now designated as Strv m/42 EH, (the E meaning one engine and the H meaning hydraulic gearbox), the dual-engines tanks but with the new transmission were designated as Strv m/42 TH. In June 1942 another 80 were ordered from Landsverk, they were 70 m/42 TH and 10 m/42 EH.
Between April 1943 to January 1945, 282 Strv m/42s were delivered, of which 180 tanks were made in Landsverk, 102 at Volvo. Most of the vehicles, 225 pieces, was fitted with Scania engines. The other 57 tanks got Volvo engines. All of the 225 Strv m/42 TH and m/42 TV produced (all strv m/42 with twin Scania-Vabis 603 engines), were rebuilt between 1957 and 1960 to Stridsvagn 74 tank and the EH vehicles (strv m/42 with single Volvo engine A 8B engines) to Infanterikanonvagn 73 infantry support vehicles. The turrets were reused as static gun pillboxes, along the major coastlines, but mostly defending harbours and more seldom airfields.
Strv m/42 was originally ordered in four versions in three configurations:
- Strv m/42 TM (Lago II) had two engines and electromagnetic gearbox. Made in 1943-44.
- Strv m/42 TH (Lago III), had two engines, each with a hydraulic gearbox. Made in 1944.
- Strv m/42 EH (Lago IV) had an engine and hydraulic gearbox. Made in 1944-45.
- Strv m/42 TV had two engines, each with a hydraulic gearbox. Made in 1948.
The Strv m/42 was issued to the following armored regiments:
- P 1/Enköping - Gotland stridsvagnskompani (English: Gotland tank company),
- P 2/Helsingborg,
- P 3/Strängnäs,
- P 4/Skövde: where the tanks were included in the newly formed tank companies.
The Strv m/42s were employed in the heavy tank companies of the armored brigades. They were phased out of active service in the 1950s and replaced by the Stridsvagn 81.
