The Strv m/42 was introduced during the Second World War as Sweden's primary medium tank. Different versions were developed, however, one of the most experimental ones was the Strv m/42 DT (Delat Torn; "split turret"). Unlike most designs of the time, the new variant used a new turret, with a 75 mm gun and an autoloader. The name comes from the fact that the autoloader forced the turret to be split in half. In 1944, a mockup was made, with a prototype constructed in 1945, however after being tested in different trials in 1946 the design was considered unsuccessful and the project was canceled.

It was introduced in Update 1.97 "Viking Fury". The Strv m/42 DT's most important asset is the reload rate, which can be as low as 3 seconds. The best round available is an APCBC shell that features similar penetration and explosive filler values to other rounds at its rank. The armour is almost non-existent, comparable more to a light tank, and the autoloader makes the tank more vulnerable to ammo detonations, since the ammo racks are more exposed. However, the tank has still a decent mobility to the point it can be used to flank, and the gun depression is also good at -10 degrees.
