In the 1970s, Swedish engineers developed several original projects, among which was the Lätt Stridsfordon 120. The Bofors engineers meant for it to become a lighter version of the Strv 103. The project was to build a turretless 20-ton tank but with the ability to elevate and depress the gun. Some time later, the military made the final choice in favor of vehicles with fully rotating turrets. The Lätt Stridsfordon 120 project existed only in blueprints.
