The Stridsvagn 103 (Strv 103), also known as the S-Tank, is a Swedish post-World War II main battle tank, designed and manufactured in Sweden. Developed in the 1950s, it was the first main battle tank to use a turbine engine and the only mass-produced tank since World War II to dispense with a turret besides the German Kanonenjagdpanzer.[4] It has an unconventional design with a unique gun laying process: it is turretless with a fixed gun traversed by engaging the tracks (like the 75mm gun on the 1930s French Char B1) and elevated by adjusting the hull suspension. An upgrade programme was started in 1986 to fit all vehicles with improved fire control systems. Also, each Strv 103 was fitted with a dozer blade, rather than just one per platoon. A further upgrade in 1987/88 replaced the Rolls-Royce engine with a newer 290 horsepower (220 kW) Detroit Diesel with additional fuel cans placed along the sides to function as applique armour, and added a new laser rangefinder.
