The tank was to weigh 55 tons and have modular armor for easy upgrading, a front mounted engine, a 14 cm smoothbore autoloaded gun firing APFSDS only. For softer targets than tanks the coaxial 40 mm autocannon firing APFSDS and HE was to be used, or the 7,62 mm coaxial Ksp m/39. The gunner and commander was to sit on the right side of the turret. The tank was of course to have a state of the art C3I-system. The importance of IRV had not been recognized when the study started so instead of an adequate IRV the Lyran illumination round mortars were to used. But the studies had clearly shown that the cost for developing a swedish tank was prohibitive compared to foreign purchase. In 1991 the decision to buy a forign design was taken.
