The Bofors 57 mm m/54 was a wheeled automatic anti-aircraft gun for land based use produced by Bofors and developed from the similar Bofors 57 mm m/50 naval artillery gun. The gun was developed in the 1950s and fielded by the Belgian and Swedish forces. In Swedish service, the gun was known as the 57 mm lvakan m/54. The m/54 fired a 2.67-kilogram high explosive projectile at a muzzle velocity of 880 meters per second and a rate of fire of 160 rounds per minute. Weighing in at 8.1 tons, the m/54 had an effective range of 4,000 meters. The ballistics of the m/54 at practical air defense altitudes were not particularly superior to those of the Bofors 40 mm AA gun, resulting in relatively few sales of the m/54.
