The Bofors 57 mm m/54 (57 mm luftvärnsautomatkanon m/54 or 57 mm lvakan m/54) was a wheeled[3] 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 both the Belgian and Swedish military.
The m/54 fired a 2.67kg (05.89lb) high explosive projectile at a muzzle velocity of 880m/s and a rate of fire of 160 rounds per minute. Weighing in at 8.1t, the m/54 had an effective range of 4000m (13,000feet).[4] 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.[5]
