The Bofors L/60 Gun was a light 40-mm anti-aircraft gun designed by the Bofors company of Sweden in 1929 and used by almost all combatants in the Second World War. They were highly effective against low-flying ground attack aircraft. The original models were entirely hand operated and visually sighted, but in the latter part of the war radar predictors and power control were added, improving the chance of hitting the target. It fired from four-round clips at a rate of 120 rounds-per-minute and had an effective ceiling of 1520 metres and a muzzle velocity of 823 meters-per-second. Research Bofors
