Bofors 40 mm is an excellent example of technical innovation before the second world war. Bofors developed an excellent medium AA-gun, with využívtím experience with Kruppovými poloautmatickými guns. High speed střílby and the relative good "accuracy" was the key features of this type. When used on ships used the so-called trojaxiální stabilization of the weapons, which means that, for example, the impact of sea waves did not affect the accuracy.

Total licensing production in the US was about 39 200 weapons.
Separate guns mounted on the ships were air-cooled, twins, and quadruplets were chilled liquid ( water).

The maritime versions have been installed, for instance on Polish vessels ORP Błyskawica or ORP Sęp

otherwise trojaxiální stabilize = stabilize in all three axes of movement (for us less technically savvy Wink
