Bofors Naval Variant
40mm Bofors - Naval Variant
Introduction The Swedish designed "Bofors" gun is probably the most recognizable medium anti-aircraft gun in the world. Almost every country has fielded a Bofors gun of some variant, and all of the worlds' major navies used these guns during World War II. Originally designed in 1933, the model 1936 variant was approved for production and purchased by many European countries. Great Britain and the Commonwealth nations produced over 2900 units, and the United States produced a staggering 31,900 for it's navy. The Germans and Japanese created their own versions, although they were produced in smaller numbers. The Bofors anti-aircraft gun was situated in single, double, and quadruple mountings for ships. Today the Bofors is still in use with many countries and their navies, and is even mounted on modern aircraft.
