Bofors 75 mm and Bofors 80 mm were two closely related designs of anti-aircraft and general-purpose artillery. Less well known than the 40 mm quick-firing AA gun, the gun was nevertheless adopted by armed forces of numerous countries during World War II, including Argentina, China, the Dutch East Indies, Finland, Greece, Hungary, Persia and Thailand. It was closely related to the 8.8 cm Flak 18, one of the best-known AA guns of World War II, which was partially based on it. Some pieces captured by the Japanese in China served as the blueprint for the Type 4 75 mm AA Gun, a reverse-engineered clone of the Bofors 75mm gun.
