The L/60 was produced as a single barrel gun and as a dual gun. The dual gun consisted of a left and right version, mounted side by side and joined in manufacture as a single unit. For field employment, it was extensively produced as a towed gun, though it was also mounted to truck and tank

The Bofors 40 mm
Automatic Gun L/60 was a medium weight anti-aircraft gun that was first released as the model 1934 and then, with only slight modification, as the model 1936. It was the model 1936 that was used for most guns produced during World War II. By 1939, it was in service with 18

ammunition, introduced in the 1970s, increased the effectiveness of the gun in the anti-aircraft role. While the L/70 has never been as prolific as the L/60, it has nonetheless had a similarly enduring service life and been adopted by over 40 different nations.

With the emergence of jet aircraft, the L/60 would become obsolete as an anti-aircraft weapon, but would continue in naval service as the main armament of many small vessels past the turn of the century (2000). The Bofors L/60s have been used in the

chassis. In naval service, it was produced on single, twin and quad mounts, with the quad mounts consisting of two dual guns. Designed as an air-cooled gun, water cooled guns were also produced to improve sustained fire.

model 1948 was of a similar basic design to the L/60 but chambered for a larger, more powerful cartridge. The two main designs have been give numerous designations depending upon their country of service and mounting.

Both the L/60 and L/70 designs have had enduring service lives. Consequently, the generic description of "Bofors 40 mm gun" is insufficient to distinguish the two models without further information.
