Bofors 40mm

Bofors 40mm is the collective name for a series of 40mm autocannons produced by Swedish manufacturer Bofors AB (today part of BAE Systems) starting in 1934; the guns were seldom described with a singular name, generally being referred to by Bofors simply as "40mm Automatic Gun" with a series of descriptors detailing the mounting it came with, its intended role, and its barrel length (in calibers, as is convention for cannons - for example, the common L/60 variant has a barrel ostensibly 60 calibers, or 60x40mm = 2,400mm = 1.2 meters long; the "ostensibly" bit refers to how this nominal length includes the barrel and breech together, with the barrel itself being only 56 1/4 calibers long in most cases). The Bofors guns would end up being wildly successful in their primary intended role as AA guns, being used all across the world (in the form of both Bofors-made guns and license-produced foreign copies), and serving on both sides of World War II in a slew of configurations (in both stationary and wheeled ground mounts, on self-propelled anti-aircraft vehicles like the M19 GMC, on submarines and ships in single-, double-, and often quadruple-mounts, et cetera). Post-war, their utility as AA guns would wane as planes began flying faster and higher with each passing year (even with the development of proximity-fuzed 40mm ammunition), though they continue to see use to this day, notably as the main gun of the Swedish CV9040 infantry fighting vehicle, and as one of the 3 principal armaments of the AC-130 "Spooky" gunship.

Mechanically, the Bofors gun is a long-recoil-operated, striker-fired autocannon with a vertically-sliding breechblock, fed by a somewhat unusual system: a 7-round mechanically-indexed magazine (driven by the movement of the barrel and breechblock) is mounted atop the receiver, which can be replenished at any time with either loose rounds or 4-round stripper clips. The theoretical advantage of this system is that it allows for a relatively continuous rate of fire without needing an overly large or bulky feed system (since the weapon can be quickly and easily topped up by its crew, even while it is actively firing); some variants forgo this in favor of more conventional systems, depending on the specific nature of the mount.
