 All naval Bofors 40 mm L60 guns are virtually identical, the only difference between them being the rate of fire: all single mounts fire at 160 rpm, while twin and quadruple mounts fire at 156 rpm. They all fire the same ammunition from 4-round ammunition clips and have a short enough reload that they can sustain continuous fire as if there wasn't a reload at all. In other words, their cyclic rate of fire (mechanical rate of fire) is the same as their effective rate of fire (rate of fire with reload times taken into account). All naval Bofors 40 mm L60 guns can jam if fired for too long.

These guns fire from a 5-round ammunition clip and have a very quick reload, so their cyclic rate of fire and effective rate of fire are practically identical. They cannot jam.

-One of the best medium-range anti-aircraft cannons in the game, the Bofors L/60 Mark 1 provides very good AA coverage for any ship that it's mounted on. With a 0.0986 kg TNT equivalent explosive charge in each HE round, any hit on an enemy aircraft will usually result in critical damage, if not a kill. The rounds that this gun fires have an above-average muzzle velocity and projectile mass, resulting in a much further effective range than guns of a similar calibre: laterally (i.e. targeting surface targets), the maximum range is about 3.25 km. This is most prevalent on patrol boats and other smaller vessels because it allows those equipped with the Bofors L/60 Mark 1 to knock out enemies safely outside the maximum range of almost every other autocannon (most notably, the German [[2 cm/65 C/38 (20 mm)|2 cm/65 C/38]], which have a maximum range of roughly 2 km).

 Despite the gun's small magazine size of only four rounds, the reload is short enough that there isn't any noticeable difference between its cyclic rate of fire (the rate of fire only considering the mechanical speed of the gun) and its effective rate of fire (the rate of fire accounting for reload times). In other words, it can sustain virtually continuous fire, as if there was no reloading at all. However, this comes at the cost that if fired for too long, the gun can jam. For this reason, it can be advantageous to set the AI gunners to only target aircraft. If allowed to target surface targets, the AI gunners will often waste ammunition on targets well outside of the gun's maximum range, leaving the guns jammed when actually needed.
