Definitive BOFORS Akan 40/70B

History & Design


Developed from the original BOFORS Akan 40/60, with a similar internal working system, this gun had a longer barrel, being a L/70 or Length of Calibers 70, this was increased for higher velocity, accuracy. While never receiving the same level of exports or popularity of the 40/60, it was still a solid export, being used by South Korea, Italy, Finland, and a numerous others. Still having a similar mechanical internals, it was greatly enhanced by the Swedish with electronic controls, three banks of eight rounds, still being a recoil-operated auto loading system, it would fire the round when the breech closed. While being the next version of the 40/60, it had a larger cartridge, being the 40 x 365mmR, increasing the breech pressure, muzzle velocity, and accuracy, which led to the extra double vented heat jackets. In the model of the 40/70B, tailor designed for the Strf 9040 B/C, it has the bottom feed, and ejects through the top, using an electronic loader, once the last round in the clip of eight is dispensed, another is loaded from the next clip, and reloading that empty clip, you would select back to that ammunition type, which was displayed on the thermal output screen, however, one round must be fired before the selected ammunition will load. Note: Reload time is game takes longer than real life

An overall very powerful cannon, while having its downsides, it excels in anti-armor and anti-air abilities, taking quite a lead in abilities over other IFV cannons like the Bushmaster Mk.II and III. It’s a versatile weapon, ready to pounce on any target, at any moment, at a moments notice, making it the perfect little pack-a-punch that IFV’s need.
