The Vagn Eldledning AutomatKanon (VEAK) 40 (English: "Wagon Fire-control AutoCannon 40") was developed by the Swedish arms manufacturer Bofors, by request of the Swedish army, as a 1960s next-generation Swedish SPAA, following limited production of the Lvkv fm/43 SPAA in the 1940s and the failed Lvkv 42 prototype in the 1950s. A single prototype based on the Strv 103 chassis was built and delivered for testing in 1964. The project was delayed somewhat by this point, but testing commenced regardless, and the vehicle proved to be ahead of its time regarding its armament and fire control systems. This, however, made the vehicle too expensive, and in the end, the project had to be scrapped due to resource reallocation to the Swedish Air Force rather than additional air defences. The name VEAK 40 follows Bofors' own naming scheme, not the Swedish army's naming scheme. Its full historical Bofors-name was Bofors VEAK 40 X 60, VEAK indicating type (tracked vehicle with FC-radar and autocannons), 40 indicating calibre (40 mm), and 60 indicating year of design (1960).

The VEAK 40 was introduced in Update 1.97 "Viking Fury". It is armed with two 40 mm Bofors L/70 autocannons (Swedish designation: lvakan m/48) which each have a fire rate of 300 rounds per minute. It has decent mobility and subpar protection but features excellent vertical and horizontal traverse speed for its guns, giving it fast reactivity to enemy threats. The VEAK 40 also comes equipped with a tracking and search radar that allows the player to find and track airborne targets within a 12 km radius, a big advantage over other SPAAs such as the M163 with only a tracking radar up to ~3 km and the ZSU-37-2 and ZSU-23-4 which have radars that scan the sky extremely slowly on 360° mode, leading to big gaps in awareness.
