Accelerator Autocannon

Space Marines Portal

Accelerator Autocannons are a type of heavy Autocannon. These rapid-firing weapons fire shells at a much higher velocity than a standard Autocannon, enabling them to successfully engage moving targets and strike with pinpoint accuracy.^[1] It is technologically akin to heavier calibre ordnance mounted on the Fellblade,^[3a] and are magnetically charged.^[3b] A rapid-fire version was also mounted on the Araknae platform.^[4]

A smaller version of these weapons are used by Primaris Vanguard Suppressors.^[2]
