The Stormbringer CIWS is an Illuverendian close-in weapon system introduced in 2046. It is an autonomous and completely automatic weapon system for short-range defence of Royal Illuverendian Navy ships, may it be highly manoeuvrable missiles, small watercraft, aircraft, or fast-manoeuvring surface vessels. The Stormbringer CIWS was initially designed and produced by Takanashi Weapons Laboratory, but after its absorption along the entirety of Takanashi Logistics into Valhallerens Heavy Industries in 2050, VHI facilitates the designing and production of the system.
