Stonewall CIWS

The Stonewall CIWS is a Caliantene close-in weapons system developed and manufactured by Rosseau. It is an autonomous and completely automatic weapon system for short-range defence of ships against highly maneuverable missiles, aircraft, and fast-maneuvering surface vessels.

Development
In 2001, the development of a dedicated CIWS development project was announced by the Caliantene Empire, acknowledging the lack of adequate CIWS systems on the warships of various Caliantene Empire member states. The Stonewall CIWS was unveiled in 1898, with the first iteration using a specially developed 30mm autocannon. Subsequent iterations included mechanical improvements, radar improvements, and increased compatibility with flak and the surface-to-air missiles utilized by the Caliantene Empire.

Operational History
The Stonewall CIWS and its variants have been utilized multiple times during naval exercises and trials. Multiple different targets of various capabilities, including multiple missiles and light unmanned aircraft were effectively engaged and shot down by the Stonewall.
