Skyshield is the name given to a Swiss anti-aircraft system developed by the Oerlikon Contraves corporation. The successor to the Skyguard defense system, Skyshield is intended to rapidly acquire and destroy threatening aircraft and missiles.
The weapons system itself consists of two 35mm (1.38 inch) Revolver Cannons with a rate of fire of 1,000 rounds/minute, a Fire Control System made up of a Sensor Unit and a detached Command Post. The Skyshield can also use up to two Surface-to-air missile 8-cell modules for an expanded air defense capability. The Skyshield is designed for traditional anti-aircraft roles in addition to defense against missiles (see Anti-ballistic missile).
