"Skyshield" is a short-range air defense system developed by the Swiss company Oerlikon Contraves.

[Skyshield] Air-defense system is a modular, lightweight, Short Range Air Defense (SHORAD) system developed by the Swiss company Oerlikon Contraves (now a subsidiary of Rheinmetall from Germany). The successor to the Skyguard defense system, Skyshield is intended to quickly acquire and destroy aircraft and missiles.

The weapon system itself consists of two 35 mm (1.38 inches) revolver cannons with a firing rate of 1,000 rounds per minute, a fire control system consisting of a sensor unit and a separate command post.

I got this text from Wikipedia

control:

•vtol: for left and right 90 °.
•trim up: weapon that rises to the top (sorry if it's not clear).
•1: turning backwards

note:

advantages:
Skyshield can also use up to two surface-to-air 8-cell module missiles for expanded air defense capabilities. Skyshield is designed for the role of anti-aircraft in addition to defense against missiles(if your skill is pretty good)

disadvantage:
if the plane is small, fast and not visible. maybe this is his weakness
