20mm/L200 "Screamer" autocannon

BARD PAPER: VERA5013

20mm/L200 Screamer Autocannon

The Screamer is a vehicle-mounted rotary-barrel autocannon, roughly similar as old Solomani Vulcan (PIVAD) air defense gun. Screamer is fully stabilized and computer controlled, and thus it can be installed as a remote mount to any suitable vehicle. While electric action would be much lighter, the recoil-operated Screamer is self- powered, and can also be fired from separate carriage.

The Screamer and two 1200-round magazines can be fitted within 1 m3 volume. Normal ammo mix is proximity-fused HE rounds (HEPX) and contact-fused HEAP rounds.
