THL 20
20mm TURRET FOR HELICOPTERS
MISSION
When armed with a turreted cannon,
helicopters are provided with a real
air-to-air protection capability as well as a
highly accurate air-to-ground fire support
capability. This significantly reduces
collateral effect risks when engaging ground
targets. The THL 20 turret is designed to
be fitted to attack helicopters and upgrade
helicopters initially dedicated to transport or
observation. This turret is developed around
the 20 M 621 cannon, widely known for its
great versatility and firing the NATO-standard 20mm x 102 ammunition. The THL 20’s highly
reduced integration requirements (weight, overall dimensions, recoil force) and its simplicity
(operation and maintenance) make it a turreted cannon which is ideally suited for upgrading
existing helicopters.
