Air Burst Munition (ABM)
40mm x 53 Air Bursting Munition for AGL
Summary of Main Advantages
1 Smart technology simple and safe in use
2 No rate of fire limitation due to fuze programming
3 Inductive fuze programming at muzzle (not in the gun)
4 On-line compensation for muzzle velocity variation (optional)
5 Easy system upgrade: minimal weapon modification
6 Absolute gun unload safety
7 Insensitive to mud, humidity & other environmental factors
8 Firing through bushes (impact sensor switched off)
9 If no fuze programming required, self-destruct automatically on
10 Lethality level of each round adjustable

Air Burst Munition (ABM)
40mm x 53 Air Bursting Munition for AGL
Summary of Main Features
Electronic Base Fuze: Ahead technology
Programmable at Muzzle: Fuze time / impact sensor
Arming Time: Mechanically & electronically driven
Safe and Arm: Mechanically driven (Stanag)
Propulsion System: Accurate / low muzzle velocity variation
