Modernization Package ARM-28 for ZU-23-2 autocannon
The modernization, the autocannon gives it the new innovative features. Thanks to controlled digitally electric drives (with emergency manual drive) it is possible to achieve both precise guidance and high-speed gun movement.
Electromechanical Equipment ARM-28 cooperates with modern optoelectronic sights
that allow shooting with both traditional ammunition (HEI-T, APIT) and modern
sub-caliber ammunition APDS-T. Electromechanical Equipment can be integrated with
surface homing surface-to-air missile (SAM) mounted on a cannon.
Resistance to environmental factors
| Storage ambient temperature | -40oC to +65oC |
| Operating ambient temperature | -30oC to +50oC |
| Sinusoidal vibration resistance | 50 m/s2 for 5 ÷ 500 Hz |
| Resistance to multiple mechanical strokes | 150 m/s2 for 5 ÷ 15 ms |
Modernisation Scope
- electric drives for azimuth and elevation
- operator’s control panel and joystick
- sensors to measure rotation and elevation position
- sight 2C27 replaced with the electronic sight
- electric Drive Control Unit
- autonomous power supply
Modernization allows for programming of forbidden zones in azimuth
and elevation, autocannon operation modes – manual, semi-automatic and automatic, as well as for the crew number reduction from 5 to 4 operators.
