The composition of KM-8 "Edge":
- mortar shot - 120 mm guided mine;
- variable propelling charge;
- automated fire control "Malachite", consisting of a remote control commander and a laser rangefinder-target designator with a thermal imaging type;
- means of communication.
Automated facilities provide the complex with the maximum possible mobility, use in rough terrain conditions - in narrow aisles, with high differences of natural shelters and reverse slopes. With their help, it is possible to fire at selected targets from several mortar guns, which will not cause problems to each other and work on only specified targets. It is possible to apply a complex at any time, day and night. Mortar SAUs can independently target a shot with the help of a laser-type 1-D22 rangefinder, without using automated Malachite tools.
Combat use of the KM-8 "Edge" - firing at any time of day with the defeat of the set goals with the first shot without carrying out sighting shots at fixed and moving targets. The defeat of the following targets located in the 300-m meter zone of the first shot is also carried out at a single firing angle without setting various firing settings in the shot. The KM-8 mobility is due to the specialized fire control automation system, which provides illumination of detected objects in any location, topographic reference with the orientation of the fire fighting system and automatic fire alarm, automation of the calculated actions and installation of the obtained data for firing. In assessing the effectiveness of the combat use of the complex, it was found that using a small number of 120 mm guided mortar rounds, it is possible to hit target targets with great efficiency, while conventional mortar and artillery weapons are already ineffective to fire at targets.
The basis of the KM-8 “Gran” complex is a high-explosive fragmentation mortar shot with a homing head of a 9E430 laser type.
- mortar shot length - 1.2 meter;
- weight 27 kilogram;
- The weight of the warhead - 11.2 kilogram;
- weight of explosive - 5.3 kilogram;
- firing range min / max - 1.5 / 9 kilometers;
- type of warhead - high-explosive fragmentation.
