Self-propelled artillery mounts 2 S3 "Acacia" have been in service with the Soviet and then the Russian army for 44 years. They will be the first to be replaced by the new Coalition SV 2S35 super self-propelled guns. The latest to retire will be the modernized 2S3M2 self-propelled guns, which, in terms of their combat intelligence, can compete with many foreign artillery systems.
Externally updated "Acacia" looks almost the same as its older versions. This is all the same 152-mm howitzer 2А33М, the range of which with a conventional high-explosive fragmentation projectile reaches 17,4 km, and active-reactive ammunition - up to 20,5 km. Ammunition - 46 shots.
The rate of fire is up to 4 shots per minute. Reservations - up to 30 mm. Engine power - 520 HP Maximum speed - up to 60 km / h. Power reserve - up to 500 km. Its weight is 27,5 tons. Crew: 4 man.
The difference is in the well-developed “intellect” hidden inside the car.
These peculiar "electronic brains" self-propelled guns were called ASUNO-automated guidance and fire control system.
This system, equipped with a digital ballistic computer, provides unprecedented automatic guidance at any time of the day. It enables the processing and storage of information on 10 fire missions, as well as the transfer of reports to the control machine. There is a modern satellite navigation system. The presence of a special antenna in the back of the tower indicates its presence.
Vehicles can arbitrarily disperse into a firing position, which significantly removes the risk of being hit. ASUNO devices are available both for the commander of the vehicle, and for the gunner and loader.
Due to the presence of ASUNO, the old woman "Acacia" got a second life. With its help, the self-propelled gun not only surpasses, as they say, "on the head" similar machines that are in the armies of the countries of the former post-Soviet space, but can argue on a number of characteristics even with modern NATO ACS.
