— The first version of ACS — D-80. It was supposed to establish a tool for chassis ZIL-135L. Was located above the cab chassis of the rotating spetsmagazina 4 of ammunition for guns with muzzle loading side. Provided a massive gun barrel with a muzzle brake, whose efficiency was 58 percent. The breech of the gun rested on the ground baseplate (mortar type execution). Exactly the same chassis had SDA D-110K from OTP "Onega". The gun recoil mechanism was provided with a longish stroke recoil. Loading and discharge occurred with spetsustroystva. Loading the split type — was the first round, followed by expelling charge type. Guidance produced by a hydraulic device, powered by the main engine. Was also hand-drive type. The iron sight is taken from the 122-mm howitzer D-30. For the transportation of ammunition to the ACS planned to make the transport charges the car, on the same type chassis. The car was supposed to provide transportation to deliver 11 Arsova.
— Length — 12.5 meters;
— width — 3.2 m;
— height of 3.7 meters;
— speed up to 60 km / h;
— Second version of ACS — D-80S. The gun mounted on the chassis of the crawler-type MT-T. Option proposed by the Kharkov plant engineering. The gun breech-loading performance of the ACS.
— The last option ACS — D-80-2. Gun is MT-LB chassis. Gun without a massive muzzle brake fire must be applied at the bottom of the fence to the ground ACS. Recoilless cannon made by the scheme, the breech of the gate was a strong emphasis on the creation of a modern PTRC poddon.No "Point", which completely puts an end to the project 535 mm self-propelled guns.
