The Bahman seems to equipped with a modified turret of Soviet-made ZSU-57-2 self-propelled anti-aircraft gun. Main armament consists of twin 57mm S-68 guns which have the same performance and use the same ammunition as the towed single S-60 anti-aircraft gun. The turret is mounted at the rear of the truck chassis.
The turret has an elevation an elevation of +85º, depression of -5º and 360º turret traverse. Elevation, depression and turret traverse are powered, with manual controls available for emergency use.
The original Soviet-made ZSU-57-2 has a rate of fire of 105 to 120 rds/min with a practical rate of fire of 70 rds/gun/min. Maximum horizontal range is 12,000 m, maximum vertical range 8,000 m,
although effective ranges are less than this. Effective slant range is 3,993 m, effective altitude limit with weapons elevated at +45º is 2,835 m and effective altitude limit with weapons elevated at +65º is 4,237 m.
In firing position, the vehicle is stabilized by the use of two large hydraulic spades lowered on the ground on each side of the turret.
Very good new for Iran.
The Bahman should be considered as the masterpiece of Iranian air defense, beside their Bavar, S-300, Yahzarah, etc....
The greatest avantage of Bahman is not vulnerable to Jam, but the challenge is to forbid the altitude below 10.000 m. 60 years after the legend of S-60, the Bahman is now the best candidate. However in that time, the S-60 was effective until 6.000 meters altitude, for that reason, US lost several thousands of airplanes, then the S-60 contributed in significative way to the US defeat in Vietnam war. I notice too that the data available at armyrecongnition are not always reliable. How can they claim these assertions

when they did not inspect this hardware, they have no clues, but they speculate about unknown datas. The S-60 was designed during the fifties, now we are near 2020. With the 3D priting -Iranians are among the best in this area-, computer design etc...it is obvious that the balistic made a huge progress, as the guidance.
The Bahman should have a passive systems that could detect enemies at least 40 km -if not more-, the vertical range should overpass 10.000 meters to reach around 12.000 meters, for that reason the Bahman is extremely redoubtable against any western aircraft, and in a case of war this hardware will undoubtly nullify -as it is usual in all western air campaign- all US air bombing. The Hezbollah milice should possede this hardware too hence, it represents a crucial step for Lebaneses air defense.
Moreover, Russia is preparing too another successor to the S-60, it is names ZAK-57

The vertical range should exceed 10.000 meters too. The anti aircrafts guns are not dead, they won't be replaced by missiles, because they are more reliable.
