100mm A-190(E) Gun

The A-190(E) uses a lightweight gun mount with a 100mm automatic gun and fuze setter. The mounting is fed from separate port and starboard magazines and uses three different rounds: a high-explosive shell with an impact fuze; an anti-aircraft shell using an electronic fuze; and an inert practice round. An automatic control and monitoring system prepares the gun for firing, selects the appropriate ammunition, conducts continuous diagnostics and computes firing corrections. Fire control is provided by the 5P-10E Puma FCS. The gun can fire 60 rounds a minute out to a range of 8.2n miles; 15 km. Weight of each shell is at 16 kg. The A-190(E) gun is based on innovative technological and layout solutions, which features relatively low weight-size characteristics. The gun leads to a more than three-fold increase in the combat effectiveness of surface combatants, as compared to those fitted with the AK-176M gun, owing to increase in the range of fire (roughly twofold); 1.8 times growth in the lethality of projectiles at a target; doubled accuracy of fire; and reduced reaction time as a result of automated operations, such as preparation of the gun for firing, selection of ammunition, monitoring of mechanisms' operation during firing, and display of data on the operator's monitor. The A-190(E) gun is also superior to the AK-100 gun in terms of basic performance characteristics: the rate of fire (approximately 1.5 times greater); accuracy (about three times higher); weight; dimensions; and operating characteristics. The gun also features higher automation of fire preparation and control and employs advanced guided and rocket-assisted long-range and enhanced-lethality projectiles fitted with dual-mode impact / proximity fuses set to operate over the target area. Together with the use of the muzzle velocity meter, it is designed to produce ever increased combat capability of the system in fire against sea- and shore-based point and area targets. In addition, the gun hull features stealth technology to minimize the radar signature of a ship.
