А190 Naval Gun can fire HE (impact fuze) and AA (time fuze) case ammunitions.
The main advantages of А190 system:
- automatic firing mode with main and back-up control means and the capability to operate in EW battlefield environment;
- minimal dead zones when engaging various target types;
- fast reaction (2…5 sec) to counter air threats. Quick shift of fire when engaging multiple targets.
А190E base variant upgrade comprised the integration of a muzzle velocity radar, instrumentation for checking the alignment between the barrel bore and antenna post axes, the shell feed conveyor reverse feature and stealth cupola. The upgraded version designated as А190-01 provides significant increase in combat effectiveness. High survivability, reliability and combat effectiveness make it possible to operate the gun in various environments day and night all year around. Our engineers managed to minimize the gun mount mass and dimensional parameters and its radar signature. Among other high priority features of А190-01 gun are its large upgrade capabilities, long operational life, security and simplicity of operation. А190-01 on-ship operation lifetime is comparable to the ships' interrepair time.
The gun is also attractive in terms of economic effectiveness due to the low mass production cost per unit, low operation cost and the capability to extend the gun mount in-service time.
Presently, А190 is installed on a number of Russian Navy ships (such projects as 11356, 20380, 20385, 21630, 22356, 22500 etc.) and on several Indian Navy ships.
