PRINT DOCUMENT

L-70 Up-gradation is intended to eliminate few of the operational and maintenance difficulties faced in the existing L-70 Gun which is driven by hydraulics. The L-70 upgraded Gun has all electronic drive system along with integrated fire control system to provide an effective, autonomous air defence system and to increase the life span of equipment with low operating maintenance cost. The system has high accuracy with automatic hit point calculation. A very low noise generator provides the silent operational capabilities as against the existing bulky power source.
