Palma. Naval automatic air defense gun system at close-in defensive lineNaval automatic air defense gun system at close-in defensive line

Provides protection of ships against aerial threats (anti-ship missiles flying at low and ultra low altitudes, cruise missiles, aircrafts, helicopters, guided glide bombs) as well as light-armored surface and coastal targets at close-in defensive line.

Structure principles

• gun system includes two automatic rapid fire six-barrel guns AO-18КD
• specially designed rounds with hard-core tracer bullets made from TNI alloy providing for the assured initiation of the antiship missile warhead
• original multichannel automatic all-weather day / night optronic control system of high precision
• high jamming immunity achieved due to the use of protected narrow-beam optronic channels to acquire and track the target, measure its range and guide the missile onto it
• autonomous target tracking by use of automatic optronic control system with sector coverage and automatic target designation mode
• automatic and semiautomatic target designation modes
• modular-block structure of the system


• high firing capacity
• high effectiveness of combat application including high-speed and low-flying targets
• complete automation of combat processes
• quick response capability (from target detection to fire opening)
• day/night and all-weather capability of combat processes
• concealed fire preparation and high survivability
• radar and optical countermeasure equipments immunity
• high firing rate and capability of quick shifting from one target to another
• high updating potential
