Abstract: Taking 100 mm antiaircraft gun for example, a barrage fire simulation computing model was established for an air burst antiaircraft gun system. The barrage fire kill probabilities of 100 mm anti?aircraft gun battalion against cruise missile under manual command and C4ISR were calculated respec-tively .The barrage fire kill probabilities were calculated at different intervals oi burst points and trace sample points under C4ISR and compared with those under manual command. The results show that the barrage fire kill probability under C4ISR is six times more than one under manual command. Tnis means the barrage fire under C4ISR is very useful for firing a cruise missile that is difficult to find and track.
