Analysis of Penetration Probability of Ship-Ship Missile in Counter Condition

Based on probability of penetration of ship-ship missile against a naval ship’s defense, the penetration problem of ship-ship missile has been researched under the condition of surface ship formation with various ways against homing missile, and then, the paper establishes the calculation formula of the penetration probability of ship-ship missile. Finally change of penetration probability with change of the number of ship-ship missiles has been given in the formula. Compared the model with penetration probability model of ship-ship missile against a naval ship’s defense, it is more accurate.
