Analysis on Antisubmarine Repetitious Attack with Aviation Homing Depth Charges

Aiming at the operational issue of attacking submarine by anti-submarine patrol aircraft with aviation depth charge, a definition of “repetitious depth charge attack”is presented, and the attack occasion and attack parameters are analyzed. Furthermore, attack effectiveness evaluation models of continuous dropping homing depth charges against submarine are established, and the reasonable attack parameters and hit probability are obtained through simulation in the case of submarine taking the countermeasures of maneuver and acoustic decoy. In addition, the repetitious depth charge attack tactics of anti-submarine patrol aircraft are summarized.
