Abstract: This paper analyzes the development trend and the key to success of Penetrating Counter Air(PCA) combat in the future, aiming at the two remarkable characteristics of PCA full platform stealth and distributed killing. Firstly, based on the organic integration and complementary advantages of two fire control modes, " target-centered all-aspect attack " and "all-aspect attack of the launch platform", under the full-time airspace framework of before and after shooting, covering multi-aircraft, multi-missiles and multi-targets. The concept and design principle of Penetrating Counter Air all-domain fire field reflecting the dynamic and comprehensive lethality performance of multi-fire nodes of coordinated air combat from a global multi-level perspective was proposed, and the time-varying lethal performance model of air-to-air missiles based on the acquisition probability and its full-probability formula was redefined. Based on this, a sin-gle-machine fire field model and a dual-machine fire field aggregation model are established. Secondly, by introducing the three physical concepts of "gradient, divergence and curl" of field, the characterization model of space distribution, action range and deflection change characteristics of fire field is established respectively, and the corresponding simu-lation and characteristic analysis of fire field are carried out. Finally, two typical air-to-air combat tactical scenarios of applying the all-domain fire field to OODA (observation-positioning-decision-action) closed loop fire control aiming and manipulation, single-aircraft stealth penetrating and two-aircraft coordinated attack are preliminarily explored. It is proved that this new fire control principle possess good technical advantages and application potential. The above research work plays an important role in giving full play to the performance of new weapons and equipment, effective-ly improving the capability of free attack and free escape, and improving the effectiveness of air combat. At the same time, it can provide theoretical support and technical reference for the agile construction of distributed kill net, dynamic combination of killing chain and analysis of new tactical methods.
