When the U.S. military returns to great power competitive strategy and promotes the "Penetrating Counter Air (PCA) aircraft" and "Penetrating Electronic Warfare (PEW) aircraft" projects, from the perspective of military theory, the military requirements and response strategies of all-optical operations are first analyzed. Then, the concept and operational process of all-optical operations are sorted out, and the key technologies of all-optical operations are analyzed. Finally, the future application prospects of all-optical combat links are discussed. Through the analysis of military requirements, the concept of all-optical combat is derived, which will pave the way for the design, development and research of subsequent all-optical combat systems.
