Addressing the needs of modern warfare operations，the concept of joint all-domain operations （JADOs） offers a solution by transcending traditional combat domain boundaries.This approach facilitates information sharing，force integration，and coordinated operations among various military branches and operational domains.Consequently，it enhances the operational efficiency，boosts the command agility，and optimizes the resource distribution.The array of benefits delivered by JADOs has shifted the focus towards the research and development of the joint all-domain command and control （JADC2） technology based on the networked information system.This paper offers a systematic analysis on the development history，technical applications，architectural design，and related technologies of JADC2.Meanwhile，the relevant global research status and development trends are examined，with the objectives of providing insights and recommendations to the further progress of the JADC2 technology.
