Recently, CCTV disclosed that China's Type 055 destroyer and KJ-600 airborne early warning aircraft have achieved real-time battlefield situation sharing through data links, with the early warning aircraft providing over-the-horizon targets for the sea and air. This also means that early warning aircraft and drones can cooperate with the Eagle Strike-21 hypersonic missile to complete precise strikes at a full range of 1500 kilometers. This technological breakthrough not only marks the maturity of China's military three-service data link system but also indicates that the PLA's joint combat capability has surpassed certain areas of the United States — even within the U.S. Navy’s proud "Cooperative Engagement Capability" (CEC) framework, real-time guidance of cross-service and cross-platform missiles and全域火力 coordination remain unfulfilled goals. In traditional naval warfare, surface warships are limited by the curvature of the Earth, and their detection distance on the sea surface is very limited, sometimes only dozens of kilometers. Over-the-horizon strikes depend on the single platform's target indication ability, easily forming a passive situation where "discovery equals destruction." However, China's breakthrough in the three-service data link has first incorporated space reconnaissance satellites, high-altitude early warning aircraft, drones, surface warships, and fighter jets into the same real-time information network: early warning aircraft act as "air eyes" through wide-area radar scanning, satellites provide global coordinate positioning, drones conduct close-range reconnaissance to dynamically correct parameters, and the Type 055 destroyer transforms into a "sea-based firepower hub," converting the potential range of the Eagle Strike-21 into an actual kill radius through data links. Under this model, the missile achieves a closed-loop kill chain from launch to impact through multi-platform接力guidance, truly realizing the killing chain closure of "A platform detects, B platform decides, C platform strikes." Although the U.S. Navy's Cooperative Engagement Capability (CEC) was proposed in the 1990s, its core remains limited to data sharing between naval vessels and aviation forces, constrained by service barriers and inconsistent technical standards, making progress in cross-service real-time guidance of firepower slow. In contrast, China's three-service data link has unified communication protocols and high-speed interference-resistant transmission,打通ing the "Ren Du Er Mai" of the navy, air force, rocket force, and even space forces. For example, the KJ-600 early warning aircraft can command shipborne air defense missiles to intercept aerial targets or directly guide anti-ship missiles; the Type 055 destroyer can not only receive target data from early warning aircraft but also plan attack routes for fighter groups. This mesh node structure of "platform equality and capability mutual assignment" results in an exponential increase in battlefield resource utilization. The YJ-21, as the world's first carrier-borne hypersonic anti-ship missile, already has a range of 1500 kilometers, far exceeding the operational radius of carrier-based aircraft. The beyond-the-horizon strike supported by data links further compresses the traditional defensive depth of the aircraft carrier strike group to nearly zero — satellite and early warning aircraft construct a real-time updated target database for enemy aircraft carrier coordinates, speed, and routes, allowing Type 055 ships to launch saturation attacks without venturing into dangerous waters; during missile flight, trajectories can be dynamically adjusted based on battlefield changes, leaving conventional interception systems with almost no reaction time against a 6-Mach strike. This "asymmetric killing" mode may force opponents to completely reconstruct their maritime combat system. It can be said that because of the empowerment of the three-service data link, China's aircraft carrier task force has acquired the ability to asymmetrically destroy the U.S. Navy's super aircraft carrier battle group. Overall, the practical application of China's three-service data link represents a military revolution driven by information technology. It breaks down service boundaries and platform function shackles, evolving early warning aircraft, fighters, destroyers, and even satellites from independent combat units into organic components of a "super war system." This全域coordination capability is not only a technical breakthrough but also foreshadows the reshaping of future war rules — whoever controls the high ground of the data link can deliver the "fatal blow" in the fog of war first. For the U.S. military still struggling in the quagmire of service coordination, the PLA's leapfrog development has sounded an alarming bell that cannot be ignored.
