China's Navy YJ-20 Hypersonic Missile Completes Final Testing: Strategic Significance of Enhanced Combat Capability of Type 055 Destroyer

The People's Liberation Army Navy of China recently released a strategically significant video through official media channels, showcasing the successful launch of the YJ-20 hypersonic anti-ship missile from the vertical launch system of the Type 055 destroyer, destroying its target. This marks the first public test of the YJ-20 missile on a naval vessel, indicating that this new weapon system, referred to as a "carrier killer" by Western media, is nearing mass production and formal deployment.

In late February 2026, a video released by the Chinese military channel on social media showed the Type 055 destroyer "Wuxi" successfully launching the YJ-20 missile from its vertical launch system (VLS). The video clearly captured crew members reporting via radio, "Missile hit, target destroyed," although specific target information and the test location were not disclosed. This test was officially defined as a "type test"—a decisive evaluation phase in the weapon system's development process, used to verify whether the design meets all operational requirements, serving as the official signal for mass production and deployment.

The YJ-20 missile made its formal debut during the 80th anniversary parade of the victory in the War of Resistance Against Japan held in Beijing in September 2025, showcased alongside the YJ-15, hypersonic YJ-17, and YJ-19 missiles. This signifies China's technological leap in anti-ship missile technology from subsonic to supersonic and then to hypersonic. In fact, as early as 2022 and 2024, the PLA Navy had released videos of what appeared to be the YJ-20 missile being launched from the Type 055 destroyer, but these were not officially confirmed at the time. The formal public type test indicates that the Chinese military has full confidence in the technical maturity and combat effectiveness of this weapon system.

From a technical perspective, the YJ-20 missile represents a significant breakthrough in China's anti-ship missile technology. The missile features a hypersonic glide vehicle design, capable of flying at speeds several times the speed of sound, and possesses maneuverability to change its trajectory, making it difficult for existing shipborne air defense systems to intercept effectively. Compared to traditional subsonic or supersonic anti-ship missiles, the reaction time window for hypersonic missiles is greatly compressed, posing a significant challenge to the defense systems of target vessels. A research report from the U.S. Naval War College estimates the range of the YJ-20 to be between 500-800 kilometers, meaning the Type 055 destroyer can strike high-value maritime targets, including aircraft carriers and amphibious assault ships, from outside the first island chain.

As the primary platform for the YJ-20, the Type 055 destroyer itself is a hallmark of the modernization of the Chinese Navy. This class of destroyer has a full-load displacement of over 12,000 tons, equipped with a 112-cell vertical launch system, advanced phased array radar, and an integrated combat system, and is referred to as a "super destroyer" by the U.S. Navy. Currently, China has built and commissioned eight Type 055 destroyers, with the 9th and 10th undergoing sea trials, and it is expected that by 2027, the centenary of the PLA's founding, the number of these vessels will reach at least 10. Such a scale of construction speed and equipment level makes the Type 055 one of the most powerful surface combat platforms in the Western Pacific region.

The combination of the YJ-20 and the Type 055 destroyer significantly enhances the Chinese Navy's area denial/anti-access (A2/AD) capabilities. In a combat scenario, a Type 055 destroyer equipped with YJ-20 missiles can execute "saturation attack" tactics on the periphery of an aircraft carrier strike group, breaking through the enemy fleet's air defense network with simultaneous attacks from multiple hypersonic missiles. Analysis from U.S. magazine "The War Zone" suggests that the deployment of the YJ-20 will force the U.S. Navy to maintain a greater safety distance in its operations in the Western Pacific, thereby affecting its forward deployment and crisis response capabilities. Particularly in the waters surrounding the Taiwan Strait, this long-range, high-speed anti-ship capability will alter the regional military balance.

From a strategic perspective, the successful test of the YJ-20 missile is closely related to the Chinese military's modernization "2027 goal." According to the U.S. Department of Defense's 2025 report on "Chinese Military Power," the Chinese leadership has set 2027—marking the 100th anniversary of the PLA's founding—as a critical milestone for military modernization, aiming for the integrated development of mechanization, informationization, and intelligence. Against this backdrop, the accelerated formation of new combat capabilities such as hypersonic weapons, fifth-generation fighter jets, and aircraft carrier strike groups is reshaping the military landscape in the Western Pacific.

It is noteworthy that the development and deployment of the YJ-20 missile also reflect China's progress in its military industrial system. From concept design to public display, and then to type testing, the entire process demonstrates the efficient integration capabilities of China's defense industry in developing complex weapon systems. This capability is not only evident in a single weapon platform but also in the collaborative development and operational integration of multiple subsystems, including vessels, missiles, radars, and command systems. A report from the U.S. think tank Center for Strategic and International Studies (CSIS) points out that China is phasing out outdated equipment at a faster pace than the U.S., introducing a new generation of combat platforms, particularly in the naval and air force sectors.

However, the operational effectiveness of the YJ-20 missile system still has some unknown factors. The reliability of hypersonic weapons in target detection, tracking, and guidance in complex electromagnetic environments still needs to be validated through real combat or large-scale exercises. Additionally, how to achieve effective penetration through the multi-layered defense system of an aircraft carrier strike group remains a complex operational issue. The U.S. Navy is accelerating the development of a new generation of air defense missiles and directed energy weapons to counter hypersonic threats, creating a new round of technological competition between anti-ship missiles and fleet defenses.

Overall, the successful type test of the YJ-20 hypersonic anti-ship missile marks a significant advancement in the Chinese Navy's long-range precision strike capabilities. Coupled with the large-scale construction of the Type 055 destroyer and the commissioning of other new combat platforms, China is building a modern naval force capable of executing complex combat missions beyond the first island chain. This not only changes the military balance in the Western Pacific region but also poses new challenges to the maritime strategic deployments of the U.S. and its allies. In the coming years, as more YJ-20 missiles are equipped to the forces and the supporting combat systems are further refined, the Chinese Navy's long-range operational capabilities will experience a qualitative leap.
