Does China’s YJ-20 hypersonic sea-based missile give Beijing an edge over US carriers?

China has achieved a major milestone in naval warfare with the mass production of the YJ-20, also known as Eagle Strike-20, the country's first sea-based hypersonic anti-ship missile. Tailored specifically for the People's Liberation Army Navy's Type 055 destroyers—and modified Type 052D vessels—the missile fits seamlessly into the HT-1 vertical launch system (VLS) thanks to its compact dimensions: under 9 metres in length and 850mm in diameter. This allows each Type 055 to carry a significant number of YJ-20s in its 112-cell VLS.

The YJ-20 employs a boost-glide flight regime with a distinctive biconic body design, enabling extreme manoeuvrability at hypersonic speeds. Estimated range is between 1,000 and 1,500 kilometres (621–932 miles), putting most US carrier strike groups within reach from China's coastal waters. The missile combines kinetic penetration with a powerful warhead—a single hit is believed capable of sinking a large surface combatant, including an aircraft carrier. This combination of speed, range, and near-invulnerability to interception gives Beijing a decisive edge over rival navies, potentially shifting the balance of power in the Pacific.
