The HD-1 is an anti-ship and land-attack cruise missile developed by the People's Republic of China. This missile is used by the People's Liberation Army Navy. Introduced at DSA 2024, the HD-1 combines advanced capabilities, particularly in terms of speed and range, to meet various military needs.

This missile has a launch mass of 2,200 kg and measures 8.3 meters in length with a body diameter of 0.375 meters. It is capable of carrying a payload ranging from 240 to 400 kg, including options for unitary or cluster munitions. The HD-1 is powered by an integrated ramjet engine with a solid rocket booster, enabling it to achieve impressive speeds between Mach 2.5 and 3.5, which is approximately 2,716 to 4,321 km/h.

The operational range of the HD-1 is 290 km, with the ability to fly at a cruise altitude of 15 km and descend to between 5 and 10 meters above the ground or sea during an attack, thus increasing its stealth and survival capabilities against enemy defenses. The missile utilizes an inertial navigation system coupled with satellite guidance for navigation, and it is equipped with radar and infrared guidance for terminal guidance, significantly enhancing the accuracy of the attack.

Finally, the HD-1 can be launched from various platforms, including aircraft and ships, thus offering considerable flexibility in deployment options and use according to tactical requirements. This versatility makes the HD-1 a valuable tool for Chinese maritime and terrestrial military operations.

The HD-1A, primarily for aerial deployment, is equipped with an infrared imaging sensor and an inertial navigation system with GPS update, achieving an approach accuracy of 20 meters, reduced to 10 meters when using its infrared seeker (IIR). The HD-1C variant, suited for anti-ship operations, features an active radar seeker that improves the probability of a single-hit kill against moving naval targets to 75%.

The showcase at DSA 2024 not only highlighted the missile's specifications but also emphasized its modular design, allowing for various launcher configurations. This flexibility makes the HD-1 adaptable to multiple platforms and mission requirements.
