China’s Zunyi Destroyer Builds Operational Readiness at Sea

What changed

China’s navy is presenting the Zunyi, its seventh domestically built Type 055 destroyer, as a ship moving from advanced equipment toward greater operational readiness.

Since entering service, the Zunyi has averaged more than 200 days at sea each year and travelled nearly 180,000 nautical miles. Its activities include:

• A 2025 live-fire exercise in the South Pacific
• Anti-submarine training
• Bilingual radio warnings to a foreign aircraft
• Joint exercises with Chinese air and underwater forces

Why it matters

The Zunyi’s story is less about a single dramatic mission than about repetition: long deployments, weapons practice and increasingly complex work with other forces. That is how a modern warship turns sophisticated hardware into a usable military capability.

Anti-submarine warfare is the ship’s central training challenge. Its crew has worked through acoustic theory, consulted engineers and tested new search methods. The account says this produced a multiple-fold increase in target-detection data rates, though that performance claim is not independently verified.

The ship’s annual tempo also shows how China is using its newest destroyers. More than 200 days at sea leaves less room for training to remain theoretical. Crews are expected to operate weapons, change posts and handle complete combat procedures, while practising alongside air and underwater units.

The political message is inseparable from the military one. The Zunyi is named after the city associated with a pivotal moment in the Long March, and its crew repeatedly uses that history to explain endurance, discipline and improvisation at sea. In practical terms, the navy is linking national symbolism to a very modern demand: make a large, complex ship work reliably across sustained and joint operations.
