Underwater anti-mine technology takes centre stage at Chinese defence show

The Chengdu Defence Technology Industry Expo has put a sharp focus on underwater anti-mine systems, with a range of new equipment drawing attention from military experts and industry insiders. Among the standout displays were submarine-launched drones designed to detect and neutralize sea mines, a persistent threat to naval operations and commercial shipping.

These unmanned underwater vehicles, or UUVs, are built to operate in shallow coastal waters where traditional mine-sweeping vessels often struggle. They can be deployed from submarines without exposing the mother vessel to danger, scanning the seabed with advanced sonar arrays. Once a mine is located, the drone can either mark it for later disposal or, in some models, carry a small charge to destroy the threat on the spot.

The expo also featured new towed sonar systems and autonomous surface vessels that work alongside the drones. One official from a participating state-owned firm noted that the technology reduces risk to human divers and speeds up clearance operations. "Mines are cheap to lay but expensive and dangerous to clear," he said. "These systems change that equation."

China has been investing heavily in naval mine countermeasures, particularly as it expands its maritime footprint in the South China Sea and other strategic waterways. The Chengdu show, held annually, has become a key venue for unveiling such niche but critical technologies. While the event is not as large as the Zhuhai air show, it attracts a focused audience of procurement officers and defense contractors.

The anti-mine drones are expected to enter service with the People's Liberation Army Navy within the next few years, with some prototypes already undergoing sea trials. Analysts say the shift toward unmanned systems reflects a broader trend in global naval warfare, where automation is taking over the most hazardous jobs.
