US deploys AI-enabled robots for mine clearance in Strait of Hormuz
The United States Navy deployed AI-enabled robots and unmanned vehicles in April 2026 to clear mines from the Strait of Hormuz that reportedly disrupted global energy supplies. The operation uses remotely controlled systems including torpedo-shaped robots and underwater drones to reduce human risk, though experts warned the process would be slow and teams remained vulnerable to attack.
What happened
The United States Navy began a mine clearance operation in the Strait of Hormuz in mid-April 2026, deploying two warships through the waterway alongside remotely controlled robots and unmanned vehicles to detect and destroy mines believed to have been laid by Iran.
The operation employs advanced AI-enabled systems including torpedo-shaped robots called Archerfish, semi-autonomous underwater and aerial drones, and unmanned vehicles with advanced sonar capabilities to replace traditional approaches that relied on human divers.
Reported impact
Experts warned that the mine clearance operation would be slow and complex, potentially taking two to three weeks, and that teams remain vulnerable to Iranian attacks despite the use of remote systems.
The operation was intended to restore shipping traffic through the strategically important waterway, which had been disrupted by alleged Iranian mine-laying that affected global energy supplies following escalated military action in late February 2026.
Index analysis
Former British Navy Admiral John Pentworth noted that mine warfare is effective because the tools are inexpensive to deploy but costly to remove, and even the threat of a minefield is sufficient to halt commercial shipping.
