Taiwan’s Army fired Anduril Industries’ Altius-600M loitering munitions against maritime targets for the first time on June 3, achieving a 100% hit rate during two-day live-fire drills along the island’s northeastern coast in Yilan.

Taiwan’s Military News Agency reported the 21st Artillery Command unmanned aerial vehicle (UAV) battalion completed a full engagement sequence that included aerial loitering, target search, identification, and precision strike. At least three towed flatbed launchers, each loaded with four Altius-600M units, were deployed for the exercise.

The drills, conducted under the Third Theater Command responsible for northern Taiwan’s defense, validated systems that will anchor Taiwan’s planned Littoral Combat Command (LCC), scheduled to activate in July. The LCC will combine Marines, Navy missile brigades, and fast attack craft into a maritime denial force covering waters within 24 nautical miles of the island, with drones central to both strike and domain awareness missions.

The Altius-600M is a 27-pound tube-launched loitering munition, a weapon that circles a target area before diving to strike, featuring a range of up to 100 miles and 1.5 hours of endurance. Its nine-pound warhead fills the gap between Taiwan’s long-range anti-ship missiles and short-range artillery. Taiwan completed delivery of all 291 units under a June 2024 U.S. foreign military sale by March 2026.

The Tianma Exercise coincided with broader anti-invasion maneuvers that included Thunderbolt-2000 Multiple Launch Rocket Systems (MLRS) and M109 self-propelled howitzers deployed on western beaches, while Tianma itself focused on Javelin anti-tank missiles and loitering munitions in the northeast.

Taiwan’s 2025 defense report cited Ukraine’s battlefield drone use to justify expanding its own drone inventory against a potential invasion.

The test is the latest one-way attack drone demonstration along the first island chain. U.S. Army forces fielded one-way attack drones against targets simulating Chinese amphibious vehicles during Balikatan 2026 exercises off the Philippine coast last month.
