Oregon National Guard tests drone to remotely deliver explosive during training

Oregon Army National Guard soldiers tested a new method of clearing battlefield obstacles during annual training this week by using a heavy-lift drone to remotely deliver and detonate a live explosive charge.

The proof-of-concept demonstration took place June 22 and was led by soldiers with Bravo Company, 741st Brigade Engineer Battalion, 41st Infantry Brigade Combat Team.

The exercise focused on using an unmanned aircraft to carry a live Bangalore torpedo — an explosive device designed to clear wire obstacles — allowing engineers to breach barriers while remaining farther from potential enemy threats.

Army engineers are responsible for creating safe routes for friendly forces by clearing obstacles such as concertina wire and minefields. Traditionally, placing explosive charges requires soldiers to move close to enemy positions, increasing their exposure to danger.

During the demonstration, a heavy-lift drone carried the explosive charge to a wire obstacle before remotely detonating it, successfully creating a lane through the barrier.

The project was the result of several months of planning by the battalion’s drone working group under the direction of battalion commander Lt. Col. Eric Zimmerman. The unit partnered with Ashland-based Lorica Technologies, which provided the heavy-lift drone used during the demonstration.

Lt. Col. Zimmerman said recent conflicts have highlighted the importance of adapting new technologies for the battlefield.

“Watching what’s happening in Ukraine and seeing how innovative they’ve been inspires you to get better and think bigger,” Lt. Col. Zimmerman said.

The team conducted multiple tests before the live demonstration, beginning with inert training devices before progressing to live explosives. Officials said the final test successfully delivered and detonated a two-section Bangalore torpedo.

Lt. Col. Zimmerman credited the project’s success to collaboration between battalion leadership and the soldiers responsible for carrying out the mission.

“I’m really proud,” Lt. Col. Zimmerman said. “The Soldiers of Bravo Company took an idea from the battalion staff and applied their expertise to make that idea functional and effective.”

Military officials said the demonstration highlights how the Oregon Army National Guard is incorporating emerging unmanned aircraft technology into engineer operations. Lessons learned from the project are expected to help shape future training and the Army’s continued integration of drones into combat engineering missions.

The Oregon Army National Guard is made up of citizen-soldiers who serve part time while maintaining civilian careers, attending school or raising families. In addition to federal deployments, Guard members respond to state emergencies such as wildfires, floods and winter storms when activated by the governor.
