Here's the New Marine Corps Weapon that Just Destroyed an Iranian Drone

The Marine Corps' Light Marine Air Defense Integrated System, known as LMADIS, jammed an Iranian drone that President Donald Trump said flew within 1,000 yards of a Navy warship in the Strait of Hormuz, a defense official said. The official spoke on the condition of anonymity due to the sensitivity of the mission.

The California-based 11th Marine Expeditionary Unit deployed to the Middle East with the LMADIS, the defense official said. That unit, which includes about 2,200 Marines, is currently on a six-month sea deployment with the Navy's Boxer Amphibious Ready Group.

Marine jamming jeep sends unknown drone to the deep

The incident is just 28 days after Iran shot down a Global Hawk over the Strait of Hormuz. While the drone jammed by the Boxer has yet to be identified, Iran has drone bases in the area (which is, again, a narrow body of water that borders Iran, and over one side of which Iran claims sovereignty). Non-state actors have also operated drones in the surrounding area, sometimes supplied by regional powers. The downing of the Global Hawk almost risked escalation, though the uncrewed nature of drones versus the certainty of human casualties in the event of a retaliation appears to have calmed tensions.

Instead, the recent exchange of attacks on drones hearkens back to an earlier era of tension in the Strait, invoking the attacks on commercial vessels during the Iran-Iraq war which ultimately involved US naval patrols and is recorded in history as the Tanker War. Jamming drones, in theory, poses less of a risk to other commercial or otherwise peopled aircraft, but the likely consequence of the exchange of drone destruction in the summer of 2019 is that commercial aircraft will steer clear of the area. After all, the greatest tragedy of the Tanker War involved a U.S. cruiser mistaking a civilian Iranian airliner for an attacking jet fighter, leading to the deaths of 290 people.

It is also worth noting that the immediate answer to a drone threat to ships appears to be simply parking a ground vehicle carrying a counterdrone system on the deck. The counterdrone field is full of possible solutions, but most have focused on either facilities or dismounted patrol protection, looking at handheld devices or larger installations at fixed points at bases. There is likely an underserved market in counterdrone solutions for ships, especially aimed at stopping mid- to low-end fixed-wing craft.

Update: US says it destroys Iranian drone “threatening” navy warship
19 July 2019

The Pentagon confirmed the confrontation but did not acknowledge the unmanned aerial vehicle?s (UAV's) destruction.

"At approximately 1000 local time, the amphibious ship USS Boxer was in international waters conducting a planned inbound transit of the Strait of Hormuz," Pentagon spokesperson Jonathan Hoffman said in a statement. "A fixed-wing unmanned aerial system [UAS] approached Boxer and closed within a threatening range. The ship took defensive action against the UAS to ensure the safety of the ship and its crew."

News outlets CNN and NBC reported the UAV was brought down by electronic jamming. NBC attributed the action to the 11th Marine Expeditionary Unit rather than to ship's countermeasures.
