According to news reports, the U.S. Army has developed an updated plan to use microwaves to drive drones out of the sky. In a recent public tender, the U.S. Army announced its intention to purchase an airborne high-energy microwave system from Lockheed Martin for use against UAVs. This weapon will be installed on an aircraft and will focus the radiation beam to disable the fixed-wing or four-axis drone.
The latest US Army system uses a similar microwave system developed by Lockheed Martin for the US Air Force. This microwave system is called the "Self-Protection High Energy Laser Demonstrator" or "Shield" (SHiELD). The project won a design award worth $26 million in November 2017 and can also be used to intercept missiles. The bidding document reads: "We are considering the payload of the UAV system, including explosives, fishing nets, tangles/streamers and high-power microwave sources."
After the assassination of Venezuelan President Nicolas Maduro (Nicolas Maduro), drone countermeasures became particularly important. The assassination was carried out by two six-axis drones equipped with remotely controlled explosives. The Venezuelan security forces issued a statement stating that each drone is equipped with one kilogram of C4 explosives. The maximum load capacity of the Matrice 600 is 5.5 kg. In the Maduro assassination, Venezuelan security forces shot down the drone from the air with a rifle, causing the drone to either explode or fall to the ground.
However, there are still more complex and possibly safer countermeasures to choose from. Most drones can be dealt with by target radio interference, which will cause the aircraft to lose contact with the operator and hover over the ground. Other agencies have trained eagles to shoot down drones during flight, although this tactic is still controversial and has not been widely adopted. A recent study by the Bard UAV Research Center (Bard) found that 235 independent anti-UAV systems are being used or are being actively developed.
