Lockheed’s GRIZZLY counter-unmanned aircraft system successfully destroys an attack drone during a live-fire demonstration at Yuma Proving Ground in Arizona, according to multiple outlets. The test integrates the system’s components—radars, the Sanctum software, and a launcher—working together to detect, track, and engage the target. The reports describe the demonstration as a live-fire event in which the system’s sensor and software components are paired with the launcher to carry out the engagement against the drone target. All accounts identify the location as Yuma Proving Ground, and they consistently state that the GRIZZLY system downs the attack drone as part of the demonstration. While the coverage emphasizes the technical integration and outcome, it does not add additional detail in the provided summaries about the drone’s specifications, the engagement sequence, or performance metrics beyond the successful interception. The outlets therefore converge on the same core facts: GRIZZLY uses radar, Sanctum software, and a launcher to defeat an attack drone in a live-fire exercise at the Arizona range.
