Northrop Grumman demonstrated its Lumberjack uncrewed aircraft system during the US Army’s Operation Lethal Eagle exercise, showcasing advanced autonomous mission capabilities. The system successfully performed fully autonomous operations, precision strike simulations using the Hatchet munition, AI-assisted targeting, and beyond-line-of-sight communications, while seamlessly shifting to surveillance roles.

The Lumberjack UAS is a modular, low-cost Group 3 uncrewed aircraft designed for flexible, multi-mission operations. According to its datasheet, it is an “attritable” system—built to be expendable—while offering both kinetic (strike) and non-kinetic (electronic warfare, ISR) capabilities through interchangeable payloads.

The platform can be launched from air, ground, or sea and supports beyond-line-of-sight communications, enabling operations in contested environments. Its open architecture allows rapid integration of new technologies and third-party payloads, while its relatively lightweight design (around 290 pounds gross weight) and transportability support quick deployment and scalability.

Overall, Lumberjack is designed to deliver affordable, adaptable, and autonomous combat power, acting as a force multiplier for modern military operations.
