Lumberjack is a modular, launch-agnostic platform capable of being deployed from land, air or sea. Northrop Grumman positions it as a scalable, cost-effective solution that addresses the evolving needs of modern defence operations.
The UAS is equipped with electronic warfare systems, a visual positioning system, and beyond line-of-sight (BLOS) satellite communications. These features enable operations in environments with disrupted, degraded, or denied communications, including areas with limited GPS access.

With a take-off weight of approximately 131 kilograms and a core structure weighing just 36 kilograms, Lumberjack is compact yet capable. Measuring 1.8 metres in length, 0.36 metres in width, and 0.25 metres in height, it can operate from a variety of mobile and stationary platforms.
The aircraft reaches speeds up to 230 knots, or roughly 425 kilometres per hour, at altitudes around 6,000 metres. Despite these ISR-class performance levels, its logistics and operational costs remain significantly lower than conventional systems.
Its modular architecture allows for rapid reconfiguration with both kinetic and non-kinetic payloads, including surveillance sensors and electronic warfare tools. Northrop Grumman emphasises that Lumberjack is not a traditional reconnaissance drone or loitering munition, but a flexible, multi-role platform.
“Lumberjack exemplifies the strength of collaboration,” the company stated, highlighting its work with “non-traditional partners” to deliver an “affordable, low-risk, ready-now solution.” The open systems architecture also supports fast hardware and software updates and integration of AI and machine learning technologies.
The programme has already reached Technology Readiness Level 6, meaning it is ready for operational testing in realistic conditions. Northrop Grumman stresses the platform’s adaptability as a force multiplier capable of extending mission reach while preserving manned assets.
In a recent social media post, the company reiterated: “We’re fast-tracking innovation with Lumberjack™! In less than 14 months, this scalable and launch agnostic Group 3 UAS, went from concept to flight-tested, reinforcing our commitment to delivering advanced capabilities with speed.”
With its compact design, high-speed capabilities and adaptable payload configurations, Lumberjack is designed to meet the growing demand for survivable, versatile UAS solutions in contested environments.
