Northrop Grumman Unveils Jet-Powered ‘Lumberjack’ Loitering Munition at Modern Day Marine Expo 2025.
‘Lumberjack’ Loitering Munition - Northrop Grumman
Northrop Grumman has introduced its latest innovation in unmanned aerial warfare: the Lumberjack, a jet-powered, modular loitering munition designed for precision strikes, electronic warfare, and reconnaissance. Revealed at the Modern Day Marine expo, the system is poised to redefine tactical flexibility for the U.S. military and allied forces.Modular Design & Capabilities
The Lumberjack falls under the Group 3 UAS category, weighing between 55 and 1,320 pounds (24 to 598 kg) and capable of flying at altitudes up to 18,000 feet. It boasts:
- Speed: 100–250 knots (115–287 mph)
- Strike Radius: Over 200 miles (321 km)
- Loiter Time: Up to 2 hours, depending on configuration
Its modular payload bay allows for rapid reconfiguration, supporting:
- Kinetic strikes with submunitions like the Hatchet glide bomb
- Electronic warfare packages
- ISR (Intelligence, Surveillance, Reconnaissance) missions
Payload & Launch Options
The Lumberjack’s payload capacity rivals the 250-pound Small Diameter Bomb (SDB) class. Its featured munition, the Hatchet, weighs 6 pounds, includes:
- GPS-assisted inertial navigation
- Semi-active laser guidance
- 3-pound high-explosive warhead
Launch platforms include:
- Electric rail systems for naval deployment
- Pneumatic ground launchers for mobile operations
- Air-launch compatibility with platforms like the XQ-58 Valkyrie
AI Integration & Cost Efficiency
Powered by Palantir’s AI and machine learning software, Lumberjack supports:
- Rapid payload integration
- Predictive maintenance
- Reduced operator workload
Estimated at $75,000–$100,000 per unit, it offers a cost-effective alternative to systems like the Hellfire missile, with enhanced modularity and operational reach.
Strategic Implications
With its multi-domain launch capability, precision lethality, and AI-driven adaptability, Lumberjack is positioned to become a key asset in future combat scenarios. Its development reflects the Pentagon’s push for affordable, scalable, and autonomous strike platforms in contested environments.
