# Navy Awards L3Harris Jammer Modification

The U.S. Navy awarded L3Harris an $876.4 million undefinitized modification contract in September 2026 to continue development of the Next Generation Jammer Low Band system through fiscal year 2031. This contract supports both the Navy and the Royal Australian Air Force, with cooperative funding from Australia and work distributed across multiple U.S. states and Australia. It builds on prior engineering and manufacturing development contracts awarded in 2020 and 2024, advancing electronic warfare capabilities by replacing legacy jamming systems on EA-18G Growler aircraft.

- **Why this matters:** The contract represents a significant investment in modernizing electronic warfare systems, signaling ongoing opportunities for defense contractors specializing in advanced jamming technologies.
- The cooperative funding and international collaboration with Australia highlight the importance of allied partnerships in defense procurement.
- Procurement professionals should note the multi-state distribution of work, including locations in Utah, Alabama, and Pennsylvania, which may impact subcontracting and regional industrial base considerations.
- Companies involved in electronic warfare and aircraft systems should evaluate how this extended development contract affects future competitive positioning and technology integration opportunities.
