RTX’s BBN Technologies secured a contract from the Department of War and the National Spectrum Consortium to develop a smart spectrum manager for the 3.1‑3.45 GHz band, enabling U.S. defense radars to operate safely alongside commercial 5G networks.

The program targets a 50% increase in usable 5G capacity, a 20 dB reduction in radar interference, and a 1,000‑fold improvement in 5G link quality, all achieved by automatically shifting 5G traffic in seconds when radar activity is detected.

This contract is part of the Advanced Spectrum Coexistence Demonstration, a DoD initiative that validates technologies allowing federal and commercial users to share spectrum. RTX’s leadership in this area positions the company at the forefront of a critical capability as 5G expands across the country.

Chris Vander Valk, BBN’s principal investigator, said, "Lives are put at risk when a radar misses a target… our work ensures those radars stay reliable, even as 5G frequencies become increasingly congested," underscoring the national‑security importance of the project.

RTX’s broader defense portfolio has shown strong growth, with Q4 2025 sales rising 12.1% to $24.24 billion and adjusted EPS of $1.55. The new contract adds a revenue stream and reinforces RTX’s strategy to capture opportunities in spectrum sharing and advanced sensing technologies.

The contract value was not disclosed, but the award signals continued confidence from the DoW and the National Spectrum Consortium in RTX’s expertise. The partnership is expected to accelerate deployment of shared spectrum solutions across the U.S. defense network and could open additional contracts.
