Raytheon, a unit of RTX (NYSE: RTX), delivered its second sensor payload to Lockheed Martin for the U.S. Space Force's Next-Generation Overhead Persistent Infrared Geosynchronous Earth Orbit Block 0 satellite program, according to a company statement.

The sensors use optical designs and algorithms to detect heat signatures from missile launches, including hypersonic weapon systems. The payloads are designed to provide enhanced sensitivity and tracking performance as part of a missile warning system.

The satellites, known as NGG, will provide continuous coverage over mid-latitudes to complement existing satellite constellations and new systems in Low Earth Orbit and Medium Earth Orbit. Lockheed Martin is building the satellites that will carry the Raytheon sensor payloads.

"Demand for resilient missile warning and tracking across all orbital regimes continues to accelerate," said Jeff McCall, vice president for Mission Solutions & Payloads at Raytheon.

Raytheon designed and built sensor payloads for two satellites total, with the first satellite completed and ready for initial launch capability. The company stated the sensors will address evolving space-based threats through improved tracking performance.

RTX reported 2025 sales of more than $88 billion and employs over 180,000 people globally. The company is headquartered in Arlington, Virginia.
