Raytheon Delivers 2nd Missile-Warning Sensor to USSF

April 28, 2026

Raytheon, an RTX (NYSE: RTX) business, has delivered its second sensor to Lockheed Martin for the U.S. Space Force's Next-Generation Overhead Persistent Infrared (Next-Gen OPIR) Geosynchronous Earth Orbit (GEO) Block 0 satellite program. The satellites, commonly referred to as NGG, will provide enhanced missile warning and tracking to address evolving space-based threats.

Raytheon's sensor payloads use advanced optical designs and algorithms to detect the heat signatures of missile launches, including hypersonic weapon systems and other advanced threats. The sensors deliver improved sensitivity and tracking performance as part of an advanced missile warning architecture. 

"Demand for resilient missile warning and tracking across all orbital regimes continues to accelerate," said Jeff McCall, vice president for Mission Solutions & Payloads for Raytheon. "Programs like NGG demonstrate how high-altitude, long-duration observation sensing unlocks new mission coverage in key areas."

The NGG satellites built by Lockheed Martin will provide continuous coverage over mid-latitudes, complementing the current satellite constellation and new entrants in Low Earth Orbit and Medium Earth Orbit.

Raytheon designed and built the sensor payloads for two satellites, with the first satellite complete and ready to support initial launch capability.
