Raytheon, an RTX business, delivered its first sensor payload to prime contractor Lockheed Martin, keeping the U.S. Space Force Space Systems Command's first Next-Generation Overhead Persistent Infrared, or Next-Gen OPIR, Geosynchronous Earth Orbit (GEO) Block 0 missile warning satellite on track for a 2025 initial launch capability.

Designed to improve missile warning resilience and performance, two Next-Gen OPIR GEO satellites will eventually provide continuous coverage over mid-latitudes to the existing constellation. Raytheon is designing and building sensor payloads for both satellites.
Prior to delivery of the first payload, Raytheon completed a series of assessments including thermal vacuum testing. Thermal vacuum testing exposes the payload to a space-like environment and validates digital models to ensure the sensor meets design requirements. The second sensor payload is more than 60 percent completed and is scheduled to start thermal vacuum testing in early 2025.
