Two candidate payloads for the U.S. Space Force\u2019s Next Generation Overhead Persistent Infrared satellites have passed their preliminary design review, with critical design review expected in fall 2021.<\/p>\n\n\n\n

Next Gen OPIR is to replace the Space-Based Infrared System, a constellation of satellites hosting infrared sensors used to detect and track ballistic missile threats. The Space Force says the new system will be more survivable than its predecessor.<\/p>\n\n\n\n

The Space and Missile Systems Center plans to place five satellites in the initial constellation: three geosynchronous, or NGG, satellites built by Lockheed Martin; and two polar satellites being built by Northrop Grumman<\/a>. The two infrared payloads that passed preliminary design review are for the first two NGG satellites.<\/p>\n\n\n\t
