Watchdog expects delays to Space Force’s next missile warning satellites | Defense News

According to a recent Government Accountability Office report, the U.S. Space Force’s next generation missile warning constellation’s launch will likely be delayed beyond the original anticipated launch of 2025. The Next Generation Overhead Persistent Infrared constellation (OPIR) is being developed to eventually replace the Department of Defense’s main missile warning satellite program. The Next Gen OPIR will use a combination of infrared sensors in geostationary and elliptical orbits to detect missile launches from anywhere on Earth. The planned expenditure by Space Force on this program is $14.4b through 2025
