Space Force Retires Its Last Defense Support Program Satellites
Original: Defense Support Program: Space Force Retires Its Last DSP Satellites
The US Space Force has retired the final satellites of the Defense Support Program, the Cold War-era infrared constellation that for decades provided early warning of ballistic missile launches. The aging spacecraft are being replaced by newer Space-Based Infrared System satellites, closing out a program that began in the early 1970s and marked a long-running chapter of American military space history.
Why now: The retirement of a historic military satellite program marks the end of an era and the completion of the transition to newer missile-warning systems.
