# Pentagon Cancels Missile-Warning Satellite Program After Northrop Grumman Delivers Sensor
Northrop Grumman delivered a sensor for the Space Force's Next Generation Overhead Persistent Infrared (Next Gen OPIR) program, but the Pentagon has terminated the entire effort. The contractor completed the payload for what would have been the program's first satellite, according to Space Force statements.
Next Gen OPIR aimed to replace aging Defense Support Program and Space-Based Infrared System satellites that detect missile launches. The program faced cost overruns and schedule delays spanning years. The Space Force will redirect efforts toward other infrared surveillance architectures instead.
Northrop Grumman built the sensor technology that would have provided enhanced missile-warning coverage from geostationary orbit. The cancellation marks a major setback for the contractor and represents a strategic pivot by the Pentagon's space branch.
The Space Force plans to pursue alternative approaches for maintaining overhead persistent infrared capability. No timeline for replacement programs has been announced. The decision reflects broader Pentagon concerns about ballooning space acquisition costs and the need for more adaptable surveillance systems.
Northrop Grumman's completed sensor component now faces an uncertain future, though the company may recoup development costs through existing contracts with the Defense Department.
