WASHINGTON — Northrop Grumman won a $45.5 million contract to launch a small weather satellite in 2025, the U.S. Space Force announced May 25.
The corporate’s Minotaur 4 rocket will launch a payload called Electro-Optical Infrared (EO/IR) Weather System (EWS) prototype that can reveal industrial weather imaging technologies for military use. The launch contract was a task order awarded by the U.S. Space Force’s Orbital Services Program-4.
OSP-4 is run by the Space Systems Command’s Small Launch and Targets Division at Kirtland Air Force Base, Albuquerque, Latest Mexico. It’s an indefinite delivery/indefinite quantity (IDIQ) contracting vehicle for the acquisition of launch services for payloads over 400 kilos.
The EWS weather satellite is a prototype made by General Atomics that can go to low Earth orbit for a three-year demonstration. The mission was designated USSF-261S-A.
“The EWS prototype will prove out latest EO/IR sensor technology to supply operational quality data to the DoD weather community and inform development of a less expensive and proliferated operational architecture,” the Space Systems Command said.
The Space Systems Command in January launched one other EWS prototype, a cubesat made by Orion Space Solutions. That one flew to orbit on the SpaceX Transporter-6 rideshare for a one-year demonstration.
Project seeks to fill demand for weather data
The EWS demonstrations are an effort to fill a Defense Department need for weather data because the military’s decades-old Defense Meteorological Satellite Program (DMSP) satellites are running out of fuel and projected to be out of service by 2026.
Congress for years has pressed DoD to seek out alternatives to DMSP and consider industrial options.
The U.S. military and allies depend on weather data from satellites to plan military operators corresponding to flight routes, combat search and rescue, maritime surface tracking efforts, enemy missile remark and intelligence collection.
