United Launch Alliance to launch the SBIRS-GEO 4 satellite.

United Launch Alliance is scheduled to launch the Space Based Infrared System Geosynchronous satellite or SBIRS-GEO 4 satellite from launch complex 41 at the Cape Canaveral Air Force Station in Florida. The launch, scheduled to take place on January 18, 2018, and will be ULA’s first launch from the Florida spaceport in the new year.

United Launch Alliance’s first launch of the year will be the NROL-47, launching from Vandenberg Air Force Base, California. NROL-47 is scheduled to take flight today, January 10, 2018, at 1:00 pm PST aboard a Delta IV Medium+ (5,2) rocket.

United Launch Alliance will launch the U.S. military’s fourth Space Based Infrared System Geosynchronous satellite, or SBIRS GEO 4, for missile early-warning detection. The rocket will fly in the 411 vehicle configuration with a four-meter fairing, one solid rocket booster, and a single-engine Centaur upper stage.

About the SBIRS-GEO 4 Payload

The Space Based Infrared System Geosynchronous satellite, or SBIRS-GEO 4, built by Lockheed Martin on the A2100 satellite bus is the fourth installment in the satellite constellation. The system enhances the U.S. Military’s ability to detect missiles, support ballistic missile defense, expand technical intelligence and bolster situational awareness on the battlefield. 

“SBIRS provides our military with timely, reliable and accurate missile warning and infrared surveillance information,” said Tom McCormick, vice president of Lockheed Martin’s Overhead Persistent Infrared systems mission area. “We look forward to adding GEO Flight 4’s capabilities to the first line of defense in our nation’s missile defense strategy.”

About the same time last year, United Launch Alliance launched the SBIRS-GEO 3 satellite for the USAF.
