SBIRS GEO Flight 4 Encapsulation

 

 

The U.S. Air Force’s Space Based Infrared System (SBIRS) Geosynchronous Earth Orbit (GEO) Flight-4 satellite, built by Lockheed Martin, completed encapsulation on January 9, 2018. SBIRS GEO Flight-4 will be the latest satellite to join the Air Force’s SBIRS constellation, which enhances our military's ability to detect missile launches, supports ballistic missile defense, expands technical intelligence gathering, and bolsters situational awareness on the battlefield. SBIRS GEO Flight-4 is expected to launch on January 18 aboard a United Launch Alliance Atlas V rocket.
