ATLAS V TO LAUNCH SBIRS GEO Flight 5

• Rocket: Atlas V 421
• Mission: SBIRS GEO Flight 5
• Launch Date and Time: Mon., May 17, 2021 at 1:35 p.m. EDT (1735 UTC)
• Launch Location: Space Launch Complex-41, Cape Canaveral Space Force Station, Florida

Mission Information: A United Launch Alliance (ULA) Atlas V 421 rocket will launch the fifth Space Based Infrared System Geosynchronous Earth Orbit (SBIRS GEO Flight 5) missile detection and early warning satellite for the U.S. Space Force Space and Missile Systems Center. Liftoff will occur from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida.

Launch Notes:  This will be 144th mission for United Launch Alliance. It is the 87th Atlas V launch and the 8th in the 421 configuration. Atlas V successfully launched the first four SBIRS GEO satellites between 2011 and 2018.

Atlas V

ULA’s Atlas V rocket is a workhorse for the U.S. military, intelligence community and scientific researchers. Developed as a modular vehicle, each Atlas V is tailored to the needs of its passenger by adding as many as five side-mounted solid rocket boosters for increased lift performance and a variety of available payload fairings in various diameters and lengths to protect satellites during atmospheric ascent. The high-energy Centaur upper stage, which has been used to send spacecraft to every planet in our solar system, is incorporated into Atlas V to deliver the payloads to their intended destinations.

Space Launch Complex 41

Space Launch Complex 41, the East Coast home of the Atlas V rocket at Cape Canaveral Air Force Station in Florida, employs a “clean pad” concept of operations to ready launch vehicles and payloads for ascent into space. The rocket elements are assembled atop a Mobile Launch Platform inside the Vertical Integration Facility (VIF) located adjacent to the launch pad. The platform and fully stacked Atlas V then travels by rail approximately 1,800 feet northward from the VIF to the pad for the final countdown, fueling and liftoff. Complex 41 was constructed by the U.S. Air Force in the 1960s for the Titan rocket program. The site was rejuvenated in support of the Atlas V starting in the late 1990s.
