In 2017, the United States Air Force requested US$1.4 billion in Fiscal Year 2018 for SBIRS, and funds for advance procurement of SBIRS 7 and 8. [22] While US$643 million in funding was provided for SBIRS in Fiscal Year 2019, funding for SBIRS 7 and 8 was eliminated in favor of a new program, Next-Gen OPIR (Next-Generation Overhead Persistent ...
USA-315, also known as SBIRS GEO-5, is a military satellite developed as a part of the Space-Based Infrared System. [ 2 ] [ 3 ] [ 1 ] The satellite aims to increase the capabilities of the United States Department of Defense in terms of missile defense and military intelligence.
Construction of the satellite was completed before it was required to launch, so the spacecraft was placed into storage. The U.S. Air Force later opted to launch Satellite Vehicle 4 (SV-4) first as SBIRS GEO-3, saving the cost of putting the newly-completed SV-4 into storage and additional testing that would be needed upon taking it back out.

SBIRS GEO-3 in orbit. SBIRS-GEO 3 was manufactured by Lockheed Martin Space and was built upon the A2100M, a militarized, radiation hardened satellite bus that provides power, attitude control, command and control, and a communications subsystem with five separate mission data downlinks to meet mission requirements, including system survivability and endurability requirements.
The SBIRS satellites are a replacement for the Defense Support Program early warning system. They are intended to detect ballistic missile launches, as well as various other events in the infrared spectrum, including nuclear explosions , aircraft flights, space object entries and reentries, wildfires and spacecraft launches .
