USA-336, also known as SBIRS-GEO 6 (Space Based Infrared System - Geostationary 6), is a geostationary satellite operated by the United States Space Force (formerly operated by the United States Air Force). USA-336 forms part of the SBIRS High program. It is the last SBIRS Satellite to be launched and future mission will use new Next-Generation Overhead Persistent Infrared (NG-OPIR) Satellites.[1][4][5][6]
Overview
[edit]USA-336 is a three-axis stabilized satellite equipped with an Overhead Persistent Infrared (OPIR) scanner.[7] USA-336 uses its OPIR scanner and long-range surveillance to provide early warning for Ballistic Missile launches.[1][4] It will replace older Defense Support Program satellites.[7]
