USA-336, also known as SBIRS-GEO 6 (Space Based Infrared System - Geostationary), 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.[1][4]

Overview

[edit]

USA-336 is a three-axis stabilized satellite equipped with an Overhead Persistent Infrared (OPIR) scanner.[5] 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.[5]
