GOES-18 (designated pre-launch as GOES-T) is the third of the "GOES-R Series", the current generation of weather satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The current and next satellites of the Series (GOES-16, GOES-17, GOES-18, and GOES-19) will extend the availability of the Geostationary Operational Environmental Satellite (GOES) satellite system until 2037. The satellite is built by Lockheed Martin in Littleton, Colorado. It is based on the A2100A satellite bus and will have an expected useful life of 15 years (10 operational after five years in orbit replacement).^[4]
