Defense Weather Satellite System

Overview
The Defense Weather Satellite System (DWSS) was a U.S. Department of Defense weather satellite system projected for launch in 2018. In January 2012, the U.S. Air Force cancelled the program.

DWSS was a follow-on for the Defense Meteorological Satellite Program (DMSP) mission. The DWSS, together with the still continuing Joint Polar Satellite System (JPSS) project, was to replace the National Polar-orbiting Operational Environmental Satellite System (NPOESS) project which itself was cancelled in January 2010.
