SICRAL 1B is a military communications satellite built by Thales Alenia Space for Italian Armed Forces. It is a dual-use spacecraft: Telespazio will use some of the satellite's transmission capacity and some will be used by the Italian defense ministry and NATO. The spacecraft is based on the Italsat 3000 bus and includes one EHF/Ka band, three UHF-band and five active SHF-band transponders. It is designed to be operable for 13 years.{{cite web |url=http://www.sea-launch.com/news_releases/2009/nr_090416.html |title=Sea Launch Counts Down to SICRAL 1B Launch |publisher=Sea Launch |url-status=dead |archiveurl=https://web.archive.org/web/20090419115317/http://www.sea-launch.com/news_releases/2009/nr_090416.html |archivedate=2009-04-19 }}
