Sicral-1 & Skynet 4F

SICRAL (Sistema Italiana de Communicazione Riservente Allarmi), the first national Italian system for satellite military telecommunications, has been developed by the SITAB consortium made up of Alenia Spazio, a Finmeccanica Company (70%), Fiat Avio (20%) and Telespazio (10%). The SICRAL 1 satellite can operate simultaneously on several frequency bands (SHF, EHF and UHF), a characteristic first in Europe, with the possibility to switch the bands onboard the satellite (first in the world). The UHF satellite repeater is Europe's most powerful and the only to operate inter-connected to the SHF/EHF band.

Skynet is a family of military communications satellites, now operated by Airbus Defence and Space on behalf of the UK Ministry of Defence, which provides strategic communication services to the three branches of the British Armed Forces and to NATO forces engaged in coalition tasks. The satellites were operated by Paradigm Secure Communications until October 2012 when the organisation was rebranded to Astrium Services.
