Defense Satellite Communications System (DSCS III-03) was part of a US military satellite constellation placed in geosynchronous orbit to provide high-volume, secure voice and data communications. Phase II was a successor to the IDSCS (Initial Defense Satellite Communications System) program which began in 1966 with the launch of the first 8 satellites of this constellation. The DSCS III system was used for high priority communications such as the exchange of wartime information between defense officials and battlefield commanders. The military also used DSCS to transmit space operations and early warning data to various systems and users. Parola chiave :
