Weapons of Mass Destruction (WMD)


SSIXS

The Submarine Satellite Information Exchange Subsystem (SSIXS) is a DEC Ada program hosted by a MICROVAX III CPU. It is a UHF system that provides the submarine commander with the capability to exchange encrypted general-service and special-interest text message traffic between SSNs and SSBNs and the shore Broadcast Control Authorities (BCAs). Messages are transmitted from shore via satellite at scheduled intervals, called "group broadcasts." Between group broadcasts, submarines may transmit messages to the BCA or request messages held in queue, "query/response." These two modes of operation, group broadcast and query/response, permit the submarine commander to maintain either an active or passive posture.
