Editing NSA encryption systems (section)

=== Strategic forces ===

NSA has the responsibility to protect the command and control systems for nuclear forces. The [[KG-3]]X series is used in the US government's ''Minimum Essential Emergency Communications Network'' and the ''Fixed Submarine Broadcast System'' used for transmission of emergency action messages for nuclear and national command and control of US strategic forces. The Navy is replacing the [[KG-38]] used in [[nuclear submarine]]s with [[KOV-17]] circuit modules incorporated in new long-wave receivers, based on commercial [[VMEbus|VME]] packaging. In 2004, the US Air Force awarded contracts for the initial system development and demonstration (SDD) phase of a program to update these legacy generation systems used on aircraft.
