Low frequency and very low frequency communication systems provide independent and survivable connectivity with our nuclear forces. The Fixed Submarine Broadcast System meets the minimum acceptable ballistic missile submarine connectivity requirements for day-to-day and crisis scenarios. FSBS must be modernized and sufficient sites maintained to assure we can communicate with forces when survivability and mission success require covertness. Currently, adequate funds are programed to modernize the FSBS. Planned modernization of the Fixed Submarine Broadcast System will allow a reduction in the number of ground stations required to support submarine communications.
