The Submarine Broadcast Support program was established to improve the reliability, efficiency and performance of the Extremely Low Frequency (ELF), Very Low Frequency (VLF), and Low
Frequency (LF) submarine broadcast systems. These transmission mediums (ELF/VLF/LF) comprise the primary line of Fleet Ballistic Missile Command, Control and Communications
(FBMC3). Two (2) ELF, four (4) VLF and five (5) LF shorebased transmitter sites are Emergency Action Message (EAM) relay points providing primary connectivity between Secretary of
Defense and SSBNs. Tasks are planned/ongoing to improve performance of ELF/VLF/LF broadcast capabilities consistent with changing operational requirements and upgrades to shore
infrastructure including integrating Internet Protocol (IP) capability in Broadcast Control Authorities (BCA). The Submarine LF/VLF VMEbus Receiver (SLVR) system replaces antiquated and
limited capability LF/VLF receivers on SSBNs (Ohio Class) and SSNs (Los Angeles/Seawolf/Virginia Class) submarines and at selected shore sites. It provides flexibility for technology
upgrades through the use of Pre-Planned Product Improvements (P3I). SLVR provides significant reductions in space and weight. The ELF Communications Ashore Robustness Program
(ECARP) will provide upgrades to existing ELF transmitter systems by replacing degraded, obsolete and high maintenance items that could preclude reliable operation well into the future.
JUSTIFICATION OF BUDGET YEAR REQUIREMENTS:
(1) Submarine Broadcast Upgrades: (W4008) Modernizes the Fixed Submarine Broadcast System (FSBS) by upgrading VLF/LF transmitters to maintain current fleet readiness. The
upgrades are necessary to replace obsolete or degraded equipment, which will have an adverse impact to the mission. VLF/LF transmission systems will incorporate new technologies based
on government and commercial best practices to make this medium of communication more efficient. Upgrades will also be accomplished to the broadcast generation subsystems at the
Broadcast Control Authorities (BCA) and Broadcast Keying Sites (BKS). The Clarinet Merlin Receivers will be replaced with a modern day equivalent as they have reached the end of service
life and their performance is threatened by obsolescence. The vacuum-tube AN/FRT-72 low frequency transmitters will be replaced with solid state equivalent to ensure reliable operation with
reduced life cycle cost. Composite bushings will replace the expensive and highly unique ceramic bushings used at the VLF/LF transmitter sites which are deteriorating and threaten the
availability of submarine broadcasts. The Submarine Operating Authority (SUBOPAUTH) provides consolidation and replication technologies used to unify and provide Continuity of Operations
(COOP) for the shore architecture of broadcast generation systems. The site upgrades will facilitate the commonality among the SUBOPAUTHs, reduce workload by automating processes,
drive to common operating procedures and augment the Submarine Community transition to IP based broadcasts. A new transmit terminal replaces legacy Integrated VERDIN Transmit
Terminal (IVTT) and KG-34 systems used for VLF/LF experiencing supportability and obsolesence issues. The addition of the new transmit terminal will provide logistical commonality with the
airborne counter part and flexible technology resulting in reduced total ownership costs. This technology is essential to the DoD Crypto Modernization Program, since it integrates a
replacement crypto device and allows removal of the aging KG-30 series crypto family.
(2) ECARP (Extremely Low Frequency (ELF) Communications Ashore Robustness Program): (W4013) Provides upgrades to existing ELF transmitter systems by replacing degraded,
obsolete and high maintenance items that could preclude reliable operation well into the future.
(3) NON-Fleet Modernization Program Equipment Installation and Fleet Modernization Program (FMP) Installation: (W4777) .
