About this opportunity
The U.S. Navy, through the Naval Information Warfare Systems Command (NAVWAR), is seeking commercial solutions to replace four disparate tube-type VLF high-power transmission systems (HPTE) used by the shore-based Fixed Submarine Broadcast System (FSBS). This procurement falls under a Commercial Solutions Opening (CSO) announcement N0003925S0001 and is governed by title 10 U.S.C. 3458. The Navy requires high-reliability solutions that can support continuous 24/7 operations under all conditions, enable global coverage from existing FSBS transmission sites using current waveforms, and can be implemented with minimal site downtime. Interested vendors must submit Phase 1 Solution Briefs through the Procurement Integrated Enterprise Environment (PIEE) Solicitation module, with submissions limited to either five written pages using 12-point font or fifteen briefing slides. The submission deadline is October 21, 2025, and the government will not accept emailed submissions.
This opportunity does not utilize any set-aside designations and is open to all qualified vendors. The solicitation notice does not specify any incumbent contractors, potential award values, or budget ranges for this procurement. The requirement involves replacing four existing transmission systems, though specific quantities of replacement equipment are not detailed in the available information. The systems will continue to operate from existing FSBS transmission sites to maintain global coverage capabilities, suggesting that performance will occur at multiple shore-based locations where the current Fixed Submarine Broadcast System infrastructure is installed. The timeline for implementation emphasizes minimal site downtime during the transition from the current tube-type systems to the new solutions.
