The Navy is procuring a software‑defined radio (SDR) receiver for submarines and shore facilities, designated Low Band Universal Communications System (LBUCS) Receive (Rx) Version 2 (V2), capable of reliably receiving LF and VLF signals while a submarine is deep and moving fast and interoperable with an external End Cryptographic Unit (ECU). Offerors must submit a Phase 1 Solution Brief—either a written brief not to exceed five pages (12‑point font) or a slide brief not to exceed fifteen slides—via the PIEE Solicitation module as specified in the posting. The notice requires vendors to select a single solution brief; there is no menu of multiple topics to choose from. Submissions must be made through PIEE (email not accepted) and contractors will need the appropriate clearance to receive the government‑furnished ECU for development and testing.
