Travis Air Force Base's 60th Operations Support Squadron requires eight brand-name AN/PRC-163 Falcon IV handheld radios for secure military communications. This is a pre-solicitation notice, not a request for quotes or proposals, but the government intends to issue a firm-fixed-price RFQ with award anticipated on or about 28 Aug 2026. The acquisition is being conducted as a sole-source procurement with L3Harris Technologies Inc., as it is the only radio meeting the cryptographic and waveform requirements. Performance will occur at Travis Air Force Base, and only authorized suppliers may respond.
