The Department of Defense, specifically the Air Force Nuclear Weapons Center (AFNWC), is hosting an Industry Day on January 14-15, 2026, to engage with industry partners regarding the modernization of Very Low Frequency (VLF) receiver capabilities across multiple DoD platforms. The event aims to provide detailed technical information and solicit feedback on requirements for designing, developing, testing, certifying, and producing a modern VLF receiver, which is critical for enhancing communication and operational effectiveness in defense systems. Attendance is encouraged for organizations with expertise in VLF technology, digital signal processing, and embedded systems, with all discussions classified at the Secret level; thus, participants must possess a valid Secret clearance. Interested attendees must pre-register by December 15, 2025, by contacting Matthew Daly at matthew.daly.6@us.af.mil, and are advised to submit Visitor Access Requests (VARs) in advance to ensure access to the classified sessions.
