Digital High Frequency (DHF) Payload Development & Integration

The contract seeks the design, development, and integration of a Digital High Frequency (DHF) payload to enhance secure and resilient nuclear command and control communications on the Sentinel intercontinental ballistic missile system. This payload must be engineered to operate reliably across all phases of a nuclear conflict—pre-nuclear, trans-nuclear, and post-nuclear environments—ensuring continuous communications integrity under extreme electromagnetic, thermal, and radiological conditions. The technology must meet stringent military specifications for survivability, anti-jamming capabilities, and cryptographic security to support strategic deterrence and national command authority functions. As a subcontract under the Department of Defense, this effort is managed by FA6800 Aficc 767 Esf and is tied to the Sentinel ICBM modernization program. The solicitation was posted on July 16, 2026, with a response deadline of August 3, 2026, and the place of performance is identified as Fort Johnson. The NAICS code 334511 indicates this work falls under the category of communication equipment manufacturing, underlining the technical precision and advanced engineering required. This subcontract underscores the urgency and sensitivity of maintaining uninterrupted nuclear command and control infrastructure amid evolving global threats.
