The Department of Defense, specifically the Navy, is seeking proposals for the development of a Small Type-1 Encryption device for Aircraft, Littoral, and Terrestrial Higher-than-Secret (STEALTH) applications. The objective is to create very small modular NSA Type-1 High Assurance Internet Protocol Encryptor (HAIPE) modules that support advanced encryption features, including multi-frequency and carrier-hopping capabilities, while ensuring easy removal and integration into various tactical systems. This initiative is critical for enhancing secure communications across military platforms, allowing for the handling of classified information in a compact and efficient manner. The solicitation is currently in the pre-release phase, with an open date set for January 8, 2025, and a close date of February 5, 2025.
