The Department of Defense, through the Naval Air Warfare Center Aircraft Division, is seeking to negotiate a sole source contract with Cornet Technology, Inc. for the procurement of Voice over Internet Protocol (VoIP) radio interface subsystems. These subsystems are critical for supporting communication upgrades for the Air Force Life Cycle Management Center and the Remote Radio Secure Voice System, as they are the only known solution that meets specific government requirements, including in-line external crypto support and compatibility with existing military radios. Interested parties should note that this is not a request for proposals, and responses must be submitted via email to Lauren Clemmens at lauren.a.clemmens.civ@us.navy.mil by the specified response date and time.
