The Air Force Golden Horde Vanguard program successfully completed a second flight test of its collaborative weapon technologies using four Collaborative Small Diameter Bombs (CSDB). A CSDB is a Small Diameter Bomb modified with networked collaborative autonomy payloads. NCA technology gives weapons the ability to rapidly respond to changes in their battlespace without real-time human intervention, allowing them to effectively modify their actions to optimize mission success.

The CSDB technology team was led by the Air Force Research Laboratory and Scientific Applications & Research Associates as the prime contractor, which provided the home-on-GPS-jam seeker. Supporting contractors included L3Harris providing the Banshee 2 networked software defined radio; Georgia Tech Research Institute with the radio antenna, collaborative autonomy processor and algorithms; and The Boeing Company integrating the new technologies into its SDB-I weapons.

During the test, the CSDBs established communications with each other, identified a pop-up target, and followed the predetermined rules of engagement. They then proceeded to successfully evaluate and assign themselves to multiple targets, striking them in a time-synchronized manner. New program objectives demonstrated during this second CSDB flight test included four CSDB weapons in collaborative flight, adding to the two CSDBs used during first flight, and a synchronized time-on-target attack behavior. A third and final CSDB flight test is scheduled in the spring.

Software issues experienced during the first test were resolved during this second test, according to Steven Stockbridge, Golden Horde principal investigator. Subsequent to the first flight, the team resolved the weapon software issue, incorporated changes to further improve integrated system performance and verified the new software in hardware-in-the-loop simulations.

While initial program plans called for a Collaborative Miniature Air Launched Decoy flight demo and an integrated CSDB and CMALD flight demo, these plans have been cancelled. The Golden Horde program is now pivoting from inventory weapon demonstrations to developing and delivering a multi-tier digital weapon ecosystem: a live, virtual, constructive testing and demonstration capability known as the Colosseum. The Colosseum will be a fully integrated simulation environment with weapon digital twins, or a real-world weapon and a virtual clone, to more rapidly test, demonstrate, improve and transition collaborative autonomous networked technologies.
