The AdvaNced airCraft Infrastructure-Less Launch And RecoverY (ANCILLARY) program aims to improve the capabilities of small vertical take-off and landing (VTOL) uncrewed aerial systems (UAS) by a factor of three compared to the current technology. The program focuses on developing new configurations, propulsion systems, and controls to increase payload weight and range/endurance, while also eliminating the need for extensive infrastructure typically required for UAS operations.
Steve Komadina, DARPA’s program manager for ANCILLARY, outlined the project’s objectives, which include enabling small UAS to operate from naval vessels without large mechanical launchers and landing/recovery equipment. This capability is intended to support operations in various environments, including ship decks and remote land locations, even under adverse weather conditions.
The program aims to allow a network of small UAS to be launched from ships, providing beyond-line-of-sight capabilities such as finding, fixing, tracking, and targeting (F2T2) surface vessels of interest. While the primary focus is on supporting Navy and Marine missions, other military branches, including the Army, Air Force, Special Operations Command, and Coast Guard, have shown interest in the potential applications of this technology for logistics, strike operations, and other special uses.
In Phase Ia, the ANCILLARY team explored conceptual designs from a diverse group of companies, which also included Leidos, AVX Aircraft, and Piasecki Aircraft. In Phase 1b of the ANCILLARY program, the six selected companies will continue with risk reduction, detailed analysis, and testing for an X-plane demonstrator over a ten-month period. This phase involves refining design processes and conducting component and configuration hover tests. At the end of this phase, teams will submit competitive proposals for Phase II, which will include detailed design, fabrication, and flight testing.
